Eur J Paediatr Dent. 2011 Dec;12(4):267-71. Prevalence of malocclusion in preschool and primary school children with habitual snoring and sleep-disordered breathing.

AIM: Our research aimed to find out whether it was possible to establish a correlation between instrumental polysomnographic variables in children with Sleep Disordered Breathing (SDB) and their clinical dentofacial records. MATERIALS AND METHODS: 197 children, 116 (59%) male and 81 (41%) female, age range 0 to 12 years, with a clinical history highly suggestive for SDB were enrolled. All patients underwent full-night Poly-Mesam examination and a specific clinical orthodontic evaluation. A comparison between polysomnographic variables  and clinical orthodontic variables was made. RESULTS AND CONCLUSION: OSAS can not be diagnosed by the paediatric dentist only  by performing a single clinical orthodontic examination of oral cavity, but a polysomnography is essential and, if this should point out any pathology referring to SDB, a cranial lateral cephalometry will then be required.
