Impact of dental visiting patterns on oral health: A systematic review of longitudinal studies

AIM

To systematically review longitudinal studies investigating the impact of dental visiting patterns on oral health across the life course.

METHODS

Five databases (MEDLINE, Embase, Scopus, Web of Science, CINAHL) were searched up to March 2023. Results were screened based on eligibility criteria in a two-stage process: title and abstract, and full-text review. A backward search of reference lists and a forward search of citations of the included papers was also conducted. The quality of the included papers was assessed using the Newcastle-Ottawa Scale. Key study information was extracted and a narrative synthesis of the findings was performed.

RESULTS

Eleven papers from five longitudinal studies in five countries (Australia, Brazil, China, New Zealand, Sweden) met the inclusion criteria. Studies of moderate to high quality consistently reported that regular dental attendance was associated with having less dental caries experience, fewer missing teeth and better oral health-related quality of life. Inconsistent findings were observed for decayed teeth, and no association was found for periodontal condition.

CONCLUSIONS

This review highlights an association between regular dental visiting pattern and improved oral health, notably less dental caries experience and better oral health-related quality of life. Dental attendance emerges as an important predictor of oral health across the life course, underscoring the importance of routine dental care.

How to have healthy conversations: Contemporary Evidence and Behaviour Change Tools in support of Delivering Better (Oral) Health

The aim of this paper is to provide dental professionals with insight into how the science of behaviour change can be used to support patients to change their oral health behaviours. The paper describes how the fourth version of Delivering Better Oral Health (DBOHv4) published in November 2021, brings together the theory plus key principles and practical tools in Chapter 3 "Behaviour change", to help front-line clinicians achieve the best effect. DBOH is freely available to all online at gov.uk and is a key resource for dental teams for the prevention of oral diseases.

Telehealth technologies in care homes: a gap for dentistry?

BACKGROUND

Telehealth technologies are playing an increasing role in healthcare. This study aimed to review the literature relating to the use of telehealth technologies in care homes with a focus on teledentistry.

METHODS

Khangura et al.'s (Evidence summaries: the evolution of a rapid review approach. Syst Rev 2012;1:10) rapid review method included an electronic database search on Embase, PubMed, Web of Science and OpenGrey. Out of 1525 papers, 1108 titles and abstracts were screened, and 75 full texts assessed for eligibility. Risk of bias was assessed using the Mixed Methods Assessment Tool 2018.

RESULTS

Forty-seven papers (40 studies) from 10 countries, published 1997-2021, were included in the review, four studies related to teledentistry. Whilst some preferred in-person consultations, perceived benefits by stakeholders included reduced hospitalization rates (n = 14), cost-savings (n = 8) and high diagnostic accuracy (n = 7). Studies investigating teledentistry using intra-oral cameras reported that teleconsultations were feasible with potentially high diagnostic accuracy (n = 2), cost-savings (n = 1) and patient acceptability (n = 1).

CONCLUSION

There is limited published research on teledentistry, but wider telehealth research is applicable to teledentistry, with findings suggesting that telehealth technologies play a role in care homes consultations that are acceptable, cost-saving and with potential diagnostic accuracy. Further research is needed on the mode, utility and acceptability of teledentistry in care homes.

Learning in conversation-A feasibility pilot study involving dental students and older people

INTRODUCTION

Older people represent a growing proportion of the population in most high-income countries. The impact of oral diseases on health and well-being is far-reaching, and future graduates should be able to meet their needs in this phase of life. This research tested the feasibility of involving dental students in direct community engagement to explore older peoples' oral health concerns and information needs.

MATERIALS AND METHODS

Seventeen older people were recruited locally to attend workshops with eight dental students in a health and well-being centre. First, older people selected oral health-related topics important to them, raising relevant questions and concerns. Students provided evidence-informed feedback on these selected topics at a subsequent workshop. Participants (students and older people) reflected on their involvement (via questionnaires, discussions and personal reflections). Qualitative data were analysed using thematic analysis. The structure, process and outcome of the study were explored.

RESULTS

Structure: Both students and older people were willing to participate in workshops. Workshops in the community facilitated active engagement between both groups without the constraints of clinics.

PROCESS

Students considered pre-workshop preparations adequate but raised issues about their ability to manage 'strong characters' within discussion groups.

OUTCOME

Older people welcomed the initiative. Important topics raised by them were addressed by students giving them advice on maintaining their oral health. Students reported an improved understanding of how older people can be supported and expected a significant impact on future practice.

CONCLUSION

Student involvement in direct community engagement was welcomed by all, demonstrating the feasibility and positive impact of the design whilst highlighting issues of importance for older people's oral health.

Caries clusters at lesion-severity thresholds: A Sierra Leone case study

OBJECTIVES

Despite being almost entirely preventable, globally, dental caries is extremely prevalent. Moreover, dental caries will continue to present an even larger challenge for lower income countries, particularly those in the African context, as they transition to a more Western diet. Hence, epidemiological data providing insight into disease patterns and trends is critical to inform public health action. The purpose of this study was to examine dental caries clusters by caries detection threshold among 15-year-old adolescents in Sierra Leone, using data from the latest national survey, and to explore associated sociodemographic factors.

METHODS

This paper presents a secondary analysis of oral health data on 490 15-year-olds from the Sierra Leone national oral health survey of schoolchildren. Hierarchical cluster analysis of dental caries experience was conducted across all surfaces at four decay detection thresholds using the International Caries Detection and Assessment System (ICDAS) (clinical: ICDAS 2-6, cavitated: ICDAS 3-6, obvious: ICDAS 4-6 and extensive obvious: ICDAS 5-6 decay) across the four regions of Sierra Leone. Ordered logistic regression was used to estimate the association of sociodemographic factors with generated clusters relating to clinical and obvious decay experience. These are of both clinical and epidemiological relevance.

RESULTS

A 3-cluster decay pattern representing a 'low' to 'high' decay experience distribution was observed under each decay detection threshold across surfaces. For clinical decay (including visual enamel caries), 28.8% had low, 55.1% medium and 15.9% high caries status. In the adjusted model, the only significant risk factor across obvious and clinical decay thresholds was region, with adolescents outside the Western region more likely to experience decay.

CONCLUSION

This study suggests that adolescents in Sierra Leone fall into three distinct caries clusters: low, medium to high decay experience distribution, regardless of decay threshold. It reinforces the importance of recognizing dental caries detection thresholds and the use of contemporary epidemiological methodology. This suggests that adolescents outside the Western region are likely to have higher caries experience. The data also provides insight to the nature of adolescents in each cluster and should help to inform policy and planning of the integration of oral health into primary care and school systems.

Reconciling duty: a theory and typology of professionalism

BACKGROUND

Professionalism is expected of health professionals and advocated by professional regulators in the United Kingdom (UK). Concepts of professionalism have evolved in sociological discourse and its meaning for dentistry is unclear. It is, none-the-less, considered a core domain of dental education and professional practice by the United Kingdom regulator, the General Dental Council. This paper reports the sense-making process, or social process, of professionalism in practice within England.

AIM

To explore the research question 'What does dental professionalism mean in practice?

METHODS

Taking a constructivist grounded theory approach, involving purposive and theoretical sampling, 24 dental professionals were recruited to participate in this qualitative study. In-depth, semi-structured interviews were conducted by one interviewer (AT). Interviews were recorded, transcribed verbatim, and analysed leading to the development of a theory grounded in the data.

RESULTS

A focus on the social-professional constructs used by participants to make sense of their experiences, resulted in a grounded theory where Reconciling Duty emerged as the core category. This represents a process of meeting professional duties to different parties that are often mutually exclusive. It is comprised of three supporting categories: Applying order to the system, where individuals attempt to identify what constitutes professional attitudes and behaviours, Rationalising what is fair, where individuals make judgements on how the conflict between duties should be resolved, and finally Responding to the System, where individuals attempt to actualise these desired resolutions in the context of the complex social system in which they practice. Three dentist archetypes (typologies) emerged, which involved a personal (Type 1), patient (Type 2), or a societal (Type 3) compromise.

CONCLUSION

Professionalism can be conceptualised as process of reconciling multiple, competing, legitimate duties to different parties, in seeking a fair solution. Once this has been identified, individuals need to work within the complex system of dentistry to make their identified outcome a reality. The findings suggest that using the theory of Reconciling Duty helps us to engage with the meaning that the participants drew from the term 'professionalism', and anchors it in the lived, everyday professional experiences and challenges faced. A novel typology is proposed, commensurate with calls for a systems approach to the topic.

Modelling a Consultant Workforce for the United Kingdom: needs-based planning for Dental Public Health

OBJECTIVE

To develop a needs-based workforce planning model to explore specialist workforce capacity and capability for the effective, efficient, and safe provision of services in the United Kingdom (UK); and test the model using Dental Public Health (DPH).

