摘要
本文采用Scott定义的臼齿磨耗级别系统,对陶寺、上马、延庆三组人牙的第一、第二臼齿磨耗情况进行观察,并通过主轴回归分析对其磨耗速率进行比较和讨论。在经济类型上,陶寺和上马属于农业经济,但陶寺的狩猎在其经济生活中占有一定地位;延庆畜牧业则比较发达。分析表明三组人牙均表现出臼齿磨耗速率下颌快于上颌的特点,而在性别上没有明显差异。在组间差别上,上马组的磨耗速率似略快于其他两组。磨耗速率的组内、组间差异与上下颌牙齿咬合关系、口腔咀嚼生理以及不同经济文化古人群的食物构成等差异有关。
First and second molar attrition scores of three ancient populations Taosi, Shangma and Yanqing were recorded using Scott＇s dental attrition record system. Major axis regression analysis was used in molar attrition rate comparison. The ages of three groups date from late Neolithic to Spring and Autumn Period. These three groups were also distinguished by their economic systems： pastoralism in Yanqing and agriculture in Taosi and Shangma. Results show that there are attrition rate differences between groups in upper and lower jaws but no difference between male and female. The reason for these may be the occlusal relationships of upper and lower molars, dental physiological function of the teeth, and the difference in economic subsistance between the groups.
