摘　　要：目的：对新疆地区维吾尔族恒牙初期正常牙合睁部形态以及发育状况进行测量分析，为维吾尔族提供正常腭部形态参考指标。方法：收集符合纳入标准的新疆地区维吾尔族恒牙初期正常牙牙合膏模型，按照年龄以及性别进行分组，测量9项腭部相关指标，用SPSS17．0统计软件对各组数据进行统计分析。结果：13～15岁组中，第一前磨牙间腭宽度以及第二前磨牙间腭宽度，男女性别之间差异具有统计学意义（P〈0．05）；16～17岁组中，第二前磨牙间腭高以及第一磨牙间腭宽度，男女性别之间差异具有统计学意义；LSD-t检验结果显示维吾尔族恒牙初期腭部形态各项指标男女各年龄组之间差异均不具有统计学意义；维、汉民族之间多项腭部形态指标差异具有统计学意义。结论：维吾尔族恒牙初期腭部形态具有明显性别差异，均为男性大于女性，但未发现增龄性变化，维、汉恒牙初期腭部形态之间种族差异明显。Objective To study the morphological characteristics of palatal growth and obtain the norms in early permanent dentition of Uyghur population at Xinjiang, China. Methods The samples were selected from Uyghur population who fulfilled the inclusion criteria.measurements were made on nine anatomical landmarks which represented the palatal morphology.All age groups were statistically compared using SPSS 17.0 software. Results In 13-15 age group,we found the palatal width at the first and second premolars had statistical significance, in 16-17 age group, the palatal height at the second premolars and the palatal width at the first premolars showed statistical significance, however we couldn＇t find any statistical difference between age groups by LSD-t test, Many differences between Uyghur population and han population. Conclusion The palatal morphology at an early permanent dentition stage is significantly affected by gender in Uyghur population,males showed increased palatal widths and heights as compared to their female counterparts, but no affect of age was noticed on palatal growth durinq this developmental stage.