BASIC RESEARCH DESIGN

Data from a national workforce survey, national audit, and specialty workshops in 2020 and 2021 set the parameters for a safe effective DPH workforce. A working group drawing on external expertise, developed a conceptual workforce model which informed the mathematical modelling, taking a Markovian approach. The latter enabled the consideration of possible scenarios relating to workforce development. It involved exploration of capacity within each career stage in DPH across a time horizon of 15 years. Workforce capacity requirements were calculated, informed by past principles.

RESULTS

Currently an estimated 100 whole time equivalent (WTE) specialists are required to provide a realistic basic capacity nationally for DPH across the UK given the range of organisations, population growth, complexity and diversity of specialty roles. In February 2022 the specialty had 53.55 WTE academic/service consultants, thus a significant gap. The modelling evidence suggests a reduction in DPH specialist capacity towards a steady state in line with the current rate of training, recruitment and retention. The scenario involving increasing training numbers and drawing on other sources of public health trained dentists whilst retaining expertise within DPH has the potential to build workforce capacity.

CONCLUSIONS

Current capacity is below basic requirements and approaching 'steady state'. Retention and innovative capacity building are required to secure and safeguard the provision of specialist DPH services to meet the needs of the UK health and care systems.

Journey towards a dental career: the career decision-making journey and perceived obstacles to studying dentistry identified by London's secondary school pupils and teachers

Objective To explore the career decision-making journey towards dentistry and identify possible challenges and supports in this process as perceived by academically able, science-minded, London school pupils and their careers teachers.Methods A mixed-methods study was conducted using a purposive sample of London schools. Focus groups (n = 13) with 91 pupils aged 14-18 years and a survey of career teachers (n = 12) were conducted at a range of school-types. A topic guide, informed by the literature and previous research, guided discussions. Ethical approval was obtained from King's College London Research Ethics Committee (BDM/10/11-17 and 14/15-40). School, teacher, parental and pupil written informed consent were obtained. Data were transcribed and analysed thematically using framework methodology.Results Four distinct phases of the career decision-making journey were identified: 1) initiation of aspiration, with wider influences promoting medicine as a primary aspirational career option; 2) exposure to dentistry as a career, leading to recognition of dentistry as an alternative; 3) exploration of the career; and 4) the application process. Dentistry received little early consideration in this process. Greater representation of dental professionals within the school, access to work experience, and support in the student application process were identified as possible supports.Conclusions The findings suggest a four-phase journey towards a dental career, which may be enhanced by engagement of dental professionals at each stage. This may be particularly helpful in widening participation from under-represented groups.

Oral Health and Community Nursing: a Practical Guide to the Delivering Better Oral Health Toolkit for Adults

Despite being largely preventable, oral diseases are the major contributor to chronic conditions nationally and globally. If left untreated, oral diseases have many harmful effects throughout life on our patients including pain and infection, and can lead to difficulties with eating, sleeping, socialising and wellbeing. Oral health inequalities exist across our population, and particularly affect vulnerable, disadvantaged and socially excluded groups in society. Oral health is a key indicator for overall health, and is inextricably interlinked with general health. Hence, existing health messages that community nursing teams provide contribute towards oral health. Community nurses are in an established position to provide and reinforce positive oral health messages to their patients, as well as signpost to available dental services. This paper aims to support community nurses with a practical resource for key evidence-based oral health preventative advice, and input into how their patients can access dental care.

Methodology and outcome of trials involving older adults in UK care homes: A rapid review

BACKGROUND

The United Kingdom (UK) has a well-developed health and social care system, and strong research governance. However, there is limited evidence to guide best research practice among vulnerable older people in care homes and there is no consensus on clinical trial methodology that is deliverable in this setting.

OBJECTIVES

To review the literature on trials conducted among older adults residing in care homes within the UK and collate evidence on their methodological characteristics and outcomes.

METHODS

A systematic rapid review methodology was employed. MEDLINE, EMBASE and CENTRAL were searched in two incremental stages: stage 1 searched for oral health-related trials conducted within the UK care homes up to July 2021, whereas stage 2 sought for general health-related trials in the same setting from 2011 to 2021. The quality of included studies was assessed using Cochrane's RoB 2 and ROBINS-I tools. Findings were summarised descriptively.

RESULTS

Five oral health and 33 general health-related trials involving care home residents were included for analysis. The most common trial design was parallel group with two arms (n = 25) involving individual randomisation (n = 21). Consent was mainly obtained from residents and/or their proxies (n = 24), followed by residents only (n = 13) and care homes only (n = 1). Based on available data, the number needed to screen to recruit one participant ranged from 2 to 40 (median: 3; Q1-Q3: 2-9). Attrition rates ranged from 0% to 73% (median: 21%; Q1-Q3: 13%-32%) for follow-up periods between 1 and 52 weeks. The studies were of mixed methodological quality.

CONCLUSION

This rapid review outlines the methodological characteristics and outcomes of trials conducted among older adults in UK care homes. The findings of this review provide valuable information to assist in navigating and designing future research in this complex setting.

Oral Health Workforce in Africa: A Scarce Resource

The World Health Organization (WHO) African Region (AFR) has 47 countries. The aim of this research was to review the oral health workforce (OHWF) comprising dentists, dental assistants and therapists, and dental prosthetic technicians in the AFR. OHWF data from a survey of all 47 member states were triangulated with the National Health Workforce Accounts and population data. Descriptive analysis of workforce trends and densities per 10,000 population from 2000 to 2019 was performed, and perceived workforce challenges/possible solutions were suggested. Linear regression modelling used the Human Development Index (HDI), years of schooling, dental schools, and levels of urbanization as predictors of dentist density. Despite a growth of 63.6% since 2010, the current workforce density of dentists (per 10,000 population) in the AFR remains very low at 0.44, with marked intra-regional inequity (Seychelles, 4.297; South Sudan 0.003). The stock of dentists just exceeds that of dental assistants/therapists (1:0.91). Workforce density of dentists and the OHWF overall was strongly associated with the HDI and mean years of schooling. The dominant perceived challenge was identified as 'mal-distribution of the workforce (urban/rural)' and 'oral health' being 'considered low priority'. Action to 'strengthen oral health policy' and provide 'incentives to work in underserved areas' were considered important solutions in the region. Whilst utilising workforce skill mix contributes to overall capacity, there is a stark deficit of human resources for oral health in the AFR. There is an urgent need to strengthen policy, health, and education systems to expand the OHWF using innovative workforce models to meet the needs of this region and achieve Universal Health Coverage (UHC).

Unmet need in Sierra Leone: a national oral health survey of schoolchildren

OBJECTIVE

Sierra Leone (SL), in West Africa, with a population of over 7.5 million people has suffered the effects of a civil war previously, and more recently Ebola & Covid-19. Dental care is very limited, mostly in the capital Freetown and the private sector. No dental education is available in the country. The objective of this research was to investigate the oral health needs of schoolchildren at key ages, to inform future action.

MATERIALS AND METHODS

This first national oral health survey of schoolchildren at 6-, 12- and 15-years was conducted in urban and rural settings across all four regions using a multi-stage cluster sampling in line with the WHO guidelines, adapted according to contemporary survey methods to include 'International Caries Detection and Assessment System (ICDAS)'. Whilst parents were invited to complete a questionnaire for 6-year-old children, 12- and 15-year-olds self-completed a questionnaire. Data were weighted according to age and regional population and analysed using STATA v.15 and SPSS v.22.

RESULTS

A total of 1174 children participated across 22 schools from all four regions. Dental caries was prevalent (over 80% of all age-groups having clinical decay; ICDAS score ≥ 2) and largely untreated. No children had fillings and only 4% had missing teeth. Amongst 6, 12 and 15-year-olds, average decay levels at ICDAS > 3 threshold was 3.47 (primary teeth), 2.94 and 4.30 respectively. Almost, 10% (n = 119) of all children reported experiencing pain in their teeth with 7% (n = 86) children having PUFA lesions present. At least one in five children required one or more dental extractions. 'Age' was a significant predictor of dental caries experience and the odds of having dental caries experience was higher in rural areas at D_3-6MFT (p < 0.05).

CONCLUSION

The findings demonstrate a vast unmet oral health need in the children of SL. Using ICDAS as an epidemiological tool in a low-income country provides valuable insight to the pattern of oral disease to inform health service planning. Urgent action is required to address this silent epidemic.

Health and Wellbeing of Clinical Dental Care Professionals: A Systematic Review

BACKGROUND

There has been much research relating to stressors in the dental environment and concerns over dentists' health and wellbeing. The determinants of dentists' health and wellbeing within the UK include macro-factors, such as healthcare systems and regulation; meso-factors, such as job specification and workplace characteristics; and micro-factors, such as personal aspects, professional career level, and personal and professional relationships. Given the challenges in dentistry, research is needed to investigate the key determinants relating to the health and wellbeing of clinical dental care professionals (DCPs) nationally.

