摘　　要：目的探讨青铜铁器时代新疆、内蒙古地区人群下颌骨第一磨牙(M1)的磨耗特点。方法根据磨耗程度进行分级,将新疆(77例)、内蒙古(123例)地区的牙齿磨耗进行比较,并同时对比近代人群(云南、华北共134例),用SPSS13.0软件对磨耗级别分数进行均值计算和各组间差异的显著性检验。结果青铜铁器时代的新疆、内蒙古人群牙齿磨耗度都大于近代人群,提示当时食物可能较近代人坚硬。新疆的牙齿磨耗度大于内蒙古地区,可能反映了食物结构、经济方式的差异。新疆人群牙齿磨耗度左右侧相似,性别差异显著,内蒙古人群牙齿磨耗也是左右侧相似、性别差异显著,提示这可能是青铜铁器时代牙齿磨耗的共性,但还需更多遗址标本来检验。结论青铜铁器时代的牙齿磨耗大于近代,新疆、内蒙古人群牙齿磨耗存在差异。Objective To aware tooth wear of mandibular first molar （ M, ） in Bronze-Iron Ages from Xinjiang amt Inner Mongolia. Methods Tooth wear of M1 from Xinjiang （ n = 77） and Inner Mongolia （ n = 123） human mandibles was recorded, and then comparisons were made among groups using SPSS 13.0 software. Results Tooth wear of Xinjiang and Inner Mongolia people was more obvious than modern hmnan, which might indicate that food in Bronzc-lron ages was much rougher. Tooth wear in Xinjiang was more obvious than that in Inner Mongolia. The tooth wear from Xinjiang and hmcr Mongolia had some common traits： there was no big difference in M1 tooth wear between left and right sides, and male＇ s tooth wear was more obvious than female. Conclusion Tooth wear in Xinjiang is more obvious than in Inner Mongolia, and the difference may be related to food, economic types, etc.
