摘要:

目的 通过对牙齿非测量表型出现率的多元统计学分析和比较,探讨中国汉族和壮族人群牙齿表型的表现特点及与世界人群之间的关系。  方法 2015~2019年,在河南省、江苏省和广西壮族自治区壮族和汉族共采集1785例(分别为674例、547例、388例和176例)样本的10项牙齿非测量表型,与已发表的世界人群数据进行主成分分析(PCA)、多维尺度分析(MDS)以及邻接网络分析等。  结果 东亚人群可明显划分为东北亚和东南亚两大类群,其中汉族和壮族人群均与东北亚人群接近,而与东南亚人群距离较远;汉族人群内部也存在一定的南部、北部和中部的差异。  结论 东亚地区人群确实存在中国型齿和巽他型齿两种牙齿形态类型,中国汉族和壮族人群的牙齿表型均更接近于中国型齿。

Abstract:

Objective To investigate the relationship between the Han, Zhuang and the world populations by comparing the frequency of dental non-metric traits.   Methods From 2015 to 2019, ten dental non-metric traits were sampled from He’nan, Jiangsu and Guangxi Zhuang Autonmous Region, with sample size of 1785(674 He’nan, 547 Jiangsu, 388 Guangxi Han, 176 Guangxi Zhuang). Principal component analysis, multidimensional scaling and neighbor network were carried out.   Results East Asian populations could be clearly divided into two major groups, Northeast Asian and Southeast Asian. Han and Zhuang populations were close to the Northeast Asian populations, but were far from the Southeast Asian populations. There were also some north-south differences within Han populations.   Conclusion Both Sundadonty and Sinodonty are existed in East Asian populations. Han and Zhuang populations dental non-metric traits are closer to the Sinodonty.

Key words: Han, Zhuang, Dental non-metric traits, Principal component analysis, Multidimensional scaling, Neighbor network, Adult