AIM

To review the literature on the key determinants of health and wellbeing among dental hygienists, dental therapists, clinical dental technicians, and orthodontic therapists in the UK.

MATERIALS AND METHODS

A systematic review of the literature was conducted across seven databases. The records were screened by title, abstract and full text based on the study inclusion criteria. Extraction of data and a qualitative synthesis of the included studies was performed. A mixed methods appraisal tool was used to quality assess for risk of bias.

RESULTS

Twelve studies were included in this review, eleven of which were medium to high quality (5*, 4*) and one low quality (2*). Ten studies focused on dental therapists, and/or hygienists, with only one each on orthodontic therapists and clinical dental technicians. Job satisfaction and professional careers were the primary factors explored in the included studies and clearly identified as determinants of health and wellbeing. However, there was evidence of these being associated and linked with a range of determinants at macro-, meso-, and micro-levels, with a general lack of evidence on the overall health and wellbeing.

CONCLUSION

There is currently very limited evidence on the key determinants of health and wellbeing of clinical DCPs within the UK, but the available evidence maps to the same domains as dentists. Further well conducted research examining the overall health and wellbeing is required, with consideration of the full matrix of possible factors.

Accreditation and professional integration experiences of internationally qualified dentists working in the United Kingdom

INTRODUCTION

Regulatory processes for Oral health care professionals are considered essential for patient safety and to ensure health workforce quality. The global variation in their registration and regulation is under-reported in the literature. Regulatory systems could become a barrier to their national and international movement, leading to loss of skilled human resources. The General Dental Council is the regulatory authority in the UK, one of the nine regulators of health care overseen by the Professional Standards Authority.

AIM

The aim of this paper is to present the professional integration experiences of internationally qualified dentists (IQDs) working in the UK, against the background of regulation and accreditation nationally.

METHODS

Registration data were obtained from the General Dental Council to inform the sampling and recruitment of research participants. Semi-structured interviews of 38 internationally qualified dentists working in the United Kingdom were conducted between August 2014 and October 2017. The topic guide which explored professional integration experiences of the dentists was informed by the literature, with new themes added inductively. A phenomenological approach involving an epistemological stance of interpretivism, was used with framework analysis to detect themes.

RESULTS

Internationally qualified dentist's professional integration was influenced by factors that could be broadly classified as structural (source country training; registration and employment; variation in practising dentistry) and relational (experiences of discrimination; value of networks and support; and personal attributes). The routes to register for work as a dentist were perceived to favour UK dental graduates and those qualifying from the European Economic Area. Dentists from the rest of the world reported experiencing major hurdles including succeeding in the licensing examinations, English tests, proving immigration status and succeeding in obtaining a National Health Service performer number, all prior to being able to practice within state funded dental care.

CONCLUSION

The pathways for dentists to register and work in state funded dental care in UK differ by geographic type of registrant, creating significant inconsistencies in their professional integration. Professional integration is perceived by an individual IQD as a continuum dictated by host countries health care systems, workforce recruitment policies, access to training, together with their professional and personal skills. The reliance of the UK on internationally qualified dentists has increased in the past two decades, however, it is not known how these trends will be affected by UK's exit from the European Union and the COVID-19 pandemic.

Editorial - Delivering Better Oral Health 2021 - What's new and where next?

Delivering Better Oral Health (DBOH) was fi rst published in 2007 (Department of Health et al., 2007) at the request of the Department of Health to the British Association of Community Dentistry (BASCD). It was led by Dr Sue Gregory, who was at that time President of BASCD; and, thereafter, appointed Deputy Chief Dental Officer for England. The purpose of the document was to support dental teams in a more preventive approach to dental care based on the best available evidence. Practitioners have access to an enormous amount of information, and it was intended that DBOH would provide a simple guide to the evidence, explaining what the research meant in practical terms for the preventive advice and treatment of their patients. The approach promoted preventive care for all patients and additional support for those most at risk of poor oral health. DBOH was to be a living document, regularly updated. It was revised in 2009 and 2014, when after the Health and Social Care Act (2012), Public Health England took on the leadership of its development. In 2017 revisions responsed to changes in guidance; the publication by the Scientific Advisory Committee on Nutrition of the Carbohydrates and Health Report (SACN, 2015) which led to a revised healthier eating section and the Chief Medical Officers' (2016) new guidelines on alcohol were also incorporated.

Perspectives of community-dwelling older adults with dementia and their carers regarding their oral health practices and care: rapid review

AIM

To review evidence on oral health practices, beliefs/views and experiences of community-dwelling older adults living with dementia, including their carers.

MATERIALS AND METHODS

A search of key terms across six databases including Pubmed, Web of Science and OVID (Embase, MEDLINE [R] and PsycINFO) and Google Scholar was conducted, supplemented by reference screening. The Mixed Methods Appraisal Tool (MMAT) 2018 was used to assess the methodological quality.

RESULTS

Eighteen studies reported across 19 papers were included in the review. Papers largely focused on normative needs (n = 13), whilst also reporting oral health-related experiences (n = 2), practices (n = 7), and beliefs/views (n = 9), of community dwellers with dementia. Generally, people living with dementia presented with poor oral and dental health, the exception being one study where dental care was integrated with memory clinic services. Maintenance of oral health focused only on toothbrushing. Overall, people living with dementia have reduced capacity for self-performed oral hygiene and high reliance on caregivers. There was a paucity of evidence on their perceptions of oral health and quality of life, the findings of which were equivocal, with weak evidence suggesting possible difficulty in identifying and communicating their needs. Experiences of accessing dental care, when explored, appear to be system dependent.

CONCLUSION

There was limited research evidence on oral health-related practices, beliefs/views and experiences of people with dementia. Recommendations for future research are presented.

The mouth and oral health in the field of dementia

An ageing population, an estimated 47 million people currently living with dementia, and predictions of a threefold increase in people living with a diagnosis by 2050 have led the WHO to declare dementia a public health priority. Emerging research also suggests that dementia is linked to poor oral health and that oral health declines alongside cognitive decline. Drawing on Bourdieu's concepts of field and capital, this paper presents an analysis of interview data from participants with dementia, carers and carer/diagnosed dyads participating in a qualitative study of the mouth and oral health. We argue that Bourdieu's conceptual toolkit provides a way of contextualising experiences of oral health within dementia and un-picking the multi-layered impact of structure, institutions, biology, resource mobilisation and self in the context of a progressive disease which ultimately challenges knowledge of the self and the ability to interact with the world around us.

Formulation and fluoride content of dentifrices: a review of current patterns

Introduction Consumer oral hygiene products play a key role in improving and maintaining population oral health. The oral personal care market is rapidly diversifying; a growing number of dentifrices marketed a 'natural' and fluoride-free are entering mainstream retailers, which may have implications for the oral health of the population 'with regards to caries risk.Aims To investigate the range of fluoride concentrations, flavour formulations and delivery mechanisms of dentifrices available on the UK market.Methods A cross-sectional survey was used to catalogue dentifrices sold in a range of supermarkets, high-street pharmacy and health chains, and specialist online retailers. In addition, a standard search engine was used to examine dentifrice brands being sold in the UK. The fluoride content was recorded as parts per million (ppm) and the product name data were analysed for key terms using Microsoft Excel. Excluded from the survey were mouthwashes, rinses and non-dentifrice whitening products.Results Five hundred different toothpaste, tooth powder and tablet products from 95 different brands were recorded. Sixty percent of these contained a fluoride concentration of 1,000 ppm or above. Forty-five percent of all products had the recommended adult concentration of at least 1,350 ppm. Almost one-third (31%) contained no fluoride and 4% of products did not specify the absence, presence or concentration of fluoride.Conclusions This study has quantified and confirmed the increasingly diverse range of dentifrices for sale in the UK. A large number of fluoride-free products exist within a growing 'natural' and 'organic market'. The study also gives oral health professionals an insight into the diverse types of products available to consumers in order to appropriately advise patients on caries prevention.

Needs-led human resource planning for Sierra Leone in support of oral health

BACKGROUND

In Sierra Leone (SL), a low-income country in West Africa, dental care is very limited, largely private, and with services focused in the capital Freetown. There is no formal dental education. Ten dentists supported by a similar number of dental care professionals (DCPs) serve a population of over 7.5 million people. The objective of this research was to estimate needs-led requirements for dental care and human resources for oral health to inform capacity building, based on a national survey of oral health in SL.

