O-HEALTH-EDU: A viewpoint into the current state of Oral Health Professional education in Europe: Part 1: Programme-level data.

INTRODUCTION: Current legislation leaves Oral Health Professional (OHP) education open to wide interpretation and may result in significant variation in educational practice and resultant professional attributes across Europe. Data regarding the current state of OHP education across Europe is limited. The aim of Part 1 of this series is to provide programme-level data for Primary Dental Degree Programmes, Dental Hygiene and Postgraduate Education. METHODS: A 91-item questionnaire was developed following the Delphi method. The questionnaire and the Articulate glossary of OHP education terms were developed concurrently to facilitate a common understanding of language. Piloting was performed in multiple stages and included institutions internal and external to the research group. The questionnaire was uploaded online and converted to a data hub, allowing dental schools to control their own data and update the data provided whenever they wish. All ADEE member schools (n = 144) were invited to provide data. Forty questions relating to school details, Primary Dental Degree Programmes, Dental Hygiene and Postgraduate Education were included in this part of the series. RESULTS: Seventy-one institutions from 25 European countries provided data between June 2021 and April 2023, which represents a response rate of 49.3% of ADEE members. Programme-level data for Primary Dental Degree Programmes, Dental Hygiene and Postgraduate Education is presented including programme length, funding, languages and fees, student numbers and demographics, student admission and selection processes and permission to practice after graduation. CONCLUSION: This series of papers, as far as the authors are aware, are the first attempts to build a comprehensive picture of the current state of OHP education in Europe. A comprehensive view of the state of OHP education in Europe is not yet available but the O-Health-Edu data hub provides a means for all education providers in Europe to contribute data to reach this goal. It is anticipated that the data hub will be updated and built upon over time to continually establish a clearer picture of the state of OHP education in Europe.

O-Health-Edu: A viewpoint into the current state of oral health professional education in Europe: Part 2: Curriculum structure, facilities, staffing and quality assurance.

INTRODUCTION: Oral health professional (OHP) education is likely to vary across Europe in accordance with an EU directive that is open to broad interpretation. It is not clear how OHP curricula are structured or delivered across Europe. The objectives of Part 2 of this paper series are: (i) to provide an overview of common practices in curriculum structure, the availability of facilities, staffing (faculty) and quality assurance processes and (ii) to consider how the existing programme structures align to stakeholder guidance documents. METHODS: A total of 27 questions from a 91-item questionnaire were used for this manuscript. The questionnaire was developed following the Delphi method to establish consensus from a group of experts. Members of the research team and colleagues from other countries in Europe completed a multi-step piloting process. An online data hub was created to allow the respondents to be data controllers and respond to the questionnaire. ADEE member schools (n = 144) were invited to provide data. RESULTS: Totally, 71 institutions from 25 European countries provided data between June 2021 and April 2023, which represents a response rate of 49.3% of ADEE members. Data on curriculum approaches, teaching methods, integration of topics of interest, clinical education, staff-student ratios, access to facilities and new technologies, teaching staff (faculty) and quality assurance processes are presented for Primary Dental Degree Programmes. CONCLUSION: To the best of our knowledge, this series of papers are the first attempts to provide a comprehensive overview of OHP education in Europe. Results showed that the majority of European dental programmes are engaged in providing innovative and scientifically grounded education in order to develop quality future OHPs. Nevertheless, significant variability in the delivery of clinical education across the European OHP schools was notable in this dataset. A comprehensive view of the state of OHP education in Europe is not yet available but the O-Health-Edu data hub provides a means for all education providers in Europe to contribute data to reach this goal. It is anticipated that the data hub will be updated and built upon over time to continually establish a clearer picture of the state of OHP education in Europe.

Platform for Better Oral health in Europe / La plateforme pour la santé orale en Europe

The Platform for Better Oral Health in Europe brings together five European organizations (Council of European Chief Dental Officers, Association for Dental Education in Europe, European Association of Dental Public Health, Pan European-International Association For Dental Research, Oral Health Foundation-UK) along with eighteen other associated European or national organizations. The platform aims to encourage oral health promotion and the prevention of oral diseases as fundamental components of good general health. The aim is thus to strengthen oral health promotion in Europe through integrating oral health into the relevant public health policies. It also aims to address the issue of oral health inequality, particularly among vulnerable populations such as children and adolescents, older adults, and people with particular needs. The platform is therefore a European-level resource for providing evidence-based information on best practice in oral health promotion and for guiding oral health policies. It also works to reinforce communication at the European level between stakeholders, policy makers, health professionals, and the public, in order to improve awareness of oral health issues.

