Global oral health inequalities: task group--implementation and delivery of oral health strategies

Impact of an oral care subsidization reform on intersectional inequities in self-rated oral health in Sweden

BACKGROUND

Oral health in Sweden is good at the population level, but seemingly with persisting or increasing inequities over the last decades. In 2008, a major Swedish reform introduced universal partial subsidies to promote preventive care and reduce the treatment cost for patients with extensive care needs. This study aimed to apply an intersectional approach to assess the impact of the 2008 subsidization reform on inequities in self-rated oral health among adults in Sweden over the period 2004-2018.

METHODS

Data from 14 national surveys conducted over 2004-2018 were divided into three study periods: pre-reform (2004-2007), early post-reform (2008-2012) and late post-reform (2013-2018). The final study population was 118,650 individuals aged 24-84 years. Inequities in self-rated oral health were examined by intersectional analysis of individual heterogeneity and discriminatory accuracy across 48 intersectional strata defined by gender, age, educational level, income, and immigrant status.

RESULTS

Overall, the prevalence of poor self-rated oral health decreased gradually after the reform. Gender-, education- and income-related inequities increased after the reform, but no discernible change was seen for age- or immigration-related inequities. The majority of intersectional strata experienced patterns of persistently or delayed increased inequities following the reform.

CONCLUSIONS

Increased inequities in self-rated oral health were found in most intersectional strata following the reform, despite the seemingly positive oral health trends at the population level. Applying an intersectional approach might be particularly relevant for welfare states with overall good oral health outcomes but unsuccessful efforts to reduce inequities.

Evaluation of an early childhood caries preventive programme starting during pregnancy-Results after 3 and 6 years

BACKGROUND

Early childhood caries (ECC) has been found to be up to five times more common among children living in areas of low socio-economic status (SES) than among children in areas of higher SES.

AIM

To evaluate an ECC prevention programme from pregnancy to 3 and 6 years of age.

DESIGN

A prospective, controlled, intervention cohort study was initiated in 2013 in a low-SES area in Sweden. The intervention group received an individual interdisciplinary ECC prevention programme starting pre-birth, consisting of supportive oral health-promoting talks using motivational interviewing techniques and individual ECC preventive actions. A control group, consisting of pregnant women living in a comparable area, received ordinary routines.

RESULTS

Of the 336 pregnant women, 64 mothers (with 64 children) completed the programme, and 394 children were born in the control group. At the sixth year examination, the proportion of children with no caries was similar between the groups (53% resp. 52%, p = .976), whereas the proportion with decayed, missed, filled primary teeth (dmft = 1-5) was slightly lower (23% resp. 36%, p = .063), and the proportion with severe caries disease (dmft > 5) was higher (p = .013) in the intervention group (25%) than in the control group (12%).

CONCLUSION

No preventive effect regarding caries can be demonstrated at sixth year of age. Maternal behavioural change in dental care was not sufficient to even out inequalities in oral health in children, eventually due to difficulties in reaching the target group and the lack of effects among the families reached.

Cultural factors and family influences on adolescent oral health: qualitative research in a socially disadvantaged population

AIM

This qualitative study sought to assess the influence of cultural factors and family on oral health behaviour of 12- to 15-year-old adolescents from the socially disadvantaged population.

DESIGN

A qualitative design was developed with focus group discussions (FGDs) among 12- to 15-year-old adolescents. Four focus groups (n = 32 participants) were created from a selected sample to capture oral health beliefs and practices, oral health-seeking behaviour along with other relevant information. Focus group discussions were audio-recorded, transcribed verbatim and translated. Data were analysed thematically and structural coding was applied.

RESULTS

Three key themes that emerged from FGDs were importance of oral health; role of family in oral health behaviour; and beliefs influencing access, prevention and treatment of oral diseases. Cultural background, family values and beliefs were imperative in moulding the behaviour of adolescents towards oral health. The use of traditional oral hygiene aides was a norm in this population.

CONCLUSIONS

Findings of the study provide greater insights into the authoritative role of family and cultural barriers in the uptake of dental services. The study also highlights the potential value of qualitative research and emphasizes the need to integrate oral health-associated cultural beliefs and attitudes of the adolescents towards a wider evidence base.

Dental caries and associated factors in 7-, 12- and 15-year-old schoolchildren in the canton of Basel-Landschaft, Switzerland: Changes in caries experience from 1992 to 2021

BACKGROUND

Epidemiological surveys in schoolchildren are used to assess the current status of oral health.

AIM

To investigate the changes in caries experience among schoolchildren in the canton of Basel-Landschaft, Switzerland, over a period of three decades. Secondary objectives were to evaluate the impact of various personal and demographic factors such as age group, place of residence or dental hygiene awareness on caries prevalence as well as the history of orthodontic treatment in the year 2021.

DESIGN

A random sampling of school classes from first, sixth and ninth grades, that is schoolchildren aged 7, 12 and 15 years, was performed. Children's dmft and DMFT scores were determined according to the WHO methodology while information on oral hygiene habits and dental prophylaxis awareness was collected by means of a questionnaire directed to the legal guardians of the children. Individual logistic regressions were performed to identify possible influencing factors for caries.

RESULTS

A total of 1357 schoolchildren could be included in the study. In the year 2021, the youngest age group had an average of 0.68 primary teeth that needed treatment, whereas the 12- and 15-year-olds each had approximately 0.3 permanent teeth requiring treatment. While these numbers remained constant over the examination period of three decades, most of the other caries indices improved. Younger children (p = .001) and children with a migrant background (p < .001) were found to be risk groups. Orthodontic treatment was more frequent in females, schoolchildren of Swiss nationality and children attending higher secondary schools at ninth grade.

CONCLUSION

This study demonstrated that even in a country with a low prevalence of caries experience, untreated carious lesions remain a problem as their prevalence remained unchanged over the examination period of three decades.

Formulation and antibacterial properties of lollipops containing of chitosan- zinc oxide nano particles on planktonic and biofilm forms of Streptococcus mutans and Lactobacillus acidophilus

This study aimed to formulate and characterize the experimental lollipops containing chitosan- zinc oxide nanoparticles (CH-ZnO NPs) and investigate their antimicrobial effects against some cariogenic bacteria. The CH-ZnO NPs were synthesized and characterized by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) analysis, and Transmission electron microscope (TEM). Then, four groups were made, including lollipops coated with 2 and 4 ml of CH-ZnO NPs, 0.7 ml CH-ZnO NPs incorporated lollipops, and those with no CH-ZnO NPs. Their antibacterial effectiveness against Streptococcus mutans and Lactobacillus acidophilus was evaluated by direct contact test and tissue culture plate method in planktonic and biofilm phases, respectively. Chlorhexidine mouthrinse (CHX) was used as a positive control group. In the planktonic phase, the antibacterial properties of both groups coated with CH-ZnO NPs were comparable and significantly higher than incorporated ones. There was no significant difference between CHX and the lollipops coated with 4 ml of NPs against S. mutans and CHX and two coated groups against L. acidophilus. None of the experimental lollipops in the biofilm phase could reduce both bacteria counts. The experimental lollipops coated with 2 and 4 ml of CH-ZnO NPs could reveal favorable antimicrobial properties against two cariogenic bacteria in the planktonic phase.

Oral health-related stigma: Describing and defining a ubiquitous phenomenon

This paper is the fourth of a series of narrative reviews to critically rethink underexplored concepts in oral health research. The series commenced with an initial commissioned framework of Inclusion Oral Health, which spawned further exploration into the social forces that undergird social exclusion and othering. The second review challenged unidimensional interpretations of the causes of inequality by bringing intersectionality theory to oral health. The third exposed how language, specifically labels, can perpetuate and (re)produce vulnerability by eclipsing the agency and power of vulnerabilised populations. In this fourth review, we revisit othering, depicted in the concept of stigma. We specifically define and conceptualize oral health-related stigma, bringing together prior work on stigma to advance the robustness and utility of this theory for oral health research.

Is childhood oral health the 'canary in the coal mine' for poor adult general health? Findings from two New Zealand birth cohort studies

OBJECTIVES

This study aimed to investigate whether childhood dental caries was associated with self-reported general health in midlife.