METHODS

A dedicated operational research (OR) decision tool was constructed in Microsoft Excel to support this project. First, total treatment needs were estimated from our national epidemiological survey data for three key ages (6, 12 and 15 years), collected using the 'International Caries Classification and Management System (ICCMS)' tool. Second, oral health needs were extrapolated to whole population levels for each year-group, based on census demographic data. Third, full time equivalent (FTE) workforce capacity needs were estimated for mid-level providers in the form of Dental Therapists (DTs) and non-dental personnel based on current oral disease management approaches and clinical timings for treatment procedures. Fourth, informed by an expert panel, three oral disease management scenarios were explored for the national population: (1) Conventional care (CC): comprising oral health promotion (including prevention), restorations and tooth extraction; (2) Surgical and Preventive care (S5&6P and S6P): comprising oral health promotion (inc. prevention) and tooth extraction (D5 and D6 together, & at D6 level only); and (3) Prevention only (P): consisting of oral health promotion (inc. prevention). Fifth, the findings were extrapolated to the whole population based on demography, assuming similar levels of treatment need.

RESULTS

To meet the needs of a single year-group of childrens' needs, an average of 163 DTs (range: 133-188) would be required to deliver Conventional care (CC); 39 DTs (range: 30-45) to deliver basic Surgical and Preventive care (S6P); 54 DTs for more extended Surgical and Preventive care (S5&6P) (range 38-68); and 27 DTs (range: 25-32) to deliver Prevention only (P). When scaled up to the total population, an estimated 6,147 DTs (range: 5,565-6,870) would be required to deliver Conventional care (CC); 1,413 DTs (range: 1255-1438 DTs) to deliver basic Surgical and Preventive care (S6P); 2,000 DTs (range 1590-2236) for more extended Surgical and Preventive care (S5&6P) (range 1590-2236); and 1,028 DTs to deliver Prevention only (P) (range: 1016-1046). Furthermore, if oral health promotion activities, including individualised prevention, could be delivered by non-dental personnel, then the remaining surgical care could be delivered by 385 DTs (range: 251-488) for the S6P scenario which was deemed as the minimum basic baseline service involving extracting all teeth with extensive caries into dentine. More realistically, 972 DTs (range: 586-1179) would be needed for the S5&6P scenario in which all teeth with distinctive and extensive caries into dentine are extracted.

CONCLUSION

The study demonstrates the huge dental workforce needs required to deliver even minimal oral health care to the Sierra Leone population. The gap between the current workforce and the oral health needs of the population is stark and requires urgent action. The study also demonstrates the potential for contemporary epidemiological tools to predict dental treatment needs and inform workforce capacity building in a low-income country, exploring a range of solutions involving mid-level providers and non-dental personnel.

Supporting dentists' health and wellbeing - a qualitative study of coping strategies in 'normal times'

Background Research has highlighted multiple determinants of dentists' health and wellbeing, and has raised concerns over workforce morale and retention. Limited research has been undertaken on possible solutions. Thus, the aim was to explore the coping strategies used or advocated by dentists to protect and support their health and wellbeing.Methods This qualitative study involved a purposive sample of dentists working in England taking account of age, gender, career stage, work sector, geographical area, position and route of entry to registration. Dentists were approached via gatekeepers across England to participate in semi-structured interviews. A topic guide, informed by past research, was used to guide the discourse. Informants' views were audio-recorded and field notes were made. Data were transcribed and analysed using an interpretative phenomenological approach to generate theory with the support of the framework methodology.Results Twenty dentists were interviewed from a range of backgrounds. Self-reported coping strategies included a range of strategies for 'taking control', including 'embracing self-care' and 'seeking professional support', while drawing on 'supportive personal and social networks'. Managing professional careers included diversifying through greater 'mixing' of NHS with private work, privatising, specialising, or combining dentistry with another role. Strengthening job security and facilitating diversity of experience remain important for supporting the health and wellbeing of dentists. Selling practices or, in the extreme, completely leaving the profession were considered practical options. At organisational level, building sustainable teams and transforming culture were advocated as important; while at systems level, reforming the NHS and bridging the gap between the profession and regulatory body were considered vital. Additionally, the need for strong professional leadership and wider societal debate was advocated as part of a whole systems approach to enable job satisfaction in delivering high-quality, patient-centred, evidence-based care in future.Conclusion While dentists demonstrated a range of coping mechanisms, multi-level action was advocated to enhance the health, wellbeing and retention of dentists. Systems reform at macro- and meso-levels is urgently advocated to enable fulfilling careers within dentistry, particularly for those at the front line of primary dental care in the public sector. Personal resilience alone will not suffice and recommendations for action are explored to avert a public health catastrophe. This is a time for reflection, debate and action.

Supporting dentists' health and wellbeing - workforce assets under stress: a qualitative study in England

Background Multiple determinants influence dentists' health and wellbeing. In light of recent concerns, the aim of this research was to explore contemporary influences on dentists' health and wellbeing in England, drawing on their lived experience.Methods Semi-structured interviews were conducted with a purposive sample of dentists working in England, taking into account age, gender, career stage, work sector, geographical area, position and route of entry to registration. A topic guide, informed by the literature, was used to guide the discourse. Dentists were approached via gatekeepers, supported by snowball sampling. Interviews were recorded and transcribed for analysis. Framework analysis was used, taking an interpretative phenomenological approach to develop theory.Results Twenty dentists, from a range of backgrounds, participated in this research. While health and wellbeing was reported to be more positive among dentists in their later career, those in their early career and/or with high NHS work commitments shared concerns about their physical, psychological and emotional health. Influences ranged from macro-level issues relating to professional regulation and health systems, through meso-level, notably their workplace and job specification, to micro-level issues relating to their professional careers, relationships and personal life. Dentists highlighted ethical concerns and feeling driven to deliver, together with being demoralised by a survival culture, all leading to perceived lack of control and reduced professional fulfilment. In contrast, being able to deliver quality care, innovate and effect change, as well as being valued for their delivery, were perceived to positively contribute to general health and wellbeing.Conclusion Dentists have a vital role in providing care for patients, so there are serious public health implications if urgent action is not taken to improve and sustain their health and wellbeing. This study confirms that dentists are affected by multiple contemporary influences, and although greater support is needed for individuals, organisational, system and policy changes may be required to fully address the challenges they face.

Protocol for A randomised feasibility trial comparing fluoride interventions to prevent dental decay in older people in care homes (FInCH trial)

BACKGROUND

The number and proportion of older people globally is growing faster than that of any other age group. At the same time the number of people retaining some of their own teeth is rising. There significant differences between those living in care and their community dwelling peers, with evidence showing those in care having fewer teeth and significantly higher levels of dental decay. There are numerous Cochrane reviews linking the use of fluoride to a reduction in dental decay, however, the majority of research on effectiveness has been conducted on children and consequently, children and adolescents tend to be the main recipients of fluoride interventions. There are to date no studies comparing the effectiveness of fluoride interventions in older people in care homes in the UK. However, prior to developing an appropriate protocol for full-scale trial comparing clinical effectiveness of fluoride interventions, there are a number of trial feasibility and statistical parameters that need to be clarified.

METHODS

This trial is a single centre, multi-site randomised controlled assessor blind parallel group (three groups) trial, with the primary objective of establishing the feasibility, practicability and compliance of fluoride interventions to prevent dental decay in care homes. Secondary and tertiary objectives will aim to explore the acceptability of the interventions from resident, care home and dental services perspectives, and estimate the efficacy of the three different fluoride treatments.

DISCUSSION

This feasibility trial will produce new knowledge and add value to a landscape that is under researched. Although the efficacy of fluoride interventions is proven, the feasibility of dental research and prevention in this vulnerable group and in the complex care home setting is novel. This work will not only add to our understanding of the interface of dental care and social care but will also contribute to our broader understanding on undertaking research in care home settings. Dental care for older people has been a longstanding issue, and the events of this past year has shone a light on the vulnerabilities of those residing in care homes and so this research is landing at a pivotal time.

Crisis in care homes: the dentists don't come

Aim/Objectives

To present the findings of the challenges relating to access to dental care for older people in care homes from the Fluoride Interventions in Care Homes (FInCH) Trial.

Methods

Thematic analysis of 11 interviews / focus groups with care home managers and care staff were carried out against a framework informed by the literature drawing on lived experiences.

Results

The challenges identified mapped to Penchanksy and Thomas’s (1981) five dimensions of access but also highlighted themes specifically relevant to the care home population. These include a lack of suitable services for routine and urgent domiciliary and clinic care, complex referral processes, operational challenges in the need for appropriate care chaperones, expectations of information for dental charge exemption and capacity / consent processes within the home.

Discussion

There is a malalignment of dental services offered to meet the needs of care home residents which has resulted in a reactive dental care system that is not fit for purpose and an entire generation of older people living in care with dental neglect.

