A Frontal Cephalometric Evaluation of Asymmetry in Class II Subdivision Malocclusions
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 11
Abstract
Introduction: The purpose of this study was to determine whether Angle class II subdivision malocclusions have skeletal or dental asymmetries between the class II and class I sides. Methods: Thirty subjects with Angle class II subdivision malocclusions were assessed with postero-anterior cephalometric radiographs. Paired t-test was applied on paired measurements for statistical analysis of class II and class I sides. Non Parametric Chi-sq test was applied on unpaired measurements. Results: There was statistically highly significant association for mandibular dental midline deviation towards class II sides. On the other hand maxillary dental midline showed statistical significance for coincidence with facial midline. No statistically significant difference was found between class II side and class I side. Conclusions: The etiology of class II subdivision malocclusions is dentoalveolar. Distal positioning of mandibular molars is responsible for producing asymmetry between class II and class I sides
