Mind the gap! A comparison of oral health knowledge between dental, healthcare professionals and the public

Isotopological remeshing and statistical shape analysis: Enhancing premolar tooth wear classification and simulation with machine learning

OBJECTIVE

The aim of this study was to evaluate the accuracy of a combined approach based on an isotopological remeshing and statistical shape analysis (SSA) to capture key anatomical features of altered and intact premolars. Additionally, the study compares the capabilities of four Machine Learning (ML) algorithms in identifying or simulating tooth alterations.

METHODS

113 premolar surfaces from a multicenter database were analyzed. These surfaces were processed using an isotopological remeshing method, followed by a SSA. Mean Euclidean distances between the initial and remeshed STL files were calculated to assess deviation in anatomical landmark positioning. Seven anatomical features were extracted from each tooth, and their correlations with shape modes and morphological characteristics were explored. Four ML algorithms, validated through three-fold cross-validation, were assessed for their ability to classify tooth types and alterations. Additionally, twenty intact teeth were altered and then reconstructed to verify the method's accuracy.

RESULTS

The first five modes encapsulated 76.1% of the total shape variability, with a mean landmark positioning deviation of 10.4 µm (±6.4). Significant correlations were found between shape modes and specific morphological features. The optimal ML algorithms demonstrated high accuracy (>83%) and precision (>86%). Simulations on intact teeth showed discrepancies in anatomical features below 3%.

CONCLUSION

The combination of an isotopological remeshing with SSA showed good reliability in capturing key anatomical features of the tooth.

CLINICAL SIGNIFICANCE

The encouraging performance of ML algorithms suggests a promising direction for supporting practitioners in diagnosing and planning treatments for patients with altered teeth, ultimately improving preventive care.

Comparative Perceptions of Fluoride Toxicity in Oral Hygiene Products: Insights from the General Population and Healthcare Professionals

BACKGROUND

The safety of oral hygiene products is a growing concern, particularly regarding the toxicity of specific ingredients used in their formulations. The purpose of this study was to evaluate the knowledge and attitudes of dentists, physicians, pharmacists, and the general public regarding ingredients in oral hygiene products, especially fluoride. Additionally, this study aimed to identify which ingredients may exhibit potential toxicity based on historical records of any adverse effects being induced by a material/component.

METHODS

A self-administered questionnaire was used in an online cross-sectional observational study to collect data on sociodemographic characteristics, knowledge of fluoride in dental medicine, fluoride usage practices in oral hygiene products, opinions on ingredient toxicity in oral hygiene products, and personal experiences of adverse reactions to products and their components. The collected data underwent descriptive and regression analyses to reveal patterns and relationships within the dataset.

RESULTS

The study found a moderate overall knowledge level regarding fluoride usage in dentistry among participants (Md = 5.00, IQR 2.50-7.00). Healthcare professionals exhibited significantly higher knowledge scores compared to the general population (p ≤ 0.001), with dental professionals displaying the highest scores. Regarding concerns about the usage of fluoride, the majority of respondents (77.0%) did not express any concerns. Minor concerns included the risk of ingestion (6.0%) and dental fluorosis (4.6%). Among the other ingredients in oral hygiene products, respondents named alcohol as the most toxic ingredient (70.3%), followed by artificial colors (53.1%), artificial sweeteners (50.4%), and parabens (50.1%). It is noteworthy that the majority of participants (61.6%) stated that they had never experienced any side effects associated with the use of oral hygiene products.

CONCLUSION

This study underscores disparities in fluoride knowledge between healthcare professionals and the general population in Croatia, with dental experts exhibiting a superior understanding. Despite lingering misconceptions about fluoride content and potential toxicity, the majority of participants acknowledge its oral health benefits and use fluoride products regularly.

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.

Improving oral health of children in four Balkan countries: A qualitative study among health professionals

Data from the WHO show that the oral health situation for children in the Balkan region of Europe is poor. This study aims to identify obstacles that prevent the implementation of an effective oral health program for children in the Balkan area. The study investigates the challenges that people encounter in increasing awareness, attending to dental care, and complying with examinations.

Methods

This qualitative study targeted experts in preventive dentistry and oral health promotion in four countries in the Balkan region. Purposive sampling was used to recruit the participants. Data were collected in 2021 using individual in-depth interviews with participants from Albania, Bosnia and Herzegovina, Croatia, and Serbia. The study applied the thematic analysis method.

