School of Dentistry Faculty Research and Publications

Obstructive sleep apnea (OSA) is a common and potentially serious sleep disorder characterized by repetitive episodes of complete or partial upper airway obstruction during sleep. These obstructions result in a reduction or cessation of airflow, leading to oxygen desaturation, and disruptions in sleep patterns.1,2 Common symptoms of OSA include loud snoring, gasping or choking during sleep, excessive daytime sleepiness, morning headaches, and irritability. Obstructive sleep apnea is often associated with other medical conditions, such as obesity, hypertension, cardiovascular disease, and diabetes. Diagnosis typically involves polysomnography to assess the frequency and severity of apneic episodes.
