Aim: To review various comprehensive centers on the diagnosis and treatment of sleep-disordered breathing (SDB), highlighting the valuable role that oral appliances can play in managing this disorder. Background: Obstructive sleep apnea (OSA) is an emerging medical condition that is attracting the interest of healthcare experts. This ailment has been found to impact a considerable portion, approximately 20%, of the population. It is characterized by recurrent episodes of breathing cessation during sleep, followed by brief awakenings. Sleep disorders can significantly impact children's sleep quality among which OSA is the most prevalent. Enlargement of the tonsil stands as one of the primary causes of SDB in children. Surgical removal of the tonsils often serves as an effective treatment for SDB. Results: The correction of tongue thrusting, speech-related concerns, and abnormal swallowing patterns often necessitates speech therapy, particularly myofunctional therapy. For older children, an occlusal splint can be provided to mitigate bruxism. Various mandibular advancement (MA) appliances are available to prevent or reduce upper airway collapse during sleep. These devices have proven effective in managing the condition OSA for patients who are unable to tolerate surgical interventions. Conclusion: Dentists are gaining a growing awareness of the significance of SDB and their involvement in treating this condition using oral appliances. Their unique access to examining the oral cavity positions dentists to play an active role in identifying children with enlarged tonsils and referring them for sleep evaluations. Clinical significance: Dentists, among the healthcare professionals involved in the care of children, are often well-positioned to identify cases of adenotonsillar hypertrophy. Consequently, dentists can play a vital role in recognizing and managing such cases through the use of oral appliances. This becomes particularly relevant for patients who decline surgical options or those with structural abnormalities that can benefit from myofunctional appliances.
