摘要
目的:建立恩施土家族苗族自治州(以下简称恩施州)各民族Bolton指数正常参考值标准,为本州错畸形患者的诊断、设计和预后分析提供客观科学的参考数据。方法:选择恩施州汉族、土家族和苗族接近理想正常标准模型各80副,男、女各40副,测量各样本的牙冠宽度。计算每个样本的Bolton指数,然后运用SPSS软件处理数据并进行统计学分析。结果:统计学分析表明,恩施州各民族间Bolton指数差异无显著性,男女间Bolton指数差异无显著性,民族和性别不存在交互效应。恩施州人群合并计算后Bolton指数为:前牙比为(79.82±1.76)%,后牙比为(104.38±1.93)%,全牙比为(92.59±2.12)%。结论:恩施州Bolton指数可用统一标准。与其他地区和民族公布的Bolton指数相比,存在一定差异。
Objective：To determine the Bolton radios of different populations with normal occlusion in Enshi Tujia and Miao Autonomous Prefecture and to provide the reference for diagnosis,design and prognostic analysis in orthodontic treatment.Methods：Two hundred and forty pairs of dental casts was selected from Han,Tujia and Miao population with 80 pairs each（40 male and 40 female）.Anterior,posterior and overall Bolton ratios were determined and analyzed.Results：No signifiant differences of anterior,posterior and overall Bolton ratios were found among populations,genders and interaction of population and gender.The total anterior,posterior and overall Bolton ratios of Enshi populations were（9.82±1.76）%,（104.38±1.93）% and（92.59±2.12）%,respectively.Conclusion：The total anterior,posterior and overall Bolton ratios could be applied to all populations in Enshi.