Conclusion

Urgent action is needed to commission not only the appropriate quantities of both routine and urgent dental care, but ensure it is delivered by clinicians who are appropriately skilled to meet the high levels of dental needs in an increasingly medically and behaviourally complex care home population. In line with eye tests and prescribing at the very least, free routine dental examinations should be offered to all care home residents, creating the opportunity for advice and prevention, and enabling care home residents to function and be free of pain.

Reaching A Female Majority: A Silent Transition for Dentistry in the United Kingdom

This paper highlights the process of transition to a female majority for dentistry, examines various influences on this trajectory, and considers the implications for the profession, health systems and patients, as well as individual dentists.This celebratory transition has been facilitated by educational systems that provide both males and females with equal opportunities and is supported by legislation, as well as societal change that has spanned decades. In crossing this gender representation threshold, we have outperformed doctors nationally.In order to embrace our highly educated workforce and support them to better serve their patients and the population, urgent debate and action aimed at reshaping current systems of dental care provision are required. In this regard, flexible working arrangements, together with reshaping professional leadership to better represent the workforce, as well as changes in terminology can all play their part; however, we will need careful discussions about how this might happen effectively.A collaborative effort between the dental profession and wider health systems is required to ensure that there are opportunities for everyone to flourish and contribute back to the profession and society. Our medical counterparts have been considering how healthcare should be shaped creatively, particularly in relation to working patterns, economic models and quality patient care: we need to catch up.

Dental periodontal procedures: a systematic review of contamination (splatter, droplets and aerosol) in relation to COVID-19

INTRODUCTION

The emergence of the SARS-CoV-2 virus and subsequent COVID-19 pandemic has had a significant effect on the delivery of routine dentistry; and in particular, periodontal care across the world. This systematic review examines the literature relating to splatter, droplet settle and aerosol for periodontal procedures and forms part of a wider body of research to understand the risk of contamination in relation to periodontal care procedures relevant to COVID-19.

METHODS

A search of the literature was carried out using key terms and MeSH words relating to the review questions. Sources included Medline (OVID), Embase (OVID), Cochrane Central Register of Controlled Trials, Scopus, Web of Science and LILACS, ClinicalTrials.Gov . Studies meeting inclusion criteria were screened in duplicate and data extraction was carried out using a template. All studies were assessed for methodological quality and sensitivity. Narrative synthesis was undertaken.

RESULTS

Fifty studies were included in the review with procedures including ultrasonic scaling (n = 44), air polishing (n = 4), prophylaxis (n = 2) and hand scaling (n = 3). Outcomes included bacterial (colony-forming units e.g. on settle plates) or blood contamination (e.g. visible splatter) and non bacterial, non blood (e.g. chemiluminescence or coloured dyes) contamination. All studies found contamination at all sites although the contamination associated with hand scaling was very low. Contamination was identified in all of the studies even where suction was used at baseline. Higher power settings created greater contamination. Distribution of contamination varied in relation to operator position and was found on the operator, patient and assistant with higher levels around the head of the operator and the mouth and chest of the patient. Settle was identified 30 min after treatments had finished but returned to background levels when measured at or after an hour. The evidence was generally low to medium quality and likely to underestimate contamination.

CONCLUSION

Ultrasonic scaling, air polishing and prophylaxis procedures produce contamination (splatter, droplets and aerosol) in the presence of suction, with a small amount of evidence showing droplets taking between 30 min and 1 h to settle. Consideration should be given to infection control, areas of cleaning particularly around the patient and appropriate personal protective equipment, with particular attention to respiratory, facial and body protection for these procedures. In addition, the use of lower power settings should be considered to reduce the amount and spread of contamination.

Dental caries thresholds among adolescents in England, Wales, and Northern Ireland, 2013 at 12, and 15 years: implications for epidemiology and clinical care

BACKGROUND

Dental caries is the most prevalent condition globally. Despite improvements over the past few decades, there remains a significant disease burden in childhood. Epidemiological surveys provide insight to disease patterns and trends, and have traditionally focused on obvious decay which are inconsistent with contemporary clinical criteria. This study examined the distribution of dental caries in 12- and 15-year-olds in England, Wales and Northern Ireland, by severity threshold, at surface, tooth and child level and explored its association with socioeconomic, psychological and behavioural factors.

METHODS

Data from 12- and 15-year-olds in the 2013 Children's Dental Health Survey (CDHS 2013) were analysed at three levels, taking account of dental caries thresholds which involved recording both clinical decay [visual enamel caries (AV) and above] and obvious decay [non-cavitated dentine lesions (2V) and above]. Negative binomial regression was used to identify factors associated with dental caries experience at both thresholds.

RESULTS

The prevalence and severity of dental caries experience was higher among 15-year-olds at all levels. Visual change in enamel (AV) was by far the most common stage of caries recorded in both ages. The average number of surfaces with obvious decay experience, which has been the traditional epidemiological threshold, in 12- and 15-year-olds was 2.3 and 3.9 respectively. The corresponding values under the clinical decay threshold were higher, at 3.9 and 5.9 respectively. Visualisation of the distribution of dental caries at surface/tooth-level exhibited horizontal symmetry and to a lesser extent vertical symetry. In the adjusted models for both ages, country/region, school type, area deprivation, high frequency sugar consumption and irregular dental attendance were associated with greater caries experience in both groups. Dental anxiety was inversely associated with caries experience among 15-year-olds.

CONCLUSION

This research highlights the importance of recognising dental caries patterns by surface, tooth and child-level amongst adolescents and the value of reporting dental caries distribution by threshold in epidemiological surveys, including its relevance for clinical care. Inclusion of enamel caries reveals the extent of caries management required at a point when non-invasive care is possible, emphasising the importance of prevention through contemporary primary care, which includes supporting self-care.

Hashtag, like or tweet: a qualitative study on the use of social media among dentists in London

Aim To explore dentists' perceptions and use of social media generally and in relation to their professional careers, together with its implications for professionalism.Methods Semi-structured interviews were conducted with dentists in their early, mid- and late careers working in a range of settings based in London. Participants were purposively sampled via gatekeeper organisations, supported by snowball sampling. Interviews were audio-recorded, transcribed verbatim and data were analysed using thematic analysis.Results Eighteen dentists working across a range of career stages and care settings were interviewed. Participants were aware of the risks and benefits of using social media and expressed ways of balancing them. A typology of social media user types in the dental profession emerged from the data, comprising avoiders, secondary users, occasional users, observers, seekers, active and cautious, limited, engaged users and deleters. Participants reported an awareness of the impact of maintaining professionalism when using social media.Conclusion Among the participant population sampled, the risks and benefits of general and professional social media were discussed and, in some cases, these overlapped. The findings suggest that dentists are aware of the risks and benefits and employ techniques to balance risk. There were a range of social media user types that varied by characteristics, use in learning and the influences that change their use. It was evident that social media plays an important role in communication between those dentists engaging with available platforms. This area requires further research into professionalism and social media in dentistry.

Refocusing dental care: A risk-based preventative oral health programme for dentate older people in UK care homes

BACKGROUND

There is strong evidence for managing the risk of dental caries, notably dose-dependent use of fluoride based on risk. Specific guidance is lacking on higher fluoride use in older people in care homes and prevention is often omitted from dental care plans.

OBJECTIVES

To introduce a risk-based preventative approach to existing routine dental care for older people in care homes.

METHODS

Three mixed residential and nursing care homes for the frail and elder (>65 years) were selected to participate. All residents were risk assessed based on dependency, dentition status and self-care abilities and consequently placed on the appropriate evidence-based intervention (2800 ppm high dose fluoride toothpaste and/or quarterly fluoride varnish placement). Full mouth ICDAS dental examinations were completed at baseline, 6 months and 12 months.

RESULTS

At baseline, 127 risk assessments were completed in which most dentate residents (58.2%, n = 74) were assessed as Risk Level 2/3 (mod/high) whilst edentulous residents were all Risk Level 1 (low) (41.7%, n = 53). Only 13 (26.5%) of the 49 eligible residents completed the 12-month preventative programme. There was a significant difference in root caries (P < .0001), with 17 (51.5%) root lesions changing from active at baseline to arrested at 12 months.

CONCLUSIONS

The findings provide early indication of fluoride efficacy, especially on root caries in this vulnerable group, and highlight the challenges of delivering programme's in these complex, changing environments.