METHODS

We used data on childhood oral health (caries experience) and adult self-reported general health from two New Zealand longitudinal birth cohorts, the Dunedin Multidisciplinary Health and Development Study (n = 922 and n = 931 at ages 5 and 45 years, respectively), and the Christchurch Health and Development Study (n = 1048 and n = 904 at ages 5 and 40 years, respectively). We used generalized estimating equations to examine associations between age-5 dental caries and self-rated general health and the number of self-reported physical health conditions at ages 45/40 (diagnosed by a doctor or health professional, n = 14 conditions among both cohorts). Covariates included known risk factors for poor health (SES, IQ, perinatal complications), and personality style, which is known to affect subjective health ratings.

RESULTS

Incidence rate ratios for 'Excellent' self-rated health were lower among those who had high experience of dental caries as children than those who had not in both, the Dunedin (IRR, 0.76; 95% CI, 0.50, 1.14) and Christchurch studies (IRR, 0.69; 95% CI, 0.47, 1.00). Childhood dental caries was not associated with the number of self-reported physical health conditions in midlife, in either cohort. Dunedin Study members who at age 5 were not caries-free or whose parents rated their own or their child's oral health as poor were less likely to report 'Excellent' self-rated general health at age 45 than those who were caries-free and whose parents did not give a 'poor' rating (IRR, 0.69; 95% CI, 0.49, 0.97).

CONCLUSIONS

Five-year-olds with greater caries experience were more likely to have poorer self-rated general health by midlife. Beyond this longitudinal association, future research should examine whether childhood dental caries is associated with objective/biological markers of physical health and whether it may have utility as an early indicator for poor general health in adulthood.

Oral Health Strategies: Surveying the Present to Plan the Future of Community-Based Learning

Introduction: Oral health literacy relates to the capacity of individuals to acquire, understand and to act upon oral health information to make appropriate health decisions. This scientific review's main goal is to analyze the strategies that improve oral health literacy within the community, specifically oriented to a community-based learning model focused on the most vulnerable risk groups in society. Materials and Methods: The current review is based on the literature on oral health literacy within community-based learning strategies. The present review selected scientific studies by searching MEDLINE and related databases, such as Web of Science and PUBMED, and by consulting existing bibliographies. Results: Based on the application of the inclusion criteria to the abstracts, 45 publications were retrieved which explicitly dealt with the definitions of oral health literacy, community-based learning, and service learning. Several studies have demonstrated that health consumers with low health literacy fail to understand the available health information. Therefore, innovative oral health literacy strategies should be undertaken. Service learning is an example of an educational approach where the student learns specific soft skills in the classroom and collaborates directly with an agency or institution and engages in reflection activities to deepen their understanding of what is being taught. Conclusions: One of the main strategies used to incorporate the oral health professional in social responsibility and direct contact in the community is through experiencing community-based learning projects. The future graduate must be an educator capable of educating patients in order to themselves acquire high-level skills in oral health literacy.

Untreated dental caries among Libyan children during and after the war and in internally displaced person camps

OBJECTIVES

The present study assessed whether living in a conflict zone and in internally displaced person (IDP) camps were associated with the number of untreated caries in primary, permanent and all teeth in Libyan children and whether these associations differed by parents' educational attainment.

METHODS

Cross-sectional studies were conducted in Benghazi, Libya, in 2016/2017 during the war and in 2022 after the war including children in schools and in IDP camps in the same setting. Self-administered questionnaires and clinical examinations were used for data collection from primary schoolchildren. The questionnaire collected information on children's date of birth, sex, level of parental education and school type. The children were also asked to report on how often they consumed sugary drinks and whether they brushed their teeth regularly. In addition, untreated caries in primary, permanent and all teeth were assessed according to World Health Organization criteria at the dentine level. Multilevel negative binomial regression models were used to assess the relation between dependent variables (untreated caries in primary, permanent and all teeth) and living environment (during and after the war and living in IDP camps) and parental educational attainment adjusted for oral health behaviours and demographic factors. The modifying effect of parental educational attainment (no, one and both parents university educated) on the association between living environment and the number of decayed teeth was also assessed.

RESULTS

Data were available from 2406 Libyan children, 8-12 years old (mean = 10.8, SD = 1.8). The mean (SD) number of untreated decayed primary teeth was 1.20 (2.34), permanent teeth = 0.68 (1.32) and all teeth = 1.88 (2.50). Compared to children living in Benghazi during the war, children living in the city after the war had significantly greater number of decayed primary (adjusted prevalence ratio [APR] = 4.25, p = .01) and permanent teeth (APR = 3.77, p = .03) and children in IDP camps had significantly greater number of primary teeth (APR = 16.23, p = .03). Compared to children whose both parents were university-educated, those with no university-educated parents had a significantly greater number of decayed primary teeth (APR = 1.65, p = .02) and significantly less number of decayed permanent (APR = 0.40, p < .001) and all teeth (APR = 0.47, p < .001). There was a significant interaction between parental education and living environment in the number of all decayed teeth in children who lived in Benghazi during the war: children whose both parents were non-university-educated had significantly less number of all decayed teeth (p = .03) with no interaction effect in those living in Benghazi after the war or in IDP camps (p > .05).

CONCLUSION

Children living in Benghazi after the war had more untreated decay in primary and permanent teeth than children during the war. Having parents with no university education was associated with greater or less untreated decay depending on the dentition. These variations were most pronounced among children during the war in all teeth with no significant differences in after-war and IDP camps groups. Further research is required to understand how living in war environment influenced oral health. In addition, children affected by wars and children living in IDP camps should be identified as target groups for oral health promotion programs.

Barriers to prevention in oral health care for english NHS dental patients: a qualitative study of views from key stakeholders

BACKGROUND

Despite significant progress in the control of oral diseases since the discovery of fluoride in the 1940s, dental caries and periodontal diseases continue to affect a significant proportion of the population, particularly socially disadvantaged and lower socioeconomic groups. The National Health Service in England provides preventive advice and treatments as part of an oral health assessment, and evidence-based guidance recommends the use of fissure sealants and topical fluorides in addition to dietary and oral hygiene advice. Although oral health promotion and education have become expected parts of dental care, the need for restorative treatments remains relatively high. We aimed to explore how barriers to preventive advice and treatment for NHS patients may be hindering the provision of prevention in oral health to patients from the perspectives of multiple key stakeholders.

METHODS

Semi-structured interviews and focus groups were undertaken between March 2016-February 2017 with four groups of stakeholders: dentists, insurers, policy makers and patient participants. The interviews were analysed using deductive, reflexive thematic analysis.

RESULTS

Thirty-two stakeholders participated: 6 dentists, 5 insurers, 10 policy makers, and 11 patient participants. Four themes were developed: Perspectives on the clarity of oral health messaging and patient's knowledge, The variability of prioritising prevention, Influences of the dentist-patient relationship on effective communication and Motivation to enact positive oral health behaviours.

CONCLUSIONS

The findings from this research indicate that patients' knowledge of and priority placed on prevention is variable. Participants believed that more targeted education could be valuable in enhancing these. A patient's relationship with their dentist could also influence their level of knowledge through the information shared with them, their receptivity to the preventive messages and the value they place on it. However, even with knowledge, prioritising prevention and a good patient-dentist relationship, without motivation to engage in preventive behaviour the impact of these is reduced. Our findings are discussed in relation to the COM-B model of behaviour change.

Measuring oral health-How can the International Classification of Functioning help?