La « plateforme pour une meilleure santé orale en Europe ¼ réunit six associations européennes (Council of European Chief Dental Officers, Association for Dental Education in Europe, European Association of Dental Public Health, Pan European-International Association For Dental Research, Oral Health Fondation-European Federation of Periodontology) en lien avec dix-neuf organisations européennes ou nationales associées. Elle a pour objectif d'encourager la promotion de la santé orale et la prévention des maladies bucco-dentaires en tant qu'éléments fondamentaux d'une bonne santé générale. L'objectif est aussi de renforcer la politique de promotion de la santé orale en Europe, y compris par l'intégration de la santé orale dans des politiques de santé publique pertinentes. Il s'agit également de prendre en compte la question des inégalités en matière de santé orale, notamment au sein des populations vulnérables comme les enfants et les adolescents, les personnes âgées et les personnes ayant des besoins spécifiques. La plateforme constitue ainsi une ressource au niveau européen pour fournir des informations fondées sur des preuves concernant les meilleures pratiques en promotion de la santé orale et pour l'orientation des politiques en matière de santé orale. Elle travaille aussi à développer les relations au niveau européen avec les parties prenantes, les décideurs politiques, les professionnels de santé, le public, afin d'améliorer la prise en compte des enjeux concernant la santé orale en Europe.

The COVISTRESS oral-health study: Dental-care access in France during the COVID-19 pandemic / Accès aux soins dentaires pendant la pandémie de Covid-19 en France : l'enquête COVISTRESS-santé orale

The COVID-19 pandemic led to an interruption in dental-care services during the initial lockdown period. This study assesses the impact of this period on the perception of oral health and accessibility to dental care in France. A questionnaire survey was carried out (COVISTRESS.ORG) to study the stress and health behaviors of adults before, during, and after the first lockdown, i.e., at the time of the response. An "oral health" questionnaire assessed changes in the perceived difficulties for accessing dental care. Between November 2020 and April 2021, 339 adults completed the "oral health" section. The perceived-difficulty-in-accessing-dental-care score (on a scale of 0 to 100) was 21.6 ± 26.7 before the pandemic, 52.9± 39.5 during lockdown, and 38.1± 35.3 after it. Before the pandemic, this score was linked to an unfavorable perception of oral health and to difficulties in accessing health care. During lockdown, the score was associated with high dental care needs (RR=4.1; CI95%=1.2­13.8), and perceived difficulties in accessing the health care system (5.06; 1.8­14.1), particularly transport difficulties (3.0; 1.1­9.1). The factors explaining the change in difficulties from before to after the lockdown differ according to when the assessment was done. This study demonstrates the negative impact of the pandemic on perceived difficulties for accessing dental care, within a population with few socially disadvantaged people.

La pandémie de Covid-19 a entraîné une interruption des soins dentaires lors du premier confinement. Cette étude évalue les répercussions de cette période sur la perception de la santé orale et de l'accès aux soins dentaires en France. Une enquête par questionnaire a été menée (COVISTRESS) pour étudier le stress et les comportements de santé des adultes avant, pendant et après le premier confinement, soit au moment de la réponse. Un questionnaire « santé orale ¼ a évalué l'évolution de la perception des difficultés d'accès aux soins dentaires. Entre novembre 2020 et avril 2021, 339 personnes ont répondu au volet « santé orale ¼. Le score de difficulté perçue d'accès aux soins dentaires (0 à 100) passe de 21,6 ± 26.7 avant la pandémie à 52,9 ± 39,5 pendant le confinement et à 38,1 ± 35,3 après celui-ci. Avant la pandémie, ce score est lié à une perception défavorable de la santé orale et aux difficultés d'accès aux soins de santé. Pendant le confinement, le score est lié à un besoin élevé en soins dentaires (RR=4,1 ; IC95 %=1,2-13,8), à la perception de difficultés d'accès au système de santé (5,06 ; 1,8-14,1), notamment des difficultés de déplacement (3,0 ; 1,1-9,1). Les facteurs expliquant l'évolution des difficultés avant et après le confinement diffèrent selon le temps d'évaluation. Cette étude montre les répercussions négatives de la pandémie sur la perception de l'accès aux soins, dans une population intégrant peu de personnes socialement défavorisées.