Hospital admissions for dental disorders in patients with severe mental illness in Southeast London: A register-based cohort study

In people with mental disorders, adverse general health is well recognized but dental diseases remain underinvestigated. The objective of this study was to investigate risk factors for hospital admissions for dental disorders in patients with severe mental illness (SMI) and/or depressive disorder. De-identified electronic mental health records from the South London and Maudsley NHS Foundation Trust (SLaM) were linked to national Hospital Episode Statistics (HES) data for analysis. Data were extracted for adults with a diagnosis of SMI (schizophrenia, schizoaffective disorder, bipolar disorder) and/or depression, who had received care at SLaM between 1 January 2010 and 31 March 2017. In the cohort of 18,999 patients thus obtained, the following factors were independently associated with hospital admission for dental disorders: female gender [odds ratio (OR) = 1.48, 95% CI: 1.31-1.68)], Health of the Nation Outcome Scales (HoNOS) problem drinking/drug taking (OR = 1.12, 95% CI: 1.05-1.19), HoNOS physical illness/disability (OR = 1.18, 95% CI: 1.12-.25), diabetes (OR = 1.24, 95% CI: 1.06-1.43), recorded current/past smoking (OR = 1.35, 95% CI: 1.06-1.43), treatment with antidepressant medication (OR = 1.48, 95% CI: 1.31-1.68), and depressive disorder (OR = 1.36, 95% CI: 1.11-1.68). Building on previous research in this population, which indicated a relatively high risk of acute care hospitalizations with dental disorders as discharge diagnoses, a number of demographic and clinical characteristics were found to be independent predictors over a 7-yr period. Further research into these predictors would facilitate a better understanding of how adverse dental outcomes might be prevented.

Dental caries experience and associated factors in adults: a cross-sectional community survey within Ethiopia

Background

Ethiopia is a developing sub-Saharan African country with increasing prevalence of non-communicable diseases (NCDs), including oral conditions. Oral health and dental care have been given little consideration, and there is limited information relating to population oral health and use of dental services in the country. The aim of this study was to examine the burden and associated factors of dental caries experience and investigate access to dental care amongst adults within Ethiopia.

Methods

This community-based oral health survey is a baseline study for the ASSET - Health System Strengthening in sub-Saharan Africa project undertaken in the Butajira area, south-central Ethiopia. A stratified random sample of households and individuals participated in the study. The survey instruments were mainly based on the WHO Oral Health Survey Methods manual (5^th ed.). Face-to-face interviews and clinical dental examinations were conducted. The data were analysed for descriptive statistics; and Poisson regression models were built to assess the association of dental caries and predictor variables in adults (≥18 years).

Results

Most of the study population (n = 626) were female (63.9%), married (71.4%) and Muslim (76.0%). Just over half (53.2%) lived in rural areas and many (44.4%) had no formal education. A majority (74.0%) reported never utilising dental care services, and the main reason was never experiencing any dental problem (71.3%). Sixty percent (n = 377) of the adults had experienced dental caries, 88.0% (n = 332) of whom had untreated carious teeth. Pain or discomfort was reported by 16.5, and 7.2% had one or more PUFA component. Most (59.9%) adults with dental caries experience reported tooth pain or discomfort during the last year. In the fully adjusted Poisson regression model, increasing age, dental care utilisation and Khat chewing had positive significant associations with dental caries experience, whilst education status was negatively associated (p < 0.05).

Conclusion

This study demonstrated a high burden of dental caries and considerable consequences resulting from untreated disease in this population of adults. There was evidence of social inequity, limited utilisation of dental care and oral health awareness. This highlights the need for oral health system strengthening focusing on health promotion and expanding overall access to care.

Developing a Standard Set of Patient-centred Outcomes for Adult Oral Health - An International, Cross-disciplinary Consensus

Objective

To develop a minimum Adult Oral Health Standard Set (AOHSS) for use in clinical practice, research, advocacy and population health.

Materials and methods

An international oral health working group (OHWG) was established, of patient advocates, researchers, clinicians and public health experts to develop an AOHSS. PubMed was searched for oral health clinical and patient-reported measures and case-mix variables related to caries and periodontal disease. The selected patient-reported outcome measures focused on general oral health, and oral health-related quality of life tools. A consensus was reached via Delphi with parallel consultation of subject matter content experts. Finally, comments and input were elicited from oral health stakeholders globally, including patients/consumers.

Results

The literature search yielded 1,453 results. After inclusion/exclusion criteria, 959 abstracts generated potential outcomes and case-mix variables. Delphi rounds resulted in a consensus-based selection of 80 individual items capturing 31 outcome and case-mix concepts. Global reviews generated 347 responses from 87 countries, and the patient/consumer validation survey elicited 129 responses. This AOHSS includes 25 items directed towards patients (including demographics, the impact of their oral health on oral function, a record of pain and oral hygiene practices, and financial implications of care) and items for clinicians to complete, including medical history, a record of caries and periodontal disease activity, and types of dental treatment delivered.

Conclusion

In conclusion, utilising a robust methodology, a standardised core set of oral health outcome measures for adults, with a particular emphasis on caries and periodontal disease, was developed.

A systematic review of droplet and aerosol generation in dentistry

OBJECTIVES

This review aimed to identify which dental procedures generate droplets and aerosols with subsequent contamination, and for these, characterise their pattern, spread and settle.

DATA RESOURCES

Medline(OVID), Embase(OVID), Cochrane Central Register of Controlled Trials, Scopus, Web of Science and LILACS databases were searched for eligible studies from each database's inception to May 2020 (search updated 11/08/20). Studies investigating clinical dental activities that generate aerosol using duplicate independent screening. Data extraction by one reviewer and verified by another. Risk of bias assessed through contamination measurement tool sensitivity assessment.

STUDY SELECTION

A total eighty-three studies met the inclusion criteria and covered: ultrasonic scaling (USS, n = 44), highspeed air-rotor (HSAR, n = 31); oral surgery (n = 11), slow-speed handpiece (n = 4); air-water (triple) syringe (n = 4), air-polishing (n = 4), prophylaxis (n = 2) and hand-scaling (n = 2). Although no studies investigated respiratory viruses, those on bacteria, blood-splatter and aerosol showed activities using powered devices produced greatest contamination. Contamination was found for all activities, and at the furthest points studied. The operator's torso, operator's arm and patient's body were especially affected. Heterogeneity precluded inter-study comparisons but intra-study comparisons allowed construction of a proposed hierarchy of procedure contamination risk: higher (USS, HSAR, air-water syringe, air polishing, extractions using motorised handpieces); moderate (slow-speed handpieces, prophylaxis, extractions) and lower (air-water syringe [water only] and hand scaling).

CONCLUSION

Gaps in evidence, low sensitivity of measures and variable quality limit conclusions around contamination for procedures. A hierarchy of contamination from procedures is proposed for challenge/verification by future research which should consider standardised methodologies to facilitate research synthesis.

CLINICAL SIGNIFICANCE

This manuscript addresses uncertainty around aerosol generating procedures (AGPs) in dentistry. Findings indicate a continuum of procedure-related aerosol generation rather than the common binary AGP or non-AGP perspective. The findings inform discussion around AGPs and direct future research to support knowledge and decision making around COVID-19 and dental procedures.

Everyday experiences of people living with dementia and their carers relating to oral health and dental care

Little is known about how community-dwelling people with dementia, as well as their carers, look after their oral health and use dental care. This exploratory study aimed to explore the beliefs, experiences and practices about oral health of people living with dementia and their carers. We used an ethnographic qualitative approach conducting face-to-face interviews at home with people living with dementia and/or carers. Interview data and field notes were analysed thematically using framework methods. We approached volunteers registered with the online UK. Join Dementia Research network from whom a total of 17 participants were recruited in 2018. Five interviews were conducted with carers alone, two with a person living with dementia alone, and five with a carer and person with dementia jointly. Three main themes emerged: oral health is not prioritised; access to dental care is shaped by increasing disability; and the importance of continuity of care. While people living with dementia and their carers may view oral health important once prompted, many reported difficulties in undertaking or assisting with daily self-care and accessing dental services, particularly as dementia progresses. We draw out implications for the organisation and delivery of public and private dental services.

Dental Public Health Education in Europe: a survey of European Dental Schools to determine current practice and inform a core undergraduate programme

OBJECTIVE

Describe current Dental Public Health [DPH] curricula content and delivery across European dental schools and ascertain views on a core undergraduate curriculum for dental students.

RESEARCH DESIGN

Survey of European dental schools, informed by professional and academic literature and European Association for Dental Public Health [EADPH] Special Interest Working Group discussions. Questionnaires were distributed electronically, by post, and via EADPH network members, to the Deans of 252 dental schools in Europe. E-mail reminders were sent to non-responders.

SETTING

European Dental Schools.

RESULTS

Around half (n=124, 49%) out of a possible 252 schools responded, all of which reported having some DPH education. Two-thirds reported having a dedicated DPH department. Education was delivered by a variety of staff including those trained in paediatric and preventive dentistry. There were differing degrees of integration within the undergraduate programme and substantial variability in topics, teaching methods and approaches to assessment. Key components of the curriculum supported by respondents were: DPH philosophy and approach, population demography and health, health promotion and disease prevention, health care systems, the dental workforce and planning for health and oral health. Respondents were generally in favour of improving current teaching and shaping a core DPH curriculum for Europe.