There is a need for a theoretically informed, contextualized approach to measuring oral health from a multidisciplinary perspective that goes beyond the commonly used clinical indices and sociodental measures. This commentary aims to discuss the potential for the WHO's International Classification of Functioning, Disability and Health (ICF) to provide a model for the development of indicators for oral health. It is suggested that the ICF might provide both a theoretical model and an operational classification for indicators of oral health. The ICF model states that human experience of physical, cognitive and social functioning is universal and, thus, can be described and qualified. Human function is given social and environmental context within the model at both an individual and population level. The ICF can not only capture data regarding oral health and function at the physiological level (e.g. chewing) but also at the social level (e.g. sharing meals). It is able not only to capture aspects of preventive behaviour (e.g. caring for teeth) but also aspects of social facilitation (e.g. economic self-sufficiency) or ability to fulfil a social role (e.g. remunerative employment). It also includes aspects of social environment, such as healthcare services or political, economic and legal systems. Case studies are given as examples of the potential use of the ICF in the oral health domain. Examples are also given of the first steps that have been made towards operationalization of the ICF in data collection and oral health research. The challenges of encompassing such a comprehensive model into a practical oral health measure are discussed.

Barriers and facilitators to dental care among culturally and linguistically diverse carers: A mixed-methods systematic review

OBJECTIVES

Culturally and linguistically diverse (CALD) communities experience widespread inequalities in dental care utilization. While, several studies have reported factors contributing to such inequalities, a synthesis of evidence is lacking for CALD carers. This review examined the barriers and facilitators to dental care utilization among CALD carers.

METHODS

Medline, CINAHL, ProQuest, Scopus and Web of Science were searched for dental utilization and related factors, without geographic limitations. An integrated mixed-method design was adopted, where both qualitative and quantitative findings were combined into a single synthesis. Critical appraisal was conducted using JBI tools, and a Universal Health Coverage (UHC) framework guided the synthesis approach. Reliability and researcher triangulation occurred throughout the conduct of this review.

RESULTS

A total of 20 papers were included: qualitative (n = 8), quantitative (n = 8) and mixed method (n = 4). Studies were from Australia, Canada, South Korea, Trinidad and Tobago, United Kingdom and the United States. Three studies insufficiently reported confounding variables and nine qualitative papers lacked philosophical perspectives. Affordability was the foremost barrier at the system level, followed by psychosocial negative provider experiences and language/communication issues at the provider level. Cultural, knowledge, attitudes and beliefs were individual-family level factors. Utilizing a UHC framework, the barriers and facilitators were aggregated at three levels; financial-system, provider and individual-family levels and illustrated in the rainbow model of CALD oral health.

CONCLUSION

The review strengthens evidence for multilayered, system-related policies and culturally sensitive provision of services for reducing oral healthcare inequalities in CALD carers.

Association between cash transfer programs and oral health-A scoping review

OBJECTIVES

The aims of this scoping review are to assess the literature investigating the association between cash transfer programs and oral health; and to identify the theoretical frameworks applied to guide this literature.

METHODS

A search strategy to identify studies published until December 2020 was applied to a range of databases. Observational and interventional studies that had cash transfer programs as exposure/intervention and oral health as outcome were considered. Dental health services utilization, as well as access to dental health services, were considered secondary outcomes. Cash transfer programs were considered programs based on conditional or unconditional cash transfer carried out as part of national social protection schemes, and interventional studies on the impact of cash transfer on oral health were also considered eligible. Data charting was performed in two steps and a narrative synthesis was conducted.

RESULTS

Of 6344 articles identified, four articles were included. These articles investigated three different conditional cash transfer programs, Universal Child Allowance (Argentina), Bolsa Família (Brazil) and Family Rewards (USA). Inconsistencies were identified in findings on the effect of conditional cash transfer programs on the prevalence of dental caries and these differences may be due to the comparison group selected for each study. Concerning dental visits, the results point in different directions, which makes these findings still inconclusive. No explicit theoretical framework was reported in the articles to guide the expected association.

CONCLUSION

Although cash transfers play an important role in improving certain health outcomes, there is limited evidence to suggest an association between cash transfers and oral health.

Clustering of Health and Oral Health-Compromising Behaviours in Army Personnel in Central Peninsular Malaysia

Health- and oral health-compromising behaviours (HOHCBs) impact the health readiness of military personnel, resulting in decreased fitness performance, thus affecting combat readiness. This study aimed to identify the clustering patterns and number of HOHCBs in army personnel in Central Peninsular Malaysia. Thus, a cross-sectional study using a multistage sampling technique and a validated 42-item online questionnaire was conducted to assess ten health (medical screening, physical activity, sedentary lifestyle, smoking status, alcohol consumption, substance abuse, aggressive behaviours, sleep, and road safety habits) and five oral health behaviour domains (tooth brushing, fluoridated toothpaste use, flossing, dental visits, and bruxism). Each HOHCB was dichotomised into healthy and health-compromising behaviour and analysed using hierarchical agglomerative cluster analysis (HACA). With the majority being males (92.5%), of other ranks (96.8%), and healthy (83.9%), 2435 army members of a mean age of 30.3 years (SD = 5.9) participated, with a response rate of 100%. HACA identified two clustering patterns: (i) 'high-risk behaviours' (30 HOHCBs) and (ii) 'most common risk behaviours' (12 HOHCBs) with a mean clustering number of 14.1 (SD = 4.1). In conclusion, army personnel in Central Peninsular Malaysia displayed 2 broad HOHCB clustering patterns, 'high-risk' and 'most common risk', with an average of 14 HOHCB clusters per person.

The Impact of Dental Care Programs on Individuals and Their Families: A Scoping Review

BACKGROUND

Despite significant global improvements in oral health, inequities persist. Targeted dental care programs are perceived as a viable approach to both improving oral health and to address inequities. However, the impacts of dental care programs on individual and family oral health outcomes remain unclear.

OBJECTIVES

The purpose of this scoping review is to map the evidence on impacts of existing dental programs, specifically on individual and family level outcomes.

METHODS

We systematically searched four scientific databases, MEDLINE, EMBASE, CINAHL, and Sociological Abstracts for studies published in the English language between December 1999 and November 2021. Search terms were kept broad to capture a range of programs. Four reviewers (AG, VD, AE, and KKP) independently screened the abstracts and reviewed full-text articles and extracted the data. Cohen's kappa inter-rater reliability score was 0.875, indicating excellent agreement between the reviewers. Data were summarized according to the PRISMA statement.

RESULTS

The search yielded 65,887 studies, of which 76 were included in the data synthesis. All but one study assessed various individual-level outcomes (n = 75) and only five investigated family outcomes. The most common program interventions are diagnostic and preventive (n = 35, 46%) care, targeted children (n = 42, 55%), and delivered in school-based settings (n = 28, 37%). The majority of studies (n = 43, 57%) reported a significant improvement in one or more of their reported outcomes; the most assessed outcome was change in dental decay (n = 35).

CONCLUSIONS

Dental care programs demonstrated effectiveness in addressing individual oral health outcomes. However, evidence to show the impact on family-related outcomes remains limited and requires attention in future research.

Barriers to dental care in a rural community

PURPOSE

A nurse-led rural practice, Archer Family Health Care, established a partnership with the University of Florida College of Dentistry to improve access to dental care for underserved rural populations. The purpose of this project was to evaluate the impact of this partnership on dental care access and identify perceived barriers patients' experience in this rural community.

METHODS

A qualitative design was used to evaluate if this partnership improved access to dental care and identify care barriers existing in this population. Outcome measures were 1) completed dental visits and 2) a qualitative analysis of patients' perceived barriers to accessing care if they did not complete their dental appointment.

RESULTS

As a result of this partnership, 118 direct dental referrals were placed. From those referrals, 45 (38%) patients completed their dental appointments, and 73 (62%) patients did not. Twenty-five patients provided a rationale for not presenting for their appointment. Cited barriers included cost (32%), time (24%), frustration with the referral process (20%), obtaining care at an alternate dental location (12%), fear (7%), and transportation issues (4%).

CONCLUSION

This project suggests that specific interventions may increase opportunities for dental care in rural areas however barriers continue to exist that may impact that access.