Influence of an oral health promotion program on the evolution of dental status in New Caledonia: A focus on health inequities.

New Caledonia is a sui generis collectivity of overseas France situated in the south Pacific Ocean. Geographical and social inequalities are superimposed on ethnic disparities with high prevalence of chronic diseases such as oral diseases. In 2012, the health agency has evaluated the children's health status. Then, an oral health promotion program was developed in 2014. Another study was conducted in 2019 in New Caledonia to appreciate the evolution of children's oral health. A sample of 488 9-years-old children was randomly selected. Dental status was clinically recorded, families and children answered questionnaires about oral health determinants. The methodology (sampling, study variables…) was similar to the one used in the 2012 study. Multivariate mixed-models were conducted to compare 2012 and 2019 dental status and to explore the determinants of caries experience in 2019. Results indicated that caries prevalence and experience decreased between 2012 and 2019, with nonetheless various trends depending on the province or type of indexes. The number of carious lesions (d3t + D3T) in 2019 was used as an outcome variable in four models. Model 1 integrated social variables; ethnicity was found to be the only significant determinant. Model 2 was related to oral health care; participation in the program & and access to oral health care was found to be significant. For oral health behaviours (model 3), tooth brushing frequency and consumption of sugary snacks were significant risk factors. In a final model with significant variables from the previous models, ethnicity, accessibility of oral health care, number of sealed molars, consumption of sugary snacks remained explanatory factors. Five years after the implementation of the oral health promotion program, positive changes in oral health have been observed. However, health equity is still an issue with varying health status depending on ethnicity, behavioural factors and accessibility to oral health care.

O-Health-Edu: A vision for oral health professional education in Europe.

This consensus paper reports on the process of developing a renewed vision for Oral Health Professional (OHP) education across Europe, and forms part of a larger EU-funded collaborative Erasmus+ project, "O-Health-Edu." The vision aligns with the World Health Organisation milestones (2016) and resolutions (2021), and EU4Health programme (2020) objectives - and projects 20 years into the future, to 2040. This longitudinal vision takes a multi-stakeholder perspective to deliver OHP education that acts in the best interests of both students and patients, and sits within the context of a wider strategy for general health. Included, it is an infographic to help communicate the vision to various stakeholders of OHP education.

ARTICULATE: A European glossary of terms used in oral health professional education.

INTRODUCTION: The Erasmus+O-Health-EDU project aims to gain a comprehensive view of oral health professional (OHP) education in Europe, through the development of web-based surveys and online toolkits. A glossary to facilitate a common language through which academic teams could cooperate and communicate more accurately was identified as a key need within the project. The aim of ARTICULATE was thus to create a shared language, with a European focus, for terms and concepts used in the field of OHP education. METHODS: The methodology was developed from those published for construction of other glossaries with a circular and iterative process: the creation of content and definitions by a group of experts in OHP education, the testing of "fitness for purpose" of the content, and stakeholder consultation. All creation steps were followed by refinements based on testing results and stakeholder comments. The final glossary was then launched as an online resource including a built-in mechanism for user feedback. RESULTS: The scope and structure of the glossary were mapped out at a workshop with 12 dental education experts from 7 European countries. A total of 328 terms were identified, of which 171 were finally included in ARTICULATE. After piloting with a close group of other colleagues, the glossary was opened for external input. Thirty European Deans or Heads of Education assessed the definition of each term as "clear" or "not clear." A total of 86 definitions were described as "clear" by all individuals. Terms deemed unclear by at least one individual were revisited and changes made to 37 of the definitions. In conjunction with the launch of the glossary, a range of stakeholder organisations were informed and asked to participate in an open global consultation by providing feedback online. Since its launch in June 2021, the ARTICULATE website (https://o-health-edu.org/articulate) has had an average of 500 visits/month. To promote community ownership, forms embedded on the ARTICULATE webpage allow users to give feedback and suggest new terms. A standing taskforce will meet regularly to consider amendments and make changes to ensure that the glossary remains a relevant and up-to-date resource over time. CONCLUSION: ARTICULATE is a unique, evolving, online glossary of terms relating to OHP education, created as a resource for all interested OHP educators. The glossary is a key output of the O-Health-Edu project, which relies on a comprehensive vision of OHP education to address the future oral health needs of the European population.