CONCLUSIONS

Amongst those who completed the questionnaire, there was a general agreement on the need for a core Dental Public Health curriculum for European dentists. Given the variation across Europe, increased awareness and prioritisation of the subject is required, facilitated by collaborative support.

Profiles of registrant dentists and policy directions from 2000 to 2020

Introduction

The National Health Service’s reliance on overseas doctors and nurses, unlike dentists, has been widely reported. As the United Kingdom (UK) leaves the European Union, an understanding of the migration trends and possible influences are important to inform future planning.

Aim

To examine trends in the profile of UK registered dentists in the context of key events and policy changes from 2000 to 2020.

Method

Data were obtained from the General Dental Council via annual reports, and under ‘freedom of information’ communications; details of policy initiatives were obtained from the government and professional websites.

Results

Over a 20-year period (2000–2019), the number of registered dentists increased from 31,325 to 42,469, a net increase of 36% (11,144 dentists), the majority of whom were international graduates (58%; n = 6,416) such that by December 2019, 28% of all registered dentists had qualified outside of the UK. Similarly, regarding new registrants, there were increases of graduates from UK (18%), EEA countries (214%) and, via the Overseas Registration Examination route (621%); and a decrease from countries with bilateral agreements for recognition (43%), in line with changes in health and immigration policies.

Conclusions

International dental graduates increasingly contribute to the UK dental workforce and there is an urgent need for research into dentist migration and retention in the UK in support of patient access to dental care.

Impact

The United Kingdom (UK) dental workforce is increasingly reliant on international dental graduates representing 28% of current registrants compared with 18% in 2000.

Health policies and immigration policies were the main drivers that influenced dental workforce migration to the UK along with wider events, such as EU expansions, global recession and Brexit.

Pre-existing lack of research into dental workforce could add to the uncertainties of post COVID-19 oral health care access and delivery.

A systematic review of contamination (aerosol, splatter and droplet generation) associated with oral surgery and its relevance to COVID-19

Introduction

The current COVID-19 pandemic caused by the SARS-CoV-2 virus has impacted the delivery of dental care globally and has led to re-evaluation of infection control standards. However, lack of clarity around what is known and unknown regarding droplet and aerosol generation in dentistry (including oral surgery and extractions), and their relative risk to patients and the dental team, necessitates a review of evidence relating to specific dental procedures. This review is part of a wider body of research exploring the evidence on bioaerosols in dentistry and involves detailed consideration of the risk of contamination in relation to oral surgery.

Methods

A comprehensive search of Medline (OVID), Embase (OVID), Cochrane Central Register of Controlled Trials, Scopus, Web of Science, LILACS and ClinicalTrials.Gov was conducted using key terms and MeSH (Medical Subject Headings) words relating to the review questions. Methodological quality including sensitivity was assessed using a schema developed to measure quality aspects of studies using a traffic light system to allow inter- and intra-study overview and comparison. A narrative synthesis was conducted for assessment of the included studies and for the synthesis of results.

Results

Eleven studies on oral surgery (including extractions) were included in the review. They explored microbiological (bacterial and fungal) and blood (visible and/or imperceptible) contamination at the person level (patients, operators and assistants) and/or at a wider environmental level, using settle plates, chemiluminescence reagents or air samplers; all within 1 m of the surgical site. Studies were of generally low to medium quality and highlighted an overall risk of contaminated aerosol, droplet and splatter generation during oral surgery procedures, most notably during removal of impacted teeth using rotatory handpieces. Risk of contamination and spread was increased by factors, including proximity to the operatory site, longer duration of treatment, higher procedural complexity, non-use of an extraoral evacuator and areas involving more frequent contact during treatment.

Conclusion

A risk of contamination (microbiological, visible and imperceptible blood) to patients, dental team members and the clinical environment is present during oral surgery procedures, including routine extractions. However, the extent of contamination has not been explored fully in relation to time and distance. Variability across studies with regards to the analysis methods used and outcome measures makes it difficult to draw robust conclusions. Further studies with improved methodologies, including higher test sensitivity and consideration of viruses, are required to validate these findings.

Migration, Retention and Return Migration of Health Professionals Comment on "Doctor Retention: A Cross-sectional Study of How Ireland Has Been Losing the Battle"

Medical education and training of health professionals are linked with their recruitment and retention. Practising as a competent health professional requires life-long continuous training and therefore training structures in health systems appear to influence doctors job satisfaction, their well-being and their intentions to remain in that health system. The commentary critiques aspects of the paper on doctors retention in Ireland, while drawing some parallels with the United Kingdom. There appears to be an emerging type of health professional migrants ‘education tourists’ who travel to other countries to obtain medical education creating new routes of migration and this presents new challenges to source and destination countries. The global shortage of doctors and other health professionals further exacerbates health inequalities as seen in the present pandemic and therefore the increased need for research into health professionals’ migration and their integration.

The dental workforce in Malaysia: drivers for change from the perspectives of key stakeholders

OBJECTIVE

The dental workforce is facing unprecedented change globally as a result of multiple influences. There is a need for research informed action to map possible drivers for change at the national level and examine their potential implications in order to shape the dental workforce to serve population needs. The objective of this study was to explore key stakeholders' views on the drivers for change for the Malaysian dental workforce and their potential implications.

METHOD

Stakeholders from key dental organisations/professions in Malaysia were purposively sampled and invited to participate in a semi-structured interview (n = 20) using a pre-tested topic guide. Interviews were recorded, transcribed verbatim and analysed using Framework Analysis.

RESULTS

Drivers for workforce were identified across four main domains: policy-politics; trends in demography; social and economic; and, technology-scientific development. The pace of change and possible interplay between drivers, most notably government policy, liberalisation of education and health services and challenges of workforce governance, followed by Malaysian demography and health trends. Implications for the future, including possible uncertainties, particularly in relation to specialisation and privatisation were identified, together in balancing and meeting public health needs/demands with professional career expectations.

CONCLUSION

Stakeholders' views on the high-level drivers for change broadly mirror those of high-income countries; however, specific challenges for Malaysia relate to rapid expansion of dental education and a young workforce with significant career aspirations, together with imbalances in the health care system. The impact of these drivers was perceived as leading to greatest uncertainty around specialisation and privatisation of the future workforce.

ADEA-ADEE Shaping the Future of Dental Education III: Engaging with global networking to enable global oral health

Global networking has been identified as an important method of enhancing health care education and services in the field of dentistry.¹ The ability to share expertise, resources, knowledge, and experience to benefit all is highly desired among students, educators, health care professionals, and communities globally. Both our student and patient populations are dynamic societies that are becoming increasingly complex and facing growing needs and expectations, which is a constant challenge for educators and health care professionals to satisfy.² The key question, stemming from the Global Networking (GN) workshop of the 2017 ADEE-ADEA Shaping the Future of Dental Education II meeting, was identified as, "How can dental educators around the world network to share ideas, experience, expertise, and resources to improve our curricula and teaching and learning environments for our educators, students, and communities that they serve?" The action plan devised by the GN workshop from the 2017meeting indicated two key steps in these early stages of setting up a global network: 1) "…grassroots participation for input and consumption of meaningful and needed content," and 2) "…advisors/consultants for organizational top-down guidance to define and maintain the global networking philosophy and platform…".¹ The GN workshop of 2019 SFDE meeting aimed to deliver guidance and discussion with those experienced in engaging local communities from both a grassroots and an organizational approach.

Diagnostic sensitivity and specificity of host-derived salivary biomarkers in periodontal disease amongst adults: Systematic review

OBJECTIVE

To systematically assess the diagnostic value of host-derived salivary biomarkers based on their reported sensitivity and specificity in relation to clinical parameters of periodontal disease diagnosis in adults.

MATERIALS AND METHODS

Comprehensive search of PubMed, Nature, Cochrane and OVID (Embase, MEDLINE [R] and PsycINFO) was conducted up to 1 August 2018, using key terms relevant to the research questions and Cochrane methodology, supplemented by a grey literature search. The revised Quality Assessment of Diagnostic Accuracy Studies (QUADAS- 2) tool was used to assess the methodological quality of all included studies.

RESULTS

Seven studies were included in the review. Macrophage inflammatory protein-1αlpha (MIP-1α), interleukin-1beta (IL-1β), interleukin-6 (IL-6) and matrix metalloproteinase-8 (MMP-8) were identified as diagnostically acceptable biomarkers for periodontal disease. Overall, the combination of IL-6 and MMP-8 showed best diagnostic performance. Also, a combination of the four key biomarkers (IL-1β, IL-6, MMP-8 and MIP-1α) showed promising results for distinction between gingivitis and periodontitis, as well as for periodontitis compared with gingival health. Results are interpreted with caution due to limitations in the number of studies included and their quality.

