Effects of obstructive sleep disorfers on dental growth in children: a case control study
Obstructive sleep disorders and their effects on dental and maxillofacial growth has long been debated. Adenotonsillar hypertrophy as the most common cause of Obstructive sleep disorders with its consequent impact on dental growth has recently gained greater attention and its treatment may help prevent or reverse these effects.
In this corss-sectional study 120 children were enrolled.60 patients assigned to undergo adenotonsillectomy for obstructive sleep disorders were compared with 60 children without obstructive sleep disorders. Both groups were matched in terms of gender and age. Dental casts and measurements with caliper were used.Crowding of upper and lower teeth, anterior open bite, posterior cross bite, overjet, class II malocclusion, width of upper and lower dental arches were documented and compared.
Differences were found in crowding of upper and lowerteeth, anterior open bite, posterior cross bite, overjet, class II malocclusion and width of upper and lower dental arches.
This study suggests the effects of obstructive sleep disorders on dental growth, probably due to the long term impact of the position of the head, mandible and tongue to keep the airway open in oral breathing.
