Association of orofacial dysfunction and sleep disordered breathing among Indian primary school children.

Introduction: Sleep-disordered breathing (SDB) ranges from partial obstruction of the upper airway resulting in snoring to total upper airway obstruction leading to obstructive sleep apnea. The impairment in the dynamics of the stomatognathic system is termed as orofacial dysfunction. This study investigates the prevalence of orofacial dysfunction and sleep-disordered breathing in primary school children and identifies their correlation.
