目的探讨青铜铁器时代、近代人群下颌骨第1磨牙齿冠面4个区域的磨耗特点。方法将青铜铁器时代(大同、陇县共35例)、近代(云南、华北共195例)人群下颌骨第1磨牙齿冠面分为4个区域,根据磨耗程度进行分级,然后比较各个区域的磨耗级别,并对比近代人群与青铜铁器时代人群。结果青铜铁器时代磨牙4个区域的磨耗都大于近代人群,近代人群与青铜铁器时代人群下颌磨牙4个区域的磨耗都表现为区1最大,区2最小,左右侧结果一致。结论下颌磨牙4个区域的磨耗大小关系为:区1>区3>区4>区2,这种大小关系可能至少从青铜铁器时代就开始形成了。

OBJECTIVE: To study the wear characteristics of four regions of the crown of the mandibular first molar in modern age in bronze iron era. Methods The coronal surface of the first mandibular molar in bronze age (Datong, Longxian, 35 cases) and the modern (195 cases in Yunnan and North China) groups were divided into four regions according to their degree of wear. Then, Wear level, and contrast with the modern crowd and bronze iron age crowd. Results The abrasion of 4 areas of the bronze iron age was greater than that of the modern population. The abrasion of the 4 areas of the mandibular molar in the modern crowd and the bronze iron age showed the largest area 1, the smallest area 2 and the same results on the left and right sides. Conclusion The relationship between the wear rate of the four regions of mandibular molar is as follows: Area 1> Area 3> Area 4> Area 2, which may be formed at least from the Bronze Age.