Translation and cultural adaptation of the Illness Perception Questionnaire-Revised for Dental to Brazil

This study aimed to translate and to perform the cultural adaptation of the instrument Illness Perception Questionnaire-Revised for Dental (IPQ-RD) into Brazilian Portuguese. The IPQ-RD consists of 34 items that assess the cognitive and emotional representation/perception of parents/caregivers of children with dental caries, with response options on a 5-point Likert scale, ranging from "Strongly agree" (score 1) to "Strongly disagree" (score 5). The higher the score, the lower the perception of the disease. The protocol consists of translation into Brazilian Portuguese, back-translation into English, revision by an Expert Review Committee, and pre-test (application in parents/caregivers of children in dental care). For some questions, the translated versions were identical (T1 = T2); for others, one version was preferred (T1 or T2); for still others, it was decided to modify terms to obtain greater clarity on the item (T3). In the first pre-test, three questions were misunderstood by more than 15% of the sample, after which the items were reviewed by the Expert Review Committee. In the second pre-test, the adapted version was applied to a new sample of parents/caregivers (n = 15) and the questions were understood by more than 85% of the participants. The Brazilian Portuguese version of the IPQ-RD was well understood by the evaluated population.

Professionals’ perspectives on how to address persistent oral health inequality among young children: an exploratory multi-stakeholder analysis in a disadvantaged neighbourhood of Amsterdam, the Netherlands

Background

Oral health promotion interventions have had limited success in reaching families in disadvantaged neighbourhoods resulting in persistent oral health inequality. This qualitative study provides insight into professionals’ perspectives on children’s poor oral health (≤ 4 years), their perceptions of the roles and responsibilities, and opportunities for child oral health promotion strategies.

Methods

Thirty-Eight professionals from different domains (community, social welfare, general health, dental care, public health, private sector) working in a disadvantaged neighbourhood in Amsterdam, the Netherlands, participated through 24 semi-structured (group) interviews. Transcripts and notes were analysed through thematic analysis.

Results

Professionals indicate that unhealthy diet, children’s non-compliance, poor parental coping, parental low oral health literacy, parent’s negative attitude, family’s daily struggles, and insufficient emphasis on childhood caries prevention in dental practices, general healthcare and social welfare organisations, underlie poor oral health. They hold parents most responsible for improving young children’s oral health, but recognise that families’ vulnerable living circumstances and lack of social support are important barriers. Interestingly, non-dental professionals acknowledge their beneficial role in child oral health promotion, and dental professionals stress the need for more collaboration.

Conclusion

A broad child-, parental-, and societal-centred educational communication strategy is perceived as promising. Professionals working within and outside the dental sector acknowledge that local and collective action is needed. This involves a better understanding of family’s complex daily reality. Furthermore, intensifying child oral health knowledge in dental practices is essential in collaboration with families, general health and social welfare organisations.

Magnetism in Dentistry: Review and Future Perspectives

Tissue engineering or tissue reconstruction/repair/regeneration may be considered as a guiding strategy in oral and maxillofacial surgery, as well as in endodontics, orthodontics, periodontics, and daily clinical practice. A wide range of techniques has been developed over the past years, from tissue grafts to the more recent and innovative regenerative procedures. Continuous research in the field of natural and artificial materials and biomaterials, as well as in advanced scaffold design strategies has been carried out. The focus has also been on various growth factors involved in dental tissue repair or reconstruction. Benefiting from the recent literature, this review paper illustrates current innovative strategies and technological approaches in oral and maxillofacial tissue engineering, trying to offer some information regarding the available scientific data and practical applications. After introducing tissue engineering aspects, an overview on additive manufacturing technologies will be provided, with a focus on the applications of superparamagnetic iron oxide nanoparticles in the biomedical field. The potential applications of magnetic fields and magnetic devices on the acceleration of orthodontic tooth movement will be analysed.

Influence of socioeconomic status on oral disease burden: a population-based study

Background

Dental caries is associated with Biological, behavioral, socioeconomic, and environmental factors; however, socioeconomic status is a distal determinant of dental caries development that modulates exposure to risk and protective factors. This study aimed to analyze the socioeconomic factors associated with the concentration of oral diseases in a population-based study in Brazil.

Methods

This is a quantitative, analytical, cross-sectional study based on secondary data from the SB São Paulo 2015 epidemiological survey. A total of 17,560 subjects were included. The concentration of oral disease in the population was estimated by the oral disease burden (ODB) variable. The ODB consists of four components: dental caries; tooth loss; need for dental prosthesis and periodontal condition. Thus, the total score on the ODB could vary between 0 and 4, with the highest score indicating the worst possible situation. ODB was analyzed in multivariate negative binomial regression, and multivariate binary logistic regression analysis. The following factors were included as independent variables: age group, skin color, socioeconomic factors, family income and Oral Impact on Daily Performance (OIDP).

Results

In the sample, 86.9% had no minimum ODP component. Negative multivariate binomial regression showed a statistically significant relationship (p < 0.005) between ODB and all variables analyzed (skin color, family income, education, OIDP results and age range). The adjusted multivariate binary logistic regression showed that the individuals most likely to have at least one component of ODB were nonwhite (25.5%), had a family income of up to R$ 1500.00/month (19.6%), had only completed primary education (19.1%), and reported that their oral health had an impact on their daily activities (57.6%). Older adults individuals were two times more likely than adolescents to have an ODB component.

Conclusions

ODB is associated with factors related to social inequality. Adults and older adults individuals had the highest cumulative number of ODB components.

A community survey on maternal perception about the initiation of dental home for infants in Lagos, Nigeria

INTRODUCTION

because efforts directed toward oral health promotion and disease prevention are fundamentally superior to dental rehabilitation after disease development, early preventive dental visits are widely encouraged by dental professional and academic stakeholders. Aim: this study aimed to determine the perceptions and practices of mothers with regards to the establishment of dental home at four local government areas (LGAs) in Lagos, Nigeria.

METHODS

was a community-based descriptive household survey conducted amongst mothers in Alimosho, Ikorodu, Surulere and Epe LGAs of Lagos State. Socio-demographic data, information about the importance of primary teeth, knowledge about dental home as well as their child´s age at first dental visit and reasons for attending was obtained with a validated, structured interviewer administered questionnaire. Descriptive statistics, Chi-square and multivariable regression analysis were conducted, and the level of significance was set at P<0.05.

RESULTS

the highest proportion of the mothers were aged between 26-30 years (27.4%; mean age: 34.58±7.8 years) and had a tertiary level of education (n=206, 59.9%); most respondents (n=80, 51.4%) did not know the age a child should be taken to the dental clinic for the first time and had not taken their child for any dental visit (n=229, 65.4%). Out of those who had previously taken their child for dental visits, the greater proportion (n=115, 95.0%) took the child when he/she was older than one year of age. Overall, only 126 (36.0%) respondents had a good perception about oral health and the need for a dental home while 224 (64.0%) respondents had poor knowledge. Logistic regression analysis of predictor variables that showed mothers with a tertiary level of education (OR=0.108; CI=0.0023-0.495) and those with 2-3 children (OR=0.482; CI=0.253-0.920) had significant lower odds of poor perception about the importance of a dental home.

CONCLUSION

maternal knowledge and practices with regards to dental home were poor and inadequate. It is necessary to create more awareness among parents/caregivers, especially through antenatal and immunization clinics to establish the concept of dental home.

Health literacy on oral health practice and condition in an adult and elderly population

The objective of this study was to investigate the impact of health literacy (HL) on health practices and oral health outcomes in an adult and elderly population in Brazil. A cross-sectional study nested in a cohort study was followed up over a period of four years (2011 and 2015) and assessed individuals between 23 and 69 years old from Piracicaba, São Paulo, Brazil. Data were collected by means of oral examinations (coronal caries, periodontal disease and visible biofilm) and interviews (socioeconomic, demographic, oral health-related quality of life, health practices and HL). The 14-item Health Literacy Scale (HLS) was used for HL data, which was the main explanatory variable. The result of the sum of the HLS-14 questionnaire for each participant was dichotomized into the median (46 points): 'high' and 'low' HL. Binary/multinomial logistic regressions were performed on health practice and oral health outcomes, controlled by age and sex (Model 1) and age, sex and socioeconomic status (Model 2; p < 0.05). The final sample consisted of 137 subjects and 43.8% (n = 60) presented low HL (LHL). LHL was associated with health practices, such as use of public dental services in Model 1 (odds ratio [OR] = 0.34, 95% CI: 0.14-0.87) and use of dental services for emergency in Model 1 (OR = 2.69, 95% CI: 1.29-5.51) and Model 2 (OR = 2.93, 95% CI: 1.17-7.30). Based on age and sex, LHL was associated with use of public dental service and use of emergency dental visits. Based on age, sex and socioeconomic status, LHL was associated with use of emergency dental visits.

