Sleep medicine education in the United States advanced dental education programs

Dental sleep medicine is an emerging field within dentistry. While limited education in sleep medicine has been reported among US predoctoral dental schools, no study has been conducted among postgraduate dental programs. This study compared the extent and exposure to sleep medicine education among US postgraduate programs in orthodontics, pediatric dentistry, orofacial pain (OFP), general practice residency (GPR), and advanced education in general dentistry (AEGD).

A REDCap survey was distributed among N = 391 US postgraduate programs investigating the nature, content, and modality of sleep education during the 2023-24 academic year.

Among 68 responding programs (43.1% GPR, 18.5% AEGD, 18.5% orthodontics, 12.3% pediatric dentistry, and 7.7% OFP), faculty with sleep training constituted 7.5%, with 2.6% being board certified in sleep medicine. Approximately 41.8% of programs offered sleep medicine courses, with differences among specialties (100% OFP, 42.9% GPR, 37.5% pediatric dentistry, 33.3% orthodontics, 16.7% AEGD; p = 0.032). Didactic teaching comprised 7.8 ± 14.6 h/year (range 0 h/year in 21.5% to 80 h/year in 1.5%), with differences across programs (OFP = 44.0 ± 17.7, orthodontics = 8.7 ± 11.0, GPR = 5.0 ± 8.0, pediatric dentistry = 2.1 ± 1.9, and AEGD = 2.9 ± 5.4; p < 0.001), and constituted the primary modality of instruction (mainly obstructive sleep apnea, bruxism, sleep physiology). Screening and treatment for sleep-related disorders were provided by 35.9% and 37.9% of programs, respectively, with variations among specialties (p = 0.004).

Our findings revealed an average of 7.8 h/year of didactic sleep medicine instruction, which differed across specialties. OFP offered the highest level of didactic and clinical training. These findings emphasize the need for increased dental sleep medicine education to address the increasing involvement of dental professionals in managing sleep-related disorders.
