目的 建立新疆维吾尔族儿童正常硬组织的X线头影测量的正常值 ,并研究其颅面结构的性别特征和种族特征及其增龄性变化。方法 按正常标准选取 10 5名维吾尔族儿童 ,分别摄取标准头颅侧位片 ,选择DOWNS ,WYLIE分析法测量项目 2 0项 ,图形数值化仪采集标志点 ,计算机完成各项测量项目及统计计算。结果 得到了维吾尔族儿童的X线头影测量正常值 ,表明颅面结构的角度测量在正常男女间无显著差异 ,而线距的测量有些项目在男女间有显著差异。颅颌面深度及高度随生长发育而增大 ,骨侧貌空度逐渐减少。结论 维吾尔族儿童颅颌面结构与汉族同龄儿童有显著差异 ,维吾尔族儿童牙弓突度小 ,下切牙较直立 ,下颌向前向上逆时针旋转 ,呈 Щ类面型特征
Objective To establish the normal values of Cephalometrics of normal umbilicus in Uygur children in Xinjiang and to study the gender and ethnic characteristics and age-related changes of craniofacial structures. Methods A total of 105 Uyghur children were enrolled according to the criteria of normal . The subjects were divided into standard cephalometric slices, DOWNS and WYLIE were used to measure 20 items, and the digitizer was used to collect the marks. The computer completed all the measurement items and statistical calculations . The results obtained Uighur children's X-cephalometry normal, indicating that the angle measurement of craniofacial structure in the normal no significant difference between men and women, and the measurement of some of the items in the gap between men and women were significantly different. The depth and height of cranio-maxillofacial area increased with the growth and development, while the osteoporosis gradually decreased. Conclusion The craniofacial structure of Uygur children is significantly different from that of the Han children of the same age. Uygur children have less dental arch, lower incisors are more upright, and the lower jaw rotates forward and upward counterclockwise