Validation of the French version of COHIP-SF-19 among 12-years children in New Caledonia.

BACKGROUND: Assessment of oral health-related quality of life is now associated to clinical indicators in epidemiological studies. This study aimed at validating the French Short Form of the Child Oral Health Impact Profile (COHIP-SF-19) and assessing the impacts of oral diseases among schoolchildren in New Caledonia (NC). METHODS: A sample of 12-years-old children (n = 971) was selected in 2019 in NC using a random, stratified, and clustered sampling technique. Children filled the French COHIP-SF-19 questionnaire. Information on sociodemographic characteristics, oral hygiene habits, perception of oral health problems were also collected through self-administered questionnaires or from the schools' database. Dental status (dental caries, gingival status, and dental functional units) was clinically recorded at school by four calibrated examiners. Cronbach's alpha and intraclass correlation coefficients (ICC) were calculated. Kruskal-Wallis tests and spearman correlations were used along with multilevel mixed models taking into account the cluster and examiner effects. A confirmatory factor analysis was conducted and sensitivity analyses were performed. RESULTS: Among the 693 children examined, 557 children were included. Oral diseases were frequent in the study population 40% had dental caries and 55% presented gingivitis. The COHIP scores ranged from 7 to 76 (57.9 ± 9.96) with 96.4% of the children having experienced oral health problems, 81.7% reporting functional impacts and 90.5% socio-emotional impacts. Overall, the French COHIP-SF-19 showed satisfactory psychometric characteristics. Internal consistency was high (Cronbach's alpha = 0.80) and reproducibility excellent (ICC = 0.9). Discriminant and concurrent validity were adequate. Indeed, children with less optimal social situation, impaired dental status, declaring severe dental problems or difficulties in accessing oral health care showed lower COHIP-SF-19 scores. Factor analyses suggested a four-component structure with identification of a new domain (self -image) and changes in the repartition of the items within the original domains. Sensitivity analyses showed similar results for children with partial or complete answers in the COHIP questionnaire. CONCLUSIONS: The French COHIP-SF-19 showed satisfactory psychometric characteristics and allowed to identify the high impacts of oral diseases in New Caledonian children, namely for socially deprived children.

Translation and preliminary validation of a French version of an ageism scale for dental students.

BACKGROUND AND AIM: The World Health Organization considers ageism an important barrier to age-appropriate care for older adults. A new ageism scale for dental students (ASDS) has been validated in the United States, Brazil, Greece and Romania. The aim of this study was to validate a French version (ASDS-Fr). METHOD AND MATERIALS: The 27-item ageism scale was translated from English into French, and its content validity was investigated using the content validity index. The translated version was completed by 180 dental students in the Dental School of Clermont-Ferrand in France. Principal component analysis (PCA) was performed and internal consistency reliability was calculated. RESULTS: The final PCA model resulted in 10 items and three components that together accounted for 57.2% of the overall variance. The first component contained four items that point to a negative view of older adults; the second contained three items that appeared to reflect an absolving of responsibility for providing care to older adults; and the third contained three items that deal with gerodontology education. CONCLUSIONS: This preliminary validation of the ASDS-Fr produced a new 10-item scale with three components with acceptable validity and reliability.

O-HEALTH-EDU: A scoping review on the reporting of oral health professional education in Europe.