[Frugal dentistry-saving resources with a focus on core functions and patient needs]

Frugal dentistry is derived from the term "frugal" (meaning simple, economical, usable, suitable). It focuses on dental interventions, which on one hand leads to a cost reduction compared to treatment alternatives and on the other hand focuses on dental core functionalities taking into account the patient's needs. In 2020, the World Health Organization (WHO) highlighted the urgency to prioritize cost-effective and affordable interventions.Against this background, a classification and review of frugal dentistry is carried out in this article. To what extent its objectives can be substantiated is investigated. Based on literature sources and an exemplary clinical presentation, options for frugal dentistry are shown. In addition, examples of potential frugal interventions and innovations are named and explained for a number of subject fields in dentistry. There are serious deficits in the systematic development and implementation of frugal dentistry. Numerous efforts in research, teaching, and patient care are therefore still required.

Determinants of dental caries in children in the Middle East and North Africa region: a systematic review based on literature published from 2000 to 2019

Background

Dental caries risk factors have been expanded to not only emphasize biology, dietary and oral habits but also broader social determinants such as socioeconomic factors and the utilization of health services. The aim was to review sociobehavioural/cultural and socioeconomic determinants of dental caries in children residing in the Middle East and North Africa (MENA) region.

Methods

A search was conducted in the PubMed/Medline database and Google Scholar to identify studies published from 2000 to 2019 covering children using key search terms. In the initial stages, titles, abstracts and, if needed, full articles were screened for eligibility. In the final stage, all included articles were reassessed and read, and relevant data were extracted.

Results

Out of 600 initial articles, a total of 77 were included in this review, of which 74 were cross-sectional, 2 were longitudinal and one was a case–control study. The studies included a total of 94,491 participants in 14 countries across the MENA region. A majority used the World Health Organization scoring system to assess dental caries. The caries prevalence ranged between 17.2% and 88.8%, early childhood caries between 3% and 57% and decayed missing filled teeth (dmft) varied between 0.6 and 8.5 across the various age groups. Increased age, low maternal education, low overall socioeconomic status, decreased frequency of tooth brushing, low parental involvement, poor oral habits, infant feeding practices and sugar consumption were among the most prevalent determinants for increased risk of caries in the reviewed studies.

Conclusions

Dental caries was found to be high among children in many of the studies published from MENA. The key determinants of dental caries were found to include factors related to child characteristics, family background, oral hygiene and infant feeding and eating habits. The high dental caries prevalence emphasises the need to address the prevailing modifiable sociobehavioural and socioeconomic determinants by translating them into effective oral health prevention policies and programmes.

Impact of adopting different socioeconomic indicators in older adults' oral health research

This study aimed to evaluate the influence of choosing different socioeconomic status indicators in research regarding older adults' oral health. This is a cross-sectional study that analyzed baseline data from the Brazilian Longitudinal Study on Aging (ELSI-Brazil). The outcomes were edentulism (n = 9,073) and self-reported oral health (n = 9,365). The following socioeconomic indicators were assessed: individual income, per capita household income, and wealth index. Poisson regression analysis with robust variance was performed to estimate prevalence ratios (PR), with their respective 95% confidence intervals (CI), after adjusting for socioeconomic and oral health behavior variables. Absolute inequality measures were also estimated. The individual income indicator was not statistically associated with the results after adjustments. When using per capita household income indicator, individuals in the richest quintile showed a 12% lower prevalence of poor self-reported oral health [PR: 0.88 (CI: 0.78-0.98)], relative to the poorest, and there was no association with edentulism. When the wealth index was chosen, there was a 22% lower prevalence of edentulism [PR: 0.78 (CI: 0.64-0.94)] and 15% lower prevalence of self-reported poor oral health [PR: 0.85 (CI: 0.78-0.93)] in individuals of the richest quintile, both relative to the poorest quintile. Regarding absolute inequality measures, for edentulism, the wealth index showed the highest absolute inequality. When considering self-reported oral health, per capita household income showed the greatest absolute inequality. Despite scientific challenges and the difficulty of socioeconomic indicator metrics, further investments in its development are critical to measure, promote, and improve population oral health.

Neighbourhood characteristics and children's oral health: a multilevel population-based cohort study

Background

To understand determinants of oral health inequalities, multilevel modelling is a useful manner to study contextual factors in relation to individual oral health. Several studies outside Europe have been performed so far, however, contextual variables used are diverse and results conflicting. Therefore, this study investigated whether neighbourhood level differences in oral health exist, and whether any of the neighbourhood characteristics used were associated with oral health.

Methods

This study is embedded in The Generation R Study, a prospective cohort study conducted in The Netherlands. In total, 5 960 6-year-old children, representing 158 neighbourhoods in the area of Rotterdam, were included. Data on individual and neighbourhood characteristics were derived from questionnaires, and via open data resources. Caries was assessed via intraoral photographs, and defined as decayed, missing and filled teeth (dmft).

Results

Differences between neighbourhoods explained 13.3% of the risk of getting severe caries, and 2% of the chance of visiting the dentist yearly. After adjustments for neighbourhood and individual characteristics, neighbourhood deprivation was significantly associated with severe dental caries (OR: 1.48, 95% CI: 1.02–2.15), and suggestive of a low odds of visiting the dentist yearly (OR: 0.81, 95% CI: 0.56–1.18).

Conclusions

Childhood caries and use of dental services differs between neighbourhoods and living in a deprived neighbourhood is associated with increased dental caries and decreased yearly use of dental services. This highlights the importance of neighbourhoods for understanding differences in children’s oral health, and for targeted policies and interventions to improve the oral health of children living in deprived neighbourhoods.

Analysis of gum bleeding among children aged 12-15 years in Jiangxi Province and related influencing factors

OBJECTIVE

To study the prevalence of gum bleeding in children aged 12-15 years in Jiangxi Province and related influencing factors for the development of effective prevention and treatment strategies.

METHODS

A multistage cluster stratified sampling method was used to select 8,160 children aged 12-15 years for this study. Enrolled children completed a set of survey questionnaires covering children's gender, age, parents' educational level, oral health knowledge scores, attitude scores, and brushing habits in addition of dental examination. All the data were analyzed using the chi-square test and logistic regression.

RESULTS

Among 8,160 children, the gum bleeding rate was 66.5 percent (95% CI: 65.8%-68.1%). The gum bleeding rate in urban children (68.0 percent) was higher than that in rural areas (65.0 percent) (P < 0.01); the gum bleeding rate in boys (67.6 percent) was higher than that in girls (65.4 percent) (P < 0.05). The results of binary logistic regression analysis showed that age, urban and rural areas, mother education, knowledge score, attitude score, and brushing frequency were all important factors affecting gum bleeding.

CONCLUSION

This study showed that incidence of gum bleeding in Jiangxi children is high which is affected by their age, mother's education, and several other factors. These new findings form the baseline information essential for the development of more effective approaches to prevent and control children gum bleeding in Jiangxi and other regions in the future.

Evaluation of a community-based early childhood caries (ECC) intervention in Cambodia

OBJECTIVE

To critically evaluate an early childhood caries (ECC) intervention performed by non-dental primary healthcare providers.

METHODS

This mixed-methods investigation includes data from three sources: (a) a pilot non-randomized controlled trial to examine clinical outcomes at four health centres; (b) stakeholder focus group interviews; and (c) a survey of parents whose children were exposed to the intervention. The pilot study involved four Community Health Centres in rural Cambodia whereby mother-child (6-24 months of age)dyads received oral health education (OHE), toothbrushes, fluoride toothpaste and fluoride varnish on up to six occasions as part of the routine vaccination schedule. Outcomes were as follows: presence of ECC; impacts on oral health-related quality of life (OHRQoL); stakeholder perceptions of intervention delivery; and parental perceptions of fluoride varnish.

