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.
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.
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.
Patients with mild skeletal facial asymmetry showed some specific skeletal and dental characteristics. There could be some correlations between these features．.
本研究旨在调查轻度骨骼性面部不对称患者的牙齿及颅面形态特征，并探究轻度骨骼性面部不对称与牙齿异常之间的关系。
选取30例轻度骨骼性面部不对称患者（实验组）和30例面部正常患者（对照组）。所有患者均接受锥形束计算机断层扫描（CBCT）和X线机扫描，使用Winceph软件测量后前位头颅侧位片，使用NNT软件测量CBCT数据。采用SPSS 19.0软件包通过卡方检验、配对t检验和独立样本t检验对结果进行分析。
实验组患者面部、牙齿及第一磨牙牙槽骨的左右两侧存在显著差异。实验组与对照组在下颌牙中线与面部中线的夹角、下颌前平面倾斜度、第一磨牙倾斜度、下颌第一磨牙牙槽骨倾斜度、下颌第一磨牙牙槽骨宽度方面存在显著差异（P<0.05）。颏点偏移、第一磨牙倾斜度和第一磨牙牙槽骨倾斜度之间存在一定相关性。
轻度骨骼性面部不对称患者表现出一些特定的骨骼和牙齿特征。这些特征之间可能存在一定相关性。