INTRODUCTION: The variability in oral health professional education is likely to impact on the management of oral health needs across Europe. This scoping review forms the initial part of a larger EU-funded collaborative Erasmus + project, 'O-Health-Edu'. The aim of this scoping review is to investigate how oral health professional education in Europe is reported. METHODS: The PRISMA and Arksey & O'Malley methodological frameworks for scoping reviews were used to guide reviewers in answering the research question "How is oral health professional education reported in Europe?". The search strategy encompassed published literature searches, internet searches and further searching of relevant documents from educational organisations, regulators and professional bodies. Once the search strategy was developed, it was sent to key stakeholders for consultation. Sources were reviewed by two authors (JD, JF) and included in the review if they reported on oral health professional education in Europe. RESULTS: A total of 508 sources were retrieved from all of the searches. A total of 405 sources were excluded as they did not report on the topic of interest, leaving 103 sources that reported on oral health professional education in Europe. Handsearching the references of published sources lead to a further 41 sources being screened, of which, 15 were included. In total, 33 duplications were removed and the final number of included sources was 85. The average year of publication for the included sources was 2007, with sources most commonly published in journals dedicated to dental education. Surveys represented the most common form of reporting. From the data obtained, four broad themes of reporting were evident: dental education at a programme level, dental education at a discipline level, other oral health professional education, and postgraduate education and continuous professional development. CONCLUSION: The reporting of dental and oral health professional education in Europe is limited. Whilst there are many useful documents that provide guidelines on dental education, there is limited knowledge on how education is implemented and delivered. There is a greater need for comprehensive educationally driven programme-level data on oral health professional education across Europe.

Consommation de soins dentaires préventifs en région Centre-Val de Loire : une étude rétrospective.

CONTEXT: The demography of dentist-surgeons in the Centre-Val de Loire region is far inferior to the national average and characterized by many territorial inequalities of health. The aim of this study is to provide details concerning the dental hygienic care-seeking consumption habits in this region based on one dental care treatment, dental scaling, which allows for the mechanical elimination of dental plaque in order to prevent periodontal diseases. METHOD: This retrospective study is based on data from several databases of the National Health Insurance Cross-Schemes Information System (Sniiram) for the year 2016, analyzed by the Statistical Institute of Liberal Health Professionals. RESULTS: It can be observed that less scaling treatments have been sought out in this region in comparison with metropolitan France and certain territories which also face difficulties in terms of care treatment offers and scaling treatment inferior to the regional average. Although the care offer is unequally distributed, it seems to have little influence on the number of treatment acts consumed per patient and notably scaling treatments. Inversely, indicators of wealth or poverty do have an impact on treatment consumption HBJD001. CONCLUSION: This study suggests that the consumption of scaling treatment is independent from the dental care offers, but linked to the social gradient of the population. It points to the deficit in the consumption of this treatment in comparison to metropolitan France. The potential role of the HBJD001 treatment as a marker of the trajectory of preventive health care as well as the necessity of the adjustment of the zones determined by the ARS are put forward.

COVID-19: The immediate response of european academic dental institutions and future implications for dental education.

The COVID-19 pandemic has had an immediate and dramatic impact on dental education. The Association of Dental Education in Europe decided to carry out an investigation to assess the immediate response of European Academic Dental Institutions. An online survey was sent to both member and non-member dental schools to investigate the impact on non-clinical and clinical education, assessment and the well-being/pastoral care measures implemented. The preliminary findings and discussion are presented in this paper, for the responses collected between the 25 March and 5 April 2020. The survey at this time of publication is ongoing, and detailed results can be accessed https://adee.org/covid-19-european-dental-education%E2%80%99s-immediate-response.

Implementation and impact of a dental preventive intervention conducted within a health promotion program on health inequalities: A retrospective study.

BACKGROUND: The objective of this retrospective survey was to evaluate after one year, the conditions and impacts of a dental sealant intervention conducted in New Caledonia, within a health promotion program. A greater or at least equivalent quality and impact of the intervention was expected for children living in socially deprived regions with the greatest health needs. METHODS: The study population was the schoolchildren, aged 6 years in 2016, who benefited from the dental sealant program (n = 2532). The study sample was randomly selected in 2017 from that population (n = 550). The children's dental status was evaluated at school in 2017 and compared with that recorded in 2016 during the sealant intervention allowing the calculation of the retention rates and one-year carious increment on first permanent molars. Socio-demographic variables (gender, public/private school) and conditions of sealant placement (school/dental office, presence of a dental assistant) were recorded. The carious increment was explained using a mixed multiple random-effects regression. A mediation analysis was conducted to assess the respective contributions of the retention rates and the region of origin on caries increment. RESULTS: The participation rate was very high (89%) and on average, children had 83% of their dental sealants present after one year, 31% fully and 52% partially present. Caries increment varied depending on the sealant retention rate as well as on the region (North, South, Islands). The mediation analysis showed that living in a deprived area (The Islands) was a strong determinant for high caries increment particularly when the retention rates were low. CONCLUSIONS: This study showed a high participation rate and acceptable effectiveness as measured with the one-year retention rates, for a fissure sealant intervention conducted in real-life conditions and integrated in a large health promotion program. Nevertheless, the intervention was not effective enough to totally balance the influence of health determinants, especially in socially deprived sectors characterized by greater dental needs.