RESULTS

Participants in the intervention group had six times lower odds of developing ECC than those in the comparison group after controlling for socio-economic status (OR 0.13). Those in the intervention group also had a large reduction OHRQoL scale scores. Key knowledge and practice gaps were identified among stakeholders. Surveyed parents had favourable views of the fluoride varnish placement by medical professionals, and four out of five stated that they would recommend fluoride varnish for other children. Primary healthcare providers, commune council representatives and community health promoters supported oral health interventions being provided in CHCs.

CONCLUSIONS

OHE and fluoride varnish interventions provided by non-dental primary health workers were feasible and acceptable for stakeholders in a Cambodian setting. The intervention group had lower ECC experience and better OHRQoL at 2 years of age.

Geographical and socioeconomic inequalities in dental attendance among children in Peru: Findings from the Demographic and Family Health Survey 2017

OBJECTIVE

The aim of the study was to explore the presence of inequalities in the use of dental services among <12-year-old children residing in Peru, according to their wealth quintile and natural region of residence.

METHODS

This was a cross-sectional secondary data analysis of the 2017 Demographic and Family Health Survey of Peru (n = 39 881 children). Generalized Poisson regression models, adjusted for gender, age, maternal ethnicity, place of residence and health coverage, were used to study the association between wealth quintile and use of dental services followed by stratified models by the natural region (Metropolitan Lima, coast, Andes mountains and jungle) and predicted probability graphs to study the effect of the natural region on inequalities in the use of dental services.

RESULTS

Inequalities in the use of dental services among children were observed according to the wealth quintile and natural region. A social gradient was present in the Andes mountains, coast and jungle regions. The greatest inequalities were observed in the coast (richest vs poorest quintile PR = 1.81 95% CI = 1.56-2.11) and jungle regions (richest vs poorest quintile PR = 1.81 95% CI = 1.53-2.14). The jungle presented the lowest proportion of children using dental services, while Metropolitan Lima had the highest proportion. No significant differences were observed between wealth quintiles among children from Metropolitan Lima.

CONCLUSIONS

Differences in socioeconomic inequalities in the use of dental services among natural regions were observed. The distribution of dental centres and personnel, and the geographical and demographic characteristics of each region, may play an important role in the presence of the inequalities observed.

Number of Remaining Teeth and Its Association with Educational Level in Chilean Adults: Data from the National Health Survey 2016-2017

Introduction

Several population studies have addressed oral health inequalities. Edentulism, functional dentition, and number of remaining teeth have been associated with different socioeconomic level measurements. The aim of this study was to evaluate the association between educational level and tooth loss in the Chilean population aged 15 years and above, based on the 2016-2017 National Health Survey (ENS 2016-2017). Material and Methods. The sample for this cross-sectional study comprised 5473 subjects. The main independent variable was educational level (LEL: low, MEL: medium, and HEL: high). To measure tooth loss, we considered the variables number of remaining teeth, edentulism, and functional dentition. We used logistic regressions to assess the condition of dentition according to the subject's EL. As to the number of teeth variable, linear regressions were conducted. The analyses were carried out considering the complex sampling design in SPSS 24.0.

Results

When comparing LEL subjects with HEL subjects, the adjusted difference in number of remaining teeth was 3.11 for the maxilla and 1.72 for the mandible. An individual with LEL had a 7.51 [3.50-16.10] and 6.06 [2.68-13.68] times higher risk of upper edentulism and lower edentulism than a HEL individual, respectively. Regarding functional dentition, the adjusted OR in HEL subjects was 13.33 [8.02-22.15] and in MEL subjects was 2.81 [2.03-3.87], compared to LEL results.

Conclusions

LEL was associated with a significant tooth loss in the Chilean population. Subjects with LEL obtained a lower mean of number of remaining teeth and higher prevalence of edentulism and nonfunctional dentition.

Clinical and sociodemographic factors associated with oral health knowledge, attitude, and practices of adolescents in Nigeria

Objectives:

The institution of appropriate oral health promotion programs targeted at adolescents in schools in developing countries requires baseline information on their oral health knowledge, attitude, and practices as well as associated factors influencing it, which are unknown. This study assessed clinical and sociodemographic factors associated with oral health knowledge, attitude, and practices of adolescents in Ibadan, Nigeria.

Methods:

Two-thousand and ninety-seven students aged 12–18 years were recruited from 30 randomly selected secondary schools in a cross-sectional study conducted in Ibadan, Nigeria. Data were obtained through a questionnaire on oral health knowledge, attitude, and practices, and sociodemographic characteristics. Oral examination was conducted to assess the clinical oral condition of the adolescents. Data were analyzed with SPSS. The higher the percentage scores, the better the oral health knowledge, attitude, and practices, and overall awareness of oral health.

Results:

The oral health knowledge score ranged from 0% to 60%; mean oral health knowledge score was 15.1% (±6.6%). The oral health attitude score ranged from 0% to 91.3%; mean oral health attitude score was 44.5% (±14.3%). The oral health practices score ranged from 0% to 88.9%, and mean oral health practices score was 42.5% (±13.8%). The mean oral health knowledge, attitude, and practices score was 43.8% (±11.4%). A total of 1537 (73.3%) participants had unhealthy periodontium and 98 (4.7%) had dental caries. Students who were 12–15 years (odds ratio = 1.7, 95% confidence interval = 1.4–2.0, p < 0.001), females (odds ratio = 1.2, 95% confidence interval = 1.0–1.5, p = 0.024), offspring of skilled workers (odds ratio = 1.5, 95% confidence interval = 1.1–2.0, p = 0.010), previously educated about oral health (odds ratio = 1.3, 95% confidence interval = 1.0–1.7, p = 0.023), consulted the dentist (odds ratio = 1.9, 95% confidence interval = 1.2–3.1, p = 0.009), or had unhealthy periodontal condition (odds ratio = 1.2, 95% confidence interval = 1.0–1.5, p = 0.042) were more likely to have higher oral health knowledge, attitude, and practices scores or awareness than others.

Conclusion:

Better knowledge, attitude, and practices score was associated with younger age group, higher occupational class, previous oral health education, dental consultation, and having unhealthy periodontal condition.

Health promotion competencies for promoting child-oral health: Victorian multidisciplinary workforce perspectives

ISSUE ADDRESSED

Population oral health (OH) improvements depend on successful, coordinated execution of oral health promotion (OHP) programs by both oral and general health professionals with key competencies (skills, abilities, knowledge and values). This study explored multidisciplinary professionals' perspectives of the competencies required for the successful implementation of a community-based OHP program called Smiles 4 Miles (S4M) in early childhood settings in Victoria, Australia.

METHODS

Convenience sampling was used to recruit multidisciplinary professionals working in the S4M early childhood health promotion program in Victoria. Semi-structured focus groups were conducted with program managers/coordinators (n = 26) from 21 S4M sites and the state-wide program coordination team (n = 5). Focus groups explored OHP competency needs, capacity to promote child OH and strategies for enhancing OHP competencies. The competencies identified through focus groups were then compared to the International Union for Health Promotion and Education (IUHPE) competencies framework.

RESULTS

Strategies to enhance individual and organisational OHP competencies included intersectoral collaborations; working in multidisciplinary teams; support networks and partnerships; sharing skills and expertise between health professionals. The OHP competencies identified by the participants were consistent with key IUHPE domains including ethical values and health promotion knowledge base underpinning, enabling change, advocacy for health, mediating through partnerships, communication, leadership, assessment, planning, implementation, evaluation and research.

CONCLUSION

A multidisciplinary workforce based in community settings can play key and complementary roles in OHP and widen avenues for oral disease prevention. SO WHAT?: Integrated collaborative workforce models involving multidisciplinary professionals beyond the OH sector can more effectively support efforts to address the burden of oral disease.