Results

The experts reported four main challenges that hindered the implementation of a prevention program and regular patient attendance: (1) lack of knowledge, (2) the exclusion of oral health from overall health, (3) organization of services, and (4) skepticism of fluoride. The participants identified knowledge gaps among the general population, dental staff, and other health professionals regarding the prevention of oral diseases.

Conclusion

The findings of this study may be used to promote and improve oral health among children in the identified areas and to benefit people in the region and elsewhere. This study sheds light on the existing barriers in a region where people lack information.

Healthy Food, Healthy Teeth: A Formative Study to Assess Knowledge of Foods for Oral Health in Children and Adults

Eating patterns characterised by low intakes of processed carbohydrates and higher intakes of fat- and Vitamin D-rich foods are associated with protection against dental caries. The aim of this formative study was to evaluate the extent to which the knowledge of children and adults of foods for oral health reflects dietary guideline advice, and the evidence base for foods associated with increased and decreased caries burdens. Using a novel card-sorting task, the participants categorised foods according to their knowledge of each food for oral health. There were no differences between children and adults in the categorisation of fresh, minimally processed foods. Fish, chicken, and red meat were categorised as healthy by significantly fewer children than adults. High-sugar foods were correctly characterised as unhealthy by nearly all participants. More children categorised breakfast cereals as healthy than adults. There were no statistically significant differences between children and adults for the categorisation of brown or wholegrain breads categorised as healthy. The alignment of the participants’ beliefs with dietary guideline recommendations suggests education through health promotion initiatives is successful in achieving knowledge acquisition in children and adults. However, recommendations to increase the intake of refined carbohydrates inadvertently advocate foods associated with increased caries burdens.

Awareness and knowledge of dental erosion and its association with beverage consumption: a multidisciplinary survey

BACKGROUND

Erosive tooth wear has significant impacts on oral and general health. This study aimed to measure the awareness of dental erosion to establish the relationships among sociodemographic factors, awareness and knowledge of dental erosion, and beverage consumption behaviours, in a sample of university students in Australia.

METHODS

All undergraduate students enrolled in the targeted programs at an Australian University were invited. A total of 418 students consented to participate. Each was assessed with an online questionnaire.

RESULTS

The awareness rate of dental erosion was 92.1%. Soft drinks and fruit juice were most often perceived as acidic beverages by the respondents. The students of greater age, and studying pharmacy, paramedicine, physiotherapy or science, were less likely to be aware of dental erosion. Those students that were aware of dental erosion also had better knowledge of dental erosion, which was associated with a reduced quantity of daily acidic beverage consumption as well. The students that predominantly resided overseas had less knowledge of dental erosion. The students that were of greater age, that were studying clinical science, pharmacy, medical science, paramedicine, or science, and that correctly identified more types of acidic beverages, more often consumed acidic beverages in high-risk patterns.

CONCLUSIONS

Erosive tooth wear is a relevant matter in dentistry, nutrition and public health. Within a university setting, the effect of education on oral health literacy and beverage consumption behaviour is confirmed. Dental and health professionals should actively educate the individuals and communities about dental erosion and motivate them to change acidic beverage consumption behaviours.

COVID-19 Pandemic: Effect of Different Face Masks on Self-Perceived Dry Mouth and Halitosis

Due to the COVID-19 pandemic, the use of face masks has increased, resulting in potential health-related side-effects. Therefore, the study aimed to analyse the effect of wearing face masks on self-perceived dry mouth and halitosis. A questionnaire addressing the daily wearing time of different face masks (community masks, surgical/medical masks and KN95-/N95-/FFP2-masks) and self-perceived dry mouth and halitosis was given to adults attending or working at a university hospital. Statistical analysis was performed using Wilcoxon signed-rank test and multiple linear regression analysis (p < 0.05). 3750 participants (age: 50.4 ± 15.5 years; 60.0% female) were included. During the pandemic, face masks were used for 4.7 ± 3.8 h per day: community masks: 0.9 ± 2.0 h, medical/surgical masks: 1.9 ± 2.8 h and KN95-/N95-/FFP2-masks: 1.9 ± 2.5 h per day. The use of face masks significantly increased self-perceived dry mouth and halitosis (both p < 0.001). Self-perceived dry mouth and halitosis increased with increasing wearing time (community masks: dry mouth: p < 0.001, halitosis: p = 0.014; medical/surgical masks: both: p < 0.001; KN95-/N95-/FFP2-masks: dry mouth: p < 0.001, halitosis: p = 0.011). The perception of dry mouth and halitosis was increased in females compared to males (both: p < 0.001). Participants used to wearing face masks prior to the pandemic perceived dry mouth to a higher extent (p = 0.043). Self-perceived halitosis was lower in older than in younger participants (p < 0.001). Due to the increased perception of dry mouth and halitosis, people might abstain from wearing face masks. Further studies need to analyse measurable changes in dry mouth or halitosis.