Oral health and chemotherapy act as cofactors in malnutrition in the elderly with other cancers than head and neck malignancies.

OBJECTIVES: This study explores whether the chemotherapy regimen has a role in inducing oral health problems and malnutrition in elderly patients with other cancers than head and neck malignancies. MATERIAL AND METHODS: An observational cross-sectional study was designed to compare the relationships between oral health and nutritional status between four groups of elderly differing in cancer or chemotherapy regimen. Data were collected using a questionnaire including the Mini-Nutritional Assessment (MNA), the Geriatric Oral Health Assessment Index (GOHAI) and questions about perception of xerostomia. The oral examinations recorded the number of functional dental units (PFU) and the presence of oral lesions. RESULTS: The sample comprised 46 patients receiving chemotherapy, 48 patients on a non-chemotherapy regimen, 45 persons in complete remission not under treatment and 53 non-cancer patients. Oral health perception was significantly worse in chemotherapy patients. They reported limiting the kinds of food they consumed, the discomfort felt when eating and took medications for oral pain. Oral lesions were frequent in chemotherapy participants. Nutritional status was related to the cancer treatment regimen (OR = 4.17; p value = 0.017), the presence of oral lesions (OR = 4.51; p value = 0.003), perception of xerostomia (OR = 3.54; p value = 0.012), the number of PFU (OR = 2.51; p value = 0.046) and GOHAI score (OR = 1.617; p value = 0.019). CONCLUSION: The presence of oral lesions and the chemotherapeutic regimen were highly associated with nutritional status in older patients with cancer. CLINICAL RELEVANCE: Dental professionals should be asked to intervene preventively and per-therapy to optimise oral health status in elderly patients with other cancers than head and neck malignancies.

[Oral health inequalities: Determinants of access to prevention and care in France]. / Inégalités en santé orale : déterminants de l'accès à la prévention et aux soins en France.

INTRODUCTION: Oral diseases are unequally distributed according to a social gradient, which now constitutes a major public health problem. Acting against oral health inequalities requires a better understanding of the underlying mechanisms in order to identify the appropriate solutions to improve access to oral health promotion and dental care for deprived populations. METHODS: A patient-centered model of health care access, describing the ideal interactions between individuals and the health care system was applied to the field of oral health in the French context. This model defines access to health care as the result of interactions between individuals and the health care system, in which health needs are perceived, health care is sought, health care structures are accessed and effectively used. Analysis is based on quantitative and qualitative bibliographic data acquired through an explanatory sociological approach. RESULTS: Socially deprived populations face many barriers preventing their access to dental care: the need for dental care is not necessarily perceived, and, when perceived, dental care is not immediately sought, accessibility to dental care structures is difficult and dental attendance is erratic. CONCLUSION: This review provides information to decision-makers in order to support regional health policies and to help implement public health strategies according to the principle of proportionate universalism. Two axes for action were identified, namely to integrate oral health promotion interventions within health promotion programmes and to gradually reorganize the dental care system to make it more accessible to everyone.

Social inequalities in oral health in a group of older people in a Middle Eastern country: a cross-sectional survey.

BACKGROUND AND OBJECTIVE: The percentage of Lebanese older people has increased considerably. Given that Lebanese seniors are marginalized in the health policy-making process, we suggest a high social inequality in oral health that has not been studied so far. The purpose of our study was to describe and compare oral health status in a group of Lebanese older people according to their socioeconomic status (SES) MATERIALS AND METHODS: Participants were recruited from three different primary health care clinics in Beirut, Lebanon. Data were collected from an administered questionnaire that included sociodemographic variables, perception of oral health, and regular dental visits. Oral examination included the number of missing and decayed teeth, the prosthetic status, and the number of functional dental units (FUs). The SES of the participants was determined by educational level, previous or actual work, and neighborhood level. RESULTS: 264 participants aged 71.4 ± 6.27 years (64.7% female) were included in the study. Regular dental visit, dental status, FU, and oral health perception were significantly related to the participants' place of residence, educational level, and work. Moreover, the mean number of missing teeth (p = 0.048) and decayed teeth (p = 0.018) was significantly elevated in the low SES. CONCLUSION: There is a clear socioeconomic inequality in oral health among the Lebanese older people. Further researches should explore the potential contribution of psychosocial and behavioral factors in explaining these disparities.

