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.

[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.

Effect of a Person-Centered Course on the Empathic Ability of Dental Students.

Person-centered or patient-centered care (PCC) focuses on the individual's needs and concerns. Although PCC is widely acknowledged as a core value of modern medicine, there has been a lack of research on how dental curricula could engage future dentists in PCC approaches. The aim of this study was to assess the impact of a PCC course on empathy in dental students. A controlled study was conducted with fourth-year dental students in four dental faculties in France in 2014-15. The test group (n=63) received 20 hours of PCC training including arts-based approaches, narrative dentistry activities, and workshops on communication based on the Calgary-Cambridge guide. There was no change in the curriculum of the control group (n=217). Pretest and posttest measures with the Toronto Empathy Questionnaire (TEQ) and Jefferson Scale of Physician Empathy (JSPE) were compared for the two groups. The comparisons showed no significant differences on the TEQ or JSPE (p=0.25 and p=0.08, respectively). However, there was a higher proportion of students with more than an eight-point decrease in TEQ values in the control group (p=0.02). The stabilization of empathic ability in the test group may have counteracted the tendency for natural erosion of empathy among students during their clinical activities. These results suggest that PCC training constitutes a promising approach to developing dental students' empathic ability, but there is a need to assess the effects of such training over longer periods.

[Development and evaluation of a triage tool for patients in a dental emergency unit]. / Construction et évaluation d'un outil d'orientation des patients vers une unité d'urgence odontologique.

OBJECTIVE: This study was designed to develop and evaluate a guidance tool to refer patients with dental emergencies to a hospital dental emergency unit. METHODS: The referring tool was first developed. It was designed to define a waiting timeforpatient management by assessing the clinical signs described by these patients on presentation at the dental care unit. The validity of the tool was then assessed by comparing the waiting time defined by the referring tool to that defined by a practitionerfor 300 patients attending the Emergency Dental Unit in Clermont-Ferrand. Indicators for specificity, sensitivity and the kappa coefficient were used. RESULTS: The referring tool was able to define a waiting timefor 92% of patients. It was able to correctly identify patients needing care "within 24h" (s = 0.84, k = 0.72). Patients who reportedfew symptomswere referred within a "3-7 days" waiting time (s= 0.88, k = 0.62). The tool was less effective for patients needing care within "1-2 days"(s = 0.42, k= 0.41), whose clinical signs were less acute. Specificity exceeded 0.8 in every case. Accordingly, regardless of the waiting time, the use of this tool avoided scheduling appointments for patients who did not need care. The toolfacilitated emergency unit activity, as 50% ofthe appointments could be scheduled beyond 24 hours. CONCLUSION: The metrological characteristics of the referring tool were well adapted to the setting studied.

[Evaluation of an oral health promotion program after one year of implementation in a nursery school]. / Evaluation après un an d'un programme de promotion de la santé orale a l'ecole maternelle.

An oral health promotion programme and study are currently being carried out in 9 nursery schools with children at high risk for cavities located in the deprived neighbourhoods of the city of Clermont-Ferrand (France). The programme's objective is to promote the improvement of tooth brushing habits (2 times/day) and general oral hygiene associated with the use of fluoridated toothpastes. Dental care and dental hygiene visits are also encouraged. In 2005-2006 the programme was implemented in 4 schools; another group of 5 schools constituted a control group. After one year, an evaluation of the process, the programme's effectiveness and short-term outcomes was conducted. The majority of the parents, teachers and children participated in the program but their involvement was limited, with active participation being difficult to achieve. The programme was positive in terms of its prevention component and objective. A significant improvement in children's oral hygiene habits was obtained in the programme group as compared to the control group. However, the care and treatment needs of the children in both groups were not covered, given that one child out of four remained with untreated lesions at the end of the year. These results suggest that here are many barriers that prevent children's access to care which need to be addressed.

Validation of a French version of the Child-OIDP index.

The Child-OIDP index is an indicator of oral health-related quality of life, which has been validated among 12-yr-old children in Thailand. The aim of this study was to assess the reliability, validity, and applicability of this questionnaire among French children. After translation and cultural adaptation, the Child-OIDP was tested on 414 10-yr-old children in France. The children completed the Child-OIDP in face-to-face interviews, were clinically examined, and answered questions evaluating their global self-rated oral health. Parents filled in a questionnaire concerning their socio-demographic background. An oral impact on daily life was reported by 73% of the children. The mean Child-OIDP score was 6.32 [standard deviation (SD) 8.22] and the median was 3.33. The internal reliability was confirmed with a Cronbach's alpha of 0.57. The retest procedure (n = 62) showed a satisfactory reproducibility (r = 0.81, kappa = 0.75). The index was shown to be a valid instrument. Construct validity was satisfactory as the Child-OIDP score increased when the children's perceived oral health decreased. The Child-OIDP score was able to discriminate between different socio-demographic groupings and varied according to dental status. This study showed that the Child-OIDP is applicable for use among children in France. It has promising psychometric properties but further research is required to evaluate its sensitivity to change.