CONCLUSION

Certain salivary biomarkers can potentially be useful in combination and singularly for the diagnosis of periodontal disease. However, further methodically robust research is required to validate these biomarkers.

A Systematic Review and Meta-Analysis of the Role of Sugar-Free Chewing Gum in Dental Caries

OBJECTIVE

To determine the difference in level of dental caries in adults and children who chew sugar-free gum (SFG), compared with those who do not chew SFG or use alternatives such as lozenges, candies, rinses, tablets, and other nonchewing controls.

METHODS

Systematic review of published literature.

RESULTS

Twelve studies of interventions of SFG for dental caries outcomes were included. SFGs were found to significantly reduce caries increment, giving a preventative fraction (PF) of 28% (95% CI, 7% to 48%). Including the 8 trials that used xylitol gum only as the basis of the intervention, the PF was 33% (95% CI, 4% to 61%). No adverse effects were recorded. There was a high level of heterogeneity among the trials included.

CONCLUSION

The findings of this review provide tentative evidence that chewing SFG reduces caries increment in comparison to nonchewing controls. However, there is a considerable degree of variability in the effect and the trials included were generally of moderate quality. There is a need for future research to explore the acceptability and feasibility of the use of SFG as a public health intervention (PROSPERO 2018 CRD42018094676).

KNOWLEDGE TRANSFER STATEMENT

The results of this study can be used by clinicians when deciding how best to implement dental caries prevention regimes for their patients. With consideration of cost and patient preference, this information could help to develop national policy directives on caries prevention and dictate the direction of future clinical research.

Moving from advocacy to activism? The fourth WHO global forum on human resources for health and implications for dentistry

As we debate shaping the future oral health workforce within the UK, to meet the needs of current and future populations, it is helpful to take an international perspective on this very important issue. Globally, there is a strong recognition that human resources for health (HRH) are fundamentally important to deliver effective care, accessible to all people. This paper reviews the outcome of the fourth global forum held by the World Health Organisation (WHO) in Dublin which highlighted the urgency for action. The main objectives of the forum were to advance the implementation of (i) the WHO Global Strategy on HRH 2030 and (ii) the United Nations High-Level Commission's Health Employment and Economic Growth recommendations. From an oral health perspective, the global burden of oral disease remains huge with untreated dental caries, periodontal disease and tooth loss ranking among the most prevalent conditions worldwide. Major considerations are how dental education, practice delivery and/or oral health systems as a whole could and should innovate to accommodate the growing needs of the population. As dental professionals, it also becomes necessary for us to engage and play a proactive role in this change process. Due to growing differences between population needs and available services, it is necessary for oral health personnel to work more closely with the broader health workforce so as to identify solutions that are in the best interests of the patients and populations at large.

Clinical dental technicians in the United Kingdom: A qualitative understanding of the experiences, of practices and challenges of communication for dental professionals

AIM

To investigate the roles and relationships of registered Clinical Dental Technicians (CDTs) in the dental team and healthcare systems, and their perspective as a professional group in the United Kingdom (UK).

METHODS

This qualitative study was conducted following a national questionnaire survey of CDTs, 18 of whom participated in semi-structured interviews; they were purposively sampled to represent the diversity and demography of CDTs. A topic guide, informed by the literature and survey findings, guided discussions which were recorded and transcribed verbatim. Drawing upon phenomenological and cultural relativistic theories, thematic analysis was conducted, thus enabling an "analytic story" of the lived experience to emerge.

RESULTS

Clinical dental technicians expressed pride, passion and satisfaction in their work yet feel misunderstood in their role. Experiences of being accepted and incorporated into the wider dental profession are strained. Ultimately, there is a complex web of inter-dependence between all actors-a triadic relationship-bounded by policymakers and regulators which directly impacts on best practice and the balance between collaboration and autonomy. Looking to the future, Ideal practice may involve different models of care, with examples of good practice emerging.

CONCLUSION

This paper provides a unique examination of the lived experience, feelings and relationships of CDTs. The perceptions of their role, their inter-professional relations and the progression as a professional group must be addressed, and their potential to work collaboratively actively engaged to serve our ageing population.

A strife of interests: A qualitative study on the challenges facing oral health workforce policy and planning

Oral health workforce policy has often lacked systematic connections with broader health policy, and system-based reforms that would enable more effective responses to future needs of the population. The aim of the study was to better understand challenges facing oral health workforce policy and planning and identify potential solutions. In-depth interviews of 23 senior oral health leaders and/or health policy experts from 15 countries were conducted in 2016-17. Grounded theory principles using the Straussian school of thought guided the qualitative analysis. The findings identified: (i) narrow approach towards dental education, (ii) imbalances in skills, jobs and competencies, and (iii) geographic maldistribution as major challenges. An overarching theme -"strife of interests" - shed light on the tension between the profession's interest, and the needs of the population. A key aspect was the clash for power, dominance and authority within the oral health workforce and across health professions. This study argues that appreciating the history of health professions and recognising the centrality of the strife of interests is necessary in developing policies that both address professional sensitivities and are in line with the needs of the population. Integration and closer collaboration of oral health professionals with the mainstream medical and health professions has emerged as the key issue, but the solutions will be diverse and dependent on country- or context-specific scenarios.

Using Item Response Theory to evaluate the psychometric characteristics of questions in a Brazilian programme and the performance of dental teams in primary care

Objectives

First, to assess the psychometric properties of key questions included in a public sector evaluation of primary dental care in Brazil; and second, to evaluate the performance of dental teams in relation to these items.

Methods

Secondary analysis of a national primary care dataset monitoring quality and access to dental care. Data were collected through face-to-face interviews with representatives of dental teams participating in the ‘National Programme for Improving Access and Quality of Primary Care’. Twenty-three mandatory questions about the dentists’ reported delivery of dental procedures were included in the analysis. Item Response Theory (IRT) modelling was applied to measure the psychometric properties of the instrument—level of difficulty and discrimination parameter of each item—and then to estimate dental team performance scores based on these parameters. Based on IRT, possible scores ranged from -4 to +4.

Results

Three of the 23 mandatory items were removed due to poor internal consistency, resulting in a scale of 20 items for assessing dental team performance. The results showed variation in procedures delivered by the dental teams; whilst more than a half of the procedures were executed by at least 80% of the dental teams, those relating to dentures (partial/total) and frenectomy (lingual/labial) were performed by less than 30%. Amongst the 20 items included in the model, those related to partial/total dentures and oral cancer follow-up presented higher levels of difficulty and were less frequently provided. The items relating to the treatment of deciduous teeth and access to the dental pulp of permanent teeth had the highest discrimination parameters and, consequently, greater weight in the performance’s score estimation; therefore, dental teams that did not perform these items had the lowest performance scores. In the present study, dental team performance scores ranged from -3.66 to +1.87 with a mean/median of -0.06/+0.01.

Conclusion

The findings suggest that whilst the items within the instrument demonstrated some potential to discriminate between poor and very poor teams, they were ineffective in discriminating between poor and good teams. Whilst Brazilian dental teams perform many mandatory procedures, variation in the nature of their delivery of care requires further investigation to enhance service provision to the population.

Electronic primary dental care records in research: A case study of validation and quality assurance strategies

BACKGROUND

In dentistry, the use of electronic patient records for research is underexplored. The aim of this paper is to describe a case study process of obtaining research data (sociodemographic, clinical and workforce) from electronic primary care dental records, and outlining data cleaning and validation strategies. This study was undertaken at the University of Portsmouth Dental Academy (UPDA), which is a centre of education, training and provision of state funded services (National Health Services). UPDA's electronic patient management system is R4/Clinical +. This is a widely used system in general dental practices in the UK.

METHOD

A two-phase process, involving first Pilot and second Main data extraction were undertaken. Using System Query Language (SQL), data extracts containing variables related to patients' demography, socio-economic status and dental care received were generated. A data cleaning and validation exercise followed, using a combination of techniques including Maletic and Marcus's (2000) general framework for data cleaning and Rahm and Haido's (2010) principles of data cleaning.

RESULTS

The findings of the case study support the use of a two-phase data extraction process. The data validation processes highlighted the need for both manual and analytical strategies when cleaning these data. Finally, the process demonstrated that electronic dental records can be validated and used for epidemiological and heath service research. The potential to generalise findings is great due to the large number of records. There are, however, limitations to the data which need to be considered, relating to quality (data input), database structure and interpretation of data codes.

CONCLUSION

Electronic dental records are useful in health service research, epidemiological studies and skill mix research. Researchers should work closely with clinicians, managers and software developers to ensure that the data generated are accurate, valid and generalisable. Following data extraction the researchers need to adapt stringent validation and data cleaning strategies to guarantee that the extracted electronic data are accurate.