Common risk indicators for oral diseases and obesity in 12-year-olds: a South Pacific cross sectional study.

BACKGROUND: Despite the increasing need to prevent obesity and oral diseases in adolescents worldwide, few studies have investigated the link existing between these conditions and their common risk factors. This study aims to evaluate the oral health and weight status of New Caledonian Children (aged 6,9,12 years) and to identify, amongst 12-year-olds, risk indicators that may characterize the groups of children affected by oral diseases, obesity or both diseases. METHODS: This survey evaluated in 2011-2012 the oral health and stature-weight status and related risk indicators in a national representative sample of 6, 9 and 12 years-old children in New Caledonia. Dental status, chewing efficiency, height, weight and waist circumference were clinically recorded at school. The body mass index (BMI) and the waist to height ratio (WtHR) were calculated. For BMI the WHO Cut-offs were used. Twelve years-old participants responded to a questionnaire concerning socio-demographic and behavioural variables. For statistical analysis, the Clinical Oral and Global Health Index (COGHI) was developed and used. Twelve years-old children were categorised into four groups; Oral Diseases (ODG), Obesity (OG), Obesity and Oral Diseases (ODOG) and a Healthy Group (HG). A multivariate analysis was conducted using mixed-effects multinomial logistic regression models. RESULTS: Prevalence of overweight and obesity was greatly increasing from 6 years (respectively 10.8% [8.8;13.3] and 7.8% [6.0;9.9]) to 12 years (respectively 22.2% [19.9;24.7] and 20.5% [18.2;22.9]) and one third of the 12-yr-olds had an excess of abdominal adiposity. At age 12, 36.6% of the children were healthy (HG), 27.3% had oral diseases (ODG), 19.7% were obese (OG) and 16.5% had both conditions (ODOG). Geographical location, ethnicity, tooth-brushing frequency and masticatory disability were significant risk factors for the OG, ODOG and ODG groups. Ethnicity and masticatory impairment were common risk indicators for the association of oral diseases and obesity. CONCLUSIONS: In NC health promotion programs should be specifically addressed towards Native populations who are particularly exposed to oral diseases and obesity, integrating a multiple risk factors approach, in order to prevent the onset of chronic diseases in adulthood. The impact of masticatory ability on children's weight status is a major issue for future research.

A Rasch Analysis between Schizophrenic Patients and the General Population.

BACKGROUND: The aim of this study was to test the General Oral Health Assessment Index Questionnaire (GOHAI) items for differential item functioning (DIF) according to demographic characteristics (gender, age) and mental health status (schizophrenic disorders versus general population) using Rasch analysis. METHODS: This is a cross-sectional study using aggregated baseline data from a validation study of the GOHAI in the French general population (GP) and similar validation study in persons with schizophrenia (PWS). DIF was tested using the Partial Credit Model. DIF were estimated in different groups of patients. RESULTS: The cohort comprised 363 persons: 65% were female, 83% were 25-45 years old and 30% were PWS.Five of the 12 items exhibited DIF. DIF effects were observed with schizophrenia for 3 items, with age for 3 items and with gender for 1 item. The variable "age" gave a significant explanation of the latent variable: the latent variable decreased with age (-0.40±0.08-p<0.001 for each increase of the age of 10 years). This decrease represented an effect size of 0.27 which can be qualified of a small to medium effect. The status of the individuals (GP versus PWS) and the gender did not significantly explain differences in the values of the latent variable. CONCLUSION: The GOHAI scores may not be comparable across sub-groups defined by health status, age and gender without accounting for DIF. In the future, other studies should explore this way with other Oral Health related Quality of Life assessment tools and populations with mental illness.
