Introduction:
Dental Sleep Medicine (DSM) has gained increasing relevance in the management of sleep-related breathing disorders, particularly obstructive sleep apnea (OSA), the most prevalent respiratory disorder in sleep medicine. Given the key role of orthodontists and pediatric dentists in early diagnosis and multidisciplinary management, integrating DSM into postgraduate curricula is essential. This study aims to assess current knowledge and interest in DSM among postgraduate students in Orthodontics and Pediatric Dentistry, as well as their perspectives on incorporating diagnostic tools, clinical sessions, and practical training in hospital sleep units.

Materials and Methods:
A structured survey was distributed among postgraduate students from Orthodontics and Pediatric Dentistry programs. The questionnaire consisted of two sections. The first one, Current Knowledge of DSM and OSA ( awareness of DSM and its applications in dental practice, familiarity with OSA symptoms, risk factors, and pathophysiology, understanding of the role of oral appliances in OSA management, previous academic exposure to DSM topics and self-assessed confidence in identifying OSA-related signs in patients). The second one, interest in Learning and Curriculum Integration (willingness to receive further training in DSM, interest in incorporating diagnostic tools, such as home sleep tests and cephalometric analysis, into postgraduate education, support for including clinical sessions on DSM in postgraduate curricula and interest in participating in practical training within hospital sleep units).

Results:
Fourteen postgraduate students responded to the survey, including 12 from Orthodontics and 2 from Pediatric Dentistry. The findings revealed that most students had limited knowledge of DSM, with only a few reporting previous academic exposure to OSA-related topics. While awareness of oral appliance therapy was moderate, confidence in identifying OSA-related signs was low. However, there was strong interest in further education on DSM, with the majority expressing a willingness to incorporate diagnostic tools, clinical sessions, and practical hospital-based training into their postgraduate curriculum.

Conclusion:
Despite limited prior exposure to DSM, postgraduate students in Orthodontics and Pediatric Dentistry demonstrate a strong interest in integrating DSM education into their training. These findings highlight the need for structured curricular reforms to enhance postgraduate competency in managing sleep-related breathing disorders. Further studies with larger cohorts are recommended to optimize DSM education in postgraduate dental programs.