Organizational Barriers to Oral Health Conversations Between Health Visitors and Parents of Children Aged 9-12 Months Old

Background: Dental caries is the most prevalent preventable childhood disease and a major public health priority. Local authorities in England have a statutory responsibility to improve child health, including oral health, through the “Healthy Child Programme.” The “Healthy Child Programme,” which includes the provision of oral health advice is delivered by health visitors to parents of young children. To date, research has mainly concentrated on individual interactions between health visitors and parents, with less attention given to the broader context in which these oral health conversations between health visitor and parents take place.

Objective: Our study explored the organizational factors that obstruct health visitors from engaging in meaningful conversations with parents about young children's oral health.

Methods: Qualitative interviews and focus groups were held with health visiting teams (n = 18) conducting home visits with parents of 9–12-month olds in a deprived, urban area in England.

Results: The study revealed the wide variation in what and how oral health advice is delivered to parents at home visits. Several barriers were identified and grouped into four key themes: (1) Priority of topics discussed in the home visits; (2) Finance cuts and limited resources; (3) Oral health knowledge and skills; and (4) Collaborative working with other professionals. It was evident that organizational factors in current public health policy and service provision play an important role in shaping oral health practices and opportunities for behavior change.

Conclusion: Organizational practices and procedures play an important role in creating interaction patterns between health visiting teams and parents of young children. They often limit effective engagement with and positive change in oral health. For future oral health interventions to be effective, awareness of these barriers is essential alongside them being founded on evidence-based advice and underpinned by appropriate theory.

Health professionals' knowledge, views and advice on diet and dental health: a survey of UK and Ireland dietitians and dentists

BACKGROUND

Oral health is affected by dietary practices and may impact quality of life. Collaboration between dietetics and dental professionals for oral health promotion and disease prevention is recommended. The present study aimed to determine the knowledge and practice of dentists and dietitians on diet and dental health.

METHODS

The study comprised a cross-sectional online questionnaire, which was disseminated electronically to dentists and dietitians in the UK and Ireland, via national networks. Questions assessed participants' knowledge of the cariogenicity of different foods, snacking behaviours, familiarity with UK dietary guidelines, dietary advice and their recommendations for cross-professional consistency.

RESULTS

In total, 418 responses were received (60% dentists, 40% dietitians). Inter-profession knowledge differences were observed for the cariogenicity of sports drinks (p < 0.001), chocolate/confectionary (p < 0.001), yoghurt (p < 0.001) and sugar-coated breakfast cereals plus milk (p < 0.0001). Dentists showed greater concern over the timings and frequency of food consumption than dietitians. A greater proportion of dentists felt nutrition and oral health counselling is a key component of regular patient care (58.4% versus 8.2%, p < 0.001). Only 18% of dietitians, compared to 56% of dentists, considered that they had received sufficient training about diet and dental health. Both professions indicated the need for multi-disciplinary training.

CONCLUSIONS

Dietitians and dentists differ with respect to their knowledge about the effects of snacks and snacking behaviours on dental health, as well as how they prioritise this in their clinical practice. Both professions show a willingness to work collaboratively to ensure accurate and consistent advice-giving and expertise-sharing.

Implementation of a behavioural change intervention to enhance oral health behaviours in elite athletes: a feasibility study

Background

Poor oral health of elite athletes is common and is associated with negative performance impacts. There is a need for oral health promotion strategies that are effective within the elite sport environment.

Aim

To develop, implement and evaluate a pragmatic oral health promotion intervention that integrated the capability, opportunity, motivation and behaviour model of behavioural change into the knowledge transfer system for effective implementation of preventive interventions.

