Obstructive sleep apnea is common, serious, and largely undiagnosed, and dental professionals are well positioned to recognize patients at risk. This 2-hour webinar introduces the fundamentals of dental sleep medicine. It defines the spectrum of sleep-disordered breathing, from snoring to obstructive sleep apnea, and reviews key sleep study terms such as AHI. Participants will learn practical in-office screening, including validated questionnaires and oral and craniofacial findings, and the major medical comorbidities associated with OSA. The course also clarifies the dentist’s scope of practice and offers strategies for communicating and collaborating with sleep physicians to support appropriate diagnosis and care.
