Abstract

Abstract: PURPOSE: The purpose of this study was to investigate the dental and craniofacial morphological characteristics in patients with mild skeletal facial asymmetry, and to investigate the relationship between mild skeletal facial asymmetry and dental anomalies. METHODS: Thirty patients with mild skeletal facial asymmetry (experimental group) and 30 patients with normal faces (control group) were selected. All patients were scanned by cone-beam computed tomography (CBCT) and X-ray machine, Winceph software was used to measure the posteroanterior cephalometric radiographs, NNT software was used to measure the CBCT data. The results were analyzed by Chi-square test, paired t test and independent sample t test using SPSS 19.0 software package. RESULTS: There were significant differences between the left and right sides of faces, teeth and alveolar bone of the first molar in the experimental group. The angle of mandibular dental midline and facial midline, the inclination of the frontal mandibular plane, the inclination of the first molar, the inclination of alveolar bone of the mandibular first molar, the width of alveolar bone of the mandibular first molar showed significant differences between the experimental group and the control group (P<0.05). There are some correlations among menton deviation, inclination of the first molar and alveolar bone of the first molar. CONCLUSIONS: Patients with mild skeletal facial asymmetry showed some specific skeletal and dental characteristics. There could be some correlations between these features.
