AbstractIntroductionDental sleep medicine (DSM) is an emerging discipline that studies the oral and maxillofacial causes and consequences of sleep‐related problems. DSM is of upmost importance given the major medical challenge it represents. Therefore, to verify whether the future generation of dentists would be ready to face this challenge, the main objective of this study was to assess the degree of involvement of the French dental schools in teaching DSM at the undergraduate level.Materials and MethodsAll 16 dental schools in France were asked to participate in the study by answering to an online survey concerning the DSM curriculum during the 2018–2019 academic year. The survey was addressed to the head of the dental school and/or to relevant course coordinators and contained 10 questions related to the type, content and amount of DSM teaching to undergraduate dental students.ResultsNine of the 16 (56.2%) French dental schools responded to the questionnaire. All these nine reported the inclusion of DSM in their undergraduate curriculum. The total average hours dedicated to teaching DSM was 5.6 h (SD 4.2; range 1–15 h). Seven of the 9 dental schools spent most of their DSM curriculum teaching time in the fifth year. All of them reviewed obstructive sleep apnoea and sleep‐related bruxism and covered some topics related to therapies for sleep‐related breathing disorders, such as the use of oral appliance.ConclusionThe results of this survey showed that, although the average hourly volume is relatively high, the DSM teaching in French dental schools appeared to be non‐standardised, heterogeneous and often lacunar. It is therefore essential to develop a common curriculum and implement it in all dental schools to provide undergraduate students a comprehensive and updated teaching in DSM.