The knowledge and practice of pediatricians in children's oral health: a scoping review

BACKGROUND

Dental caries is a significant public health problem and one of the most common chronic conditions affecting children. The potential for the non-dental workforce to improve children's oral health is well documented. For well over a decade, there have been calls for pediatricians to address children's oral health, but the incorporation of oral health screening, referral, and oral healthcare in pediatric practice remains underdeveloped. Developing action to strengthen the role of pediatricians' in children's oral health requires an understanding of their current knowledge and practice. In this scoping review, we aimed to comprehensively map what is known about the knowledge and practice of pediatricians regarding children's oral health.

METHODS

Arksey & O'Malley's five-stage review process was used to comprehensively map studies undertaken on pediatrician's knowledge and practice regarding children's oral health. Key search terms were developed and a total of 42 eligible articles are included in the review.

RESULTS

The studies were conducted in 19 countries. The majority (41/42) were quantitative, with over 90% using self-reported surveys. Only four studies used previously validated survey tools, with most adapting questions from previous studies. Observational designs were used in two studies and one used qualitative methods. Sample size ranged from 15 to 862. Oral health knowledge amongst pediatricians was reported to be mostly poor, with many gaps in key areas including age for first dental visit, dental caries and oral health risk assessments. Studies on the translation of oral health knowledge to practice were limited, with wide variation in rates of assessment. Few studies assessed actual practice.

CONCLUSIONS

This scoping review highlights growing international interest in the role of pediatricians in children's oral health. Findings demonstrate that pediatricians have limited knowledge and understanding in critical areas, including; initial clinical signs of dental caries, recommended age for first dental visit, etiology of dental caries and recommended use of fluorides. Barriers for pediatricians include inadequate education and training, time constraints in practice and lack of referral pathways. Development of a validated tool to assess knowledge and practice is needed. This review provides a starting point to guide future research and areas for systematic reviews.

Patient-based outcomes and quality of life

Patient-based outcomes complement clinical data with patients' self-evaluation of their physical, psychological, and social well-being, and as such facilitate clinical decision-making, assessing the quality of care provided, and evaluating practices and policies. Some validated generic oral health-related quality of life measures used in recent research indicated a high performance. There is a proportional relationship between the quality of life and periodontitis, ie, the higher the level of periodontitis, the poorer the oral health-related quality of life. This relationship is heightened by the presence of symptoms such as bleeding, halitosis, and mobility. On the other hand, periodontal treatment has demonstrated the capability to improve quality of life substantially. Future research should focus on questionnaires that are able to explain the interlinked pathways between periodontal conditions, approaches to treatment approaches, and patients' well-being. The acquisition of new knowledge in the field is essential for the whole community, as we treat people not millimeters.

Oral health impacts among Australian adults in the National Study of Adult Oral Health (NSAOH) 2017-18

BACKGROUND

This paper examines oral health impacts of toothache experience, self-rated oral health (SROH), being uncomfortable with dental appearance, and avoiding foods in the Australian adult population.

METHODS

The explanatory variables include age, sex, region, income, area-based SES, dental insurance and visiting pattern. The data were collected in the interview in NSAOH 2017-18.

RESULTS

There were lower percentages with: toothache in the highest (14.8%) than middle (21.2%) and lower income tertiles (25.2%); fair/poor SROH in the highest (15.8%) than middle (24.1%) and lower tertiles (34.8%); uncomfortable with appearance in the highest (29.1%) than middle (35.3%) and lower tertiles (42.2%); and food avoidance in the higher (15.3%) than middle (22.9%) and lower tertiles (34.4%). There were higher percentages with: toothache in the unfavourable (32.2%) than intermediate (23.1%) and favourable (11.7%) visiting groups; fair/poor SROH in the unfavourable (44.0%) than intermediate (27.4%) or favourable (10.2%) groups; being uncomfortable about appearance in the unfavourable (47.6%) than intermediate (39.5%) or favourable (25.8%) groups; and avoiding foods in the unfavourable (34.8%) than intermediate (26.0%) or favourable (14.5%) groups.

CONCLUSIONS

Socioeconomic status and dental visiting were associated with oral health impacts. Oral health impacts were worse for those with lower income and unfavourable visiting patterns.

Income at birth and tooth loss due to dental caries in adulthood: The 1982 Pelotas birth cohort

OBJECTIVE

To estimate the effect of income at birth on adulthood tooth loss due to dental caries in 539 adults from the 1982 Pelotas birth cohort.

METHODS

Family income was collected at birth. Tooth loss was clinically assessed when individuals were aged 31. Dental visit and oral hygiene at age 25 were considered mediators. Confounders included maternal skin color, and individual's skin color, sex, and income in adulthood. Marginal structural modeling was used to estimate the controlled direct effect of income at birth on tooth loss due to dental caries that was neither mediated by the use of dental service nor oral hygiene.

RESULTS

Forty-three percent of the individuals of low income at birth lost one/two teeth, and 23% lost three or more; among those non-poor, the prevalence was 30% and 14%, respectively. Poor individuals at birth had a 70% higher risk for missing teeth in adulthood than those non-poor. The risk of losing one/two (risk ratio 1.68) and three or more teeth (risk ratio 3.84) was also higher among those of low income at birth.

CONCLUSIONS

Economic disadvantage at birth had an effect on tooth loss due to dental caries at age 31 not mediated by individual risk factors.

The school social environment and oral health-related quality of life in children: a multilevel analysis

This study aimed to explore the association between schoolchildren's oral health-related quality of life (OHRQoL) and the school-related social environment (contextual factors). A cross-sectional study was performed with 1,211 children, aged 8-12 yr, from 20 private and public schools. Sociodemographic information was collected from a questionnaire given to parents, and children were interviewed using the Child Perceptions Questionnaire (CPQ) and examined for oral health conditions. Contextual variables were obtained from school coordinators regarding the social environment. Data analysis was performed through multilevel Poisson regression. A high negative impact on OHRQoL was found for participants who were girls, older, had very severe malocclusion, had dental trauma and caries, and had mothers with less schooling. A negative impact on OHRQoL was also found for children who attended schools in which police security was required (rate ratios [RR] = 1.11; 95% CI: 1.01-1.22) and in which violence among students occurred in the last year (RR = 1.17; 95% CI: 1.02-1.35). The need for police security was associated with a negative impact on the emotional well-being domain, and violence among students was associated with negative impact on the oral symptoms, functional limitations, and social well-being domains. Children in healthier environments have better OHRQoL.

Reducing social inequalities in the oral health of an adult population

The objective of this study was to evaluate the association between social inequality indicators and oral health conditions in an adult population. This prospective cohort study assessed a probabilistic sampling of adults (aged 20-64 years) living in Piracicaba, São Paulo, Brazil. Oral examinations were performed in 2011 and 2015, conducted at home, and used the decay-missing-filled (DMFT) index of permanent teeth, the Community Periodontal Index (CPI), and the visible biofilm criterion. A questionnaire was administered to determine demographic and socioeconomic aspects and dental services used, and collect oral health-related quality of life (OHRQoL) data. Social inequality indicators were evaluated according to social class (high, middle or low) and type of dental service used (public, health insurance or private), and compared with oral health conditions (visible biofilm, DMFT and incidence of tooth loss, periodontal pockets and bleeding, and OHRQoL), evaluated between 2011 and 2015. Analysis using chi-squared or Fisher tests (p < 0.05) and Cochran's Q test was conducted separately for each category analyzed between 2011 and 2015 (p < 0.05). A total of 143 adults who participated in an earlier study were examined after four years of follow-up. Although the occurrence of oral disease did not decrease over the study period (4 years), there was a reduction in inequality among lower social classes in regard to presence of tooth decay and oral health impact on self-perceived quality of life between 2011 and 2015 (p < 0.05). These results suggest that the Brazilian National Oral Health Policy has achieved its principles, especially that of greater equity.

Does the national dental scaling policy reduce inequalities in dental scaling usage? A population-based quasi-experimental study

Background

In 2013, the national dental scaling insurance policy was introduced in South Korea. The purpose of this study is to determine the impact of the policy on inequalities in dental scaling usage.

