Social disparities in health are particularly evident in the field of oral health. The INSEE Decennial Health Survey conducted in 2002–2003 provides data on the general population regarding health status and healthcare utilization. However, it is important to note the limitations of this type of survey due to its self-reporting methodology and the nature of the variables collected. The analyses presented focus on the sample of individuals aged 18 and older in the Île-de-France region, comprising 5,820 people. Among the study population, 13.5% reported a dental problem, and 12.9% consulted a dentist during the survey period. The results highlight disparities in the prevalence of dental problems, in the use of dental care, and in the treatments administered, depending notably on individuals’ supplemental coverage. Furthermore, the reasons for visiting the dentist are primarily symptomatic. This raises questions about the understanding and adoption of preventive messages. The importance of regular dental visits appears to be poorly integrated into healthcare habits. (R.A.)