Methods

Repeated measures study. Athletes and support team together viewed one 10 min presentation and three 90 s information films. Athletes alone received oral health screening, personalised advice and an oral health toolkit. Outcome measures included: (1) oral health knowledge, athlete-reported performance impacts (Oslo Sports Trauma Research Centre, OSTRC score), use of oral hygiene aids, gingival inflammation (bleeding) score, recorded at baseline, 4-6 weeks and 12-16 weeks and (2) athlete feedback.

Results

We recruited 62 athletes; 44 (71%) male and 58 (93.5%) white British, 55 (88.7%) athletes completed the study. Mean knowledge score improved from 5.69 (1.59) to 6.93 (1.32) p<0.001. Mean OSTRC score reduced from 8.73 (14.54) to 2.73 (11.31) p<0.001. Athlete use of prescription strength fluoride toothpaste increased from 8 (12.9%) to 45 (80.4%) p<0.001. Athlete-reported use of interdental cleaning aids at least 2-3 x week increased from 10 (16.2%) to 21 (34%) p=0.013. Bleeding score remained unchanged.

Conclusion

This behavioural change intervention was successfully implemented within different elite sport environments. It was associated with an increase in athlete oral health knowledge, enhanced oral health behaviour, a reduction in self-reported performance impacts and high participant retention.

HABIT-an early phase study to explore an oral health intervention delivered by health visitors to parents with young children aged 9-12 months: study protocol

BACKGROUND

Parental supervised brushing (PSB) when initiated in infancy can lead to long-term protective home-based oral health habits thereby reducing the risk of dental caries. However, PSB is a complex behaviour with many barriers reported by parents hindering its effective implementation. Within the UK, oral health advice is delivered universally to parents by health visitors and their wider teams when children are aged between 9 and 12 months. Nevertheless, there is no standardised intervention or training upon which health visitors can base this advice, and they often lack the specialised knowledge needed to help parents overcome barriers to performing PSB and limiting sugary foods and drinks.Working with health visitors and parents of children aged 9-24 months, we have co-designed oral health training and resources (Health Visitors delivering Advice in Britain on Infant Toothbrushing (HABIT) intervention) to be used by health visitors and their wider teams when providing parents of children aged 9-12 months with oral health advice.The aim of the study is to explore the acceptability of the HABIT intervention to parents and health visitors, to examine the mechanism of action and develop suitable objective measures of PSB.

METHODS/DESIGN

Six health visitors working in a deprived city in the UK will be provided with training on how to use the HABIT intervention. Health visitors will then each deliver the intervention to five parents of children aged 9-12 months. The research team will collect measures of PSB and dietary behaviours before and at 2 weeks and 3 months after the HABIT intervention. Acceptability of the HABIT intervention to health visitors will be explored through semi-structured diaries completed after each visit and a focus group discussion after delivery to all parents. Acceptability of the HABIT intervention and mechanism of action will be explored briefly during each home visit with parents and in greater details in 20-25 qualitative interviews after the completion of data collection. The utility of three objective measures of PSB will be compared with each other and with parental-self reports.

DISCUSSION

This study will provide essential information to inform the design of a definitive cluster randomised controlled trial.

TRIAL REGISTRATION

There is no database for early phase studies such as ours.

Summary of: Mind the gap! A comparison of oral health knowledge between dental, healthcare professionals and the public

INTRODUCTION

The importance of consistent, accurate and unambiguous messages are well documented in oral health promotion literature. Whether the reality of delivering messages in the field fulfils these principle is questionable.

OBJECTIVE

This paper explores the perceptions of dental professionals, healthcare professionals and lay community members with regard to key oral health messages in order to highlight any inconsistencies and knowledge gaps between and within groups for disease risk factors.

METHOD

A questionnaire was administered to individuals who belonged to three groups: dental professionals, healthcare professionals and lay community members. The questionnaire established knowledge regarding risk factors for caries, periodontal disease and erosion.

RESULTS

Thirty-five (57.4%) of the dental group answered the whole questionnaire correctly, with 22 (27.8%) and 9 (5.1%) of the healthcare and lay community group answering the whole questionnaire correctly, respectively. The question of fluoride levels in children's toothpaste was the main reason for incorrect answers in the dental group.

CONCLUSIONS

The results of this survey demonstrate a knowledge gradient from dental professionals through to healthcare professionals and then to lay members of the community. The knowledge base observed in the dental group is reflected in the other two groups as would be expected albeit with a significant gap between each group. As expected the dental professionals are generally well informed, but not as well informed as could be expected.