Methods

Data of a nationally representative sample of 1,517,097 people over the age of 20 were obtained from the 2010–2016 Community Health Survey. Respondents who reported that they had not received dental scaling in the past year were defined as dental scaling non-users. The excess prevalence and relative prevalence ratio of dental scaling non-users were calculated for the pre-policy (2010–2012) and post-policy periods (2014–2016) using monthly household income levels. Additionally, trends of dental scaling inequalities were shown as concentration indexes.

Results

The prevalence of dental scaling non-users declined from 58.0 to 48.7% in the highest income group and from 86.3 to 78.8% in the lowest income group. However, the adjusted excess prevalence for the lowest income group compared with the highest had increased from 11.9 (95% CI: 11.9–11.9) to 15.5 (95% CI: 15.5–15.5)%, and the adjusted prevalence ratio increased from 1.19 (95% CI: 1.19–1.20) to 1.29 (95% CI: 1.29–1.30). Absolute and relative concentration indexes of dental scaling non-users increased after policy implementation.

Conclusions

The national dental scaling insurance policy has increased socioeconomic inequalities in dental scaling usage. Because dental care access generally requires high individual agency, expanded dental coverage may have had limited effects in attenuating inequalities and inadvertently widened the gap. To reduce dental care inequalities, universal access with universal dental coverage should be considered.

Socioeconomic inequalities in oral health-related quality of life in adolescents: a cohort study

PURPOSE

Socioeconomic inequalities are recognized as a major problem with people in low socioeconomic groups having worse subjective oral health outcomes, including oral health-related quality of life (OHRQoL). However, only a few longitudinal studies assessed the impact of contextual and individual socioeconomic determinants in adolescents' OHRQoL. We estimate the impact of socioeconomic inequalities on adolescents' OHRQoL over a 2-year period.

METHODS

This study followed up a random sample of 1134 12-year-old schoolchildren for 2 years in Brazil. OHRQoL was assessed by the Brazilian version of the Child Perceptions Questionnaire for 11- to 14-year-old Children (CPQ11-14) at baseline and follow-up. Participants were clinically examined for dental caries, gingival bleeding, and malocclusion. The schoolchildren's parents answered a questionnaire regarding socioeconomic status, social capital, and adolescents' use of dental service. Socioeconomic contextual variables were collected from official city publications. Multilevel linear regression models fitted the associations between socioeconomic factors and overall CPQ11-14 scores over time.

RESULTS

A total of 747, 14-year-old adolescents were reassessed for OHRQoL (follow-up rate of 66%). Adolescents with lower mean income school's neighborhood (P < 0.05), household income (P < 0.05), and maternal schooling (P < 0.05) had higher overall CPQ11-14 scores. Female sex, attending a dentist by toothache, dental caries, and malocclusion were also associated with higher overall CPQ11-14 scores.

CONCLUSIONS

Adolescents from low socioeconomic background reported worse OHRQoL at 2-year follow-up compared to those from high socioeconomic background. Actions toward health inequalities need to address socioeconomic factors in adolescence.

[Primary dental healthcare in Brazil: the work process of oral health teams]

Ensuring access to dental care services requires the development of healthsurveillance practices to ensure comprehensive health care. The objective of this study was toinvestigate the association between social and economic indicators of Brazilian municipalities, work process characteristics, and performance of a list of curative dental procedures by oral health teams. It involved an exploratory, cross-sectional study withmulticenter data collection from 11,374 oral health teams assessed by the National Program for Improvement of Access to and Quality of Primary Healthcare. Multilevel Poisson regression was used to obtain the prevalence of curative dental procedures, which was 69.51%. The social/economic and work variables that remained associated with the outcome included municipalities in which the proportion of primary care-sensitive admissions was below 28% and that of tooth extractions below 8%; and oral health teams classified as type II (including oral health assistant and technician) that had different materials available and better work processes. This multilevel analysis, which took into consideration the performance of curative dental care in Brazil, reveals a worrying oral healthcare scenario.

A public health perspective on personalized periodontics

In this paper, we consider personalized periodontics from a public health perspective. Periodontitis is an under-acknowledged and important public health problem, and there has long been interest in identifying and treating those who are at high risk of developing this disease. Although susceptibility/risk-assessment tools in periodontology are currently in their early stages of development, personalized periodontics is increasingly becoming a realistic approach. At the population level, however, personalized periodontics is not an effective way of improving periodontal health because it would target only those who seek help or are able to access care. The occurrence of periodontitis in populations is socially patterned, with those of lower socio-economic position having poorer periodontal health and being far less likely to seek care. There is the potential for social inequalities actually to worsen as a result of personalized periodontics. In most health systems, personalized periodontics is likely to be accessible only to the social strata for whom it is affordable, and those with the greatest need for such an intervention will remain the least likely to be able to get it. Thus, personalized periodontics is likely to be a niche service for a small proportion of the adult population. This is at odds with the public health approach.

Impact of Dental Diseases on Quality-Adjusted Life Expectancy in US Adults

Comparing the burden of dental conditions to other health outcomes provides useful insight for public policy. We aimed to estimate quality-adjusted life expectancy (QALE) loss due to dental conditions in the US adult population. Social inequalities in QALE loss by dental conditions were also examined. Data from 3 cross-sectional waves of the National Health and Nutrition Examination Survey (NHANES waves 2001 to 2002, 2003 to 2004, and 2011 to 2012) were pooled and analyzed. The average age of study participants ( n = 9,445) was 48.4 y. Disutility scores were derived from self-rated health and the numbers of physically unhealthy days, mentally unhealthy days, and days with activity limitation, employing a previously published algorithm. The associations between the disutility scores and the numbers of decayed teeth, missing teeth, and periodontitis were examined by multiple linear regression stratified by age groups (20–39, 40–59, and ≥60 y), adjusted for other covariates (age, sex, wave fixed effect, educational attainment, smoking, and diabetes). The QALE loss due to dental conditions at the age of 20 was estimated using life tables. Decayed and missing teeth, but not periodontitis, were associated with a larger disutility score. The coefficient for decayed teeth was larger among the older population, whereas that of missing teeth was smaller among them. The estimated QALE loss was 0.43 y (95% confidence interval [CI], 0.28–0.59), which reached 5.3% of QALE loss (8.15 y; 95% CI, 8.03–8.27) due to overall morbidity. There were clear social gradients in QALE loss by dental conditions across the life course, and people with high school or less education had 0.32 y larger QALE loss in total compared with people with college or more education. This study suggests that improvements in people’s dental health may yield substantial gains in population health and well-being. The necessity of more comprehensive public health strategies is highlighted.

Early Life Professional and Layperson Support Reduce Poor Oral Hygiene Habits in Toddlers-A Prospective Birth Cohort Study

Oral health behaviours of children are formulated from a very young age. Formation of those behaviours among very young children is dependent on their mothers/caregivers who may themselves require support from the health profession or laypersons. The study aimed to investigate if early life visits for check-up and dental advice and perceived support improved oral health behaviours as practiced by mothers of toddlers aged 24–30 months old. Data from a population-base birth cohort study in South Australia was used. The study recruited and followed mothers of newborn children from birth to age 24–30 months. Parental questionnaires collected information about socioeconomic factors, dental visiting patterns, and oral health behaviours as practiced by the mothers for their child. Self-reported putting a child to bed with a bottle and brushing a child’s teeth were the outcome variables. The two main exposures of this study were (1) early visiting for a dental advice, and (2) layperson support that a mother received in the first two years of having the child. Data were analysed progressively from bivariate to multivariable regression models. A total of 1183 mother/child dyads had complete data. The retained sample was representative of the population. Approximately 36% of mothers put their child to bed with a bottle and 26% of mothers did not brush their child’s teeth the night before. Around 29% of children had a visit for dental check-up and 80% of mothers reported having lay support. There were gradients in the outcome variables by socioeconomic factors and the main exposures. Multivariable regression models reported that having no dental visit for advice and having no lay support were associated with 1.30 and 1.21 imes higher rates of putting a child to bed with a bottle, respectively. Having no dental visit for advice was associated with a 1.37-times higher rate of not brushing a child’s teeth, controlling for other factors. This population-based birth cohort study confirmed importance of early life dental visit for check-up and support for mothers of young children in establishing oral health behaviours of young children.
