Sleep-disordered breathing in children and adolescents seeking paediatric dental care in Dubai, UAE

Purpose: This study aimed to evaluate the severity of high-risk SDB in children and adolescents seeking paediatric dental care. Sleep-disordered breathing (SDB) has many untoward consequences that may interfere with children's health and is associated with several risk factors. Methods: In this cross-sectional study, the convenience sample included 65 healthy children and adolescents aged 7–16. High-risk SDB breathing was assessed using the Paediatric-Sleep-Questionnaire consisting of 22 questions. High-risk was defined as a positive response to 33% or more of the questions. The clinical examination included: tonsils' size, Body-Mass Index, orthodontic examination, and enamel defects. Results: In this sample of 65 children with a mean age of 9.75 (± 2.60) years; 36 (55.4%) were boys, and 29 (44.6%) were girls. Overall, 12.3% of children in the sample were at high-risk of SDB, and this was significantly associated with tonsils' size (P = 0.001), Body-Mass Index (P = 0.03), Class-II molar relationship (P = 0.03), and posterior crossbite/s (P = 0.02). Conclusions: This study suggested that approximately 12% of the sample studied were potentially at risk of SDB. Tonsils' size, Body-Mass Index, Class-II molar relationship, and posterior crossbite/s were positively associated with the risk of SDB. Therefore, the importance of investigating the risk for sleep-disordered breathing should not be disregarded.
