Sleep disordered breathing and oral health-related quality of life in children with different skeletal malocclusions

Abstract

ABSTRACT Objective To evaluate the relationship among different skeletal malocclusion patterns, sleep-disordered breathing (SDB) and children’s oral health-related quality of life (OHRQoL). Methods Two hundred-five patients were divided into three groups, considering skeletal malocclusion. Parents completed the Pediatric Sleep Questionnaire (PSQ) on behalf of the patients, who completed the 14-question version of the Oral Health Impact Profile (OHIP-14). Results SDB was observed in 10.7% of children. The overall prevalence of snoring, difficulty breathing during sleeping, mouth breathing, and dry mouth on awakening was 8.78%, 7.31%, 36.09%, and 37.07%, respectively. However, there was no significant difference in OHIP-14 parameters among the skeletal groups. A positive correlation was found between OHIP-14 and PSQ and was significant in Class I and III. Conclusion Although there was no significant difference, SDB risk and sleep quality were found as most to least problematic, in the following sequential order: Class II > Class III > Class I.
