Objectives: To assess the proportion of individuals who were aware of a link between diabetes and oral health, who reported that their dentist was aware of their diabetes status, as well as associated explanatory factors, and to examine how this information relates to the use of dental care. Methods: In the 2007 Entred study, 8,926 adults with diabetes residing in mainland France were randomly selected. A questionnaire was used to gather information from 3,894 individuals identified as having type 2 diabetes regarding their sociodemographic characteristics, health status, and insights into their knowledge and practices regarding oral health. Results: Nearly 70% of the participants were unaware of the links between diabetes and oral health. More than 40% reported that their dentist was not aware of their diabetes status, and among them, nearly 40% believed that diabetes was not the dentist’s concern. Awareness of the links and the fact that the dentist was informed of the diabetes were positively associated with the use of dental care. Conclusion: Our results suggest that significant improvements are needed in terms of informing people with diabetes about the links between diabetes and oral health, as well as in dentists’ awareness of their patients’ diabetes status.
