摘　　要：目的利用牙齿磨耗不同的分类方法分别推断上、下颌的牙齿年龄,分析各种方法推断上、下颌牙齿年龄的误差,评价上、下颌牙齿用于年龄推断的准确性。方法采用分级法与数量化法分别对164名18~46岁之间的成年人进行牙龄推断,计算出推断牙龄与实际年龄的误差,输入SPSS软件对误差的数据进行统计学分析。结果分别使用不同方法对上、下颌牙齿磨耗程度进行年龄推断的结果差别不大。结论上、下颌牙齿用于牙齿磨耗推断年龄的准确性无明显差异。Objective To examine the accuracy of different teeth wear classification methods, and analyze the errors yielded by those methods. Methods Different methods were used to estimate the age of 164 adults between 18 to 46 years old to obtain the objective errors. The data was analyzed with SPSS software. Results There was no significant difference in age estimation between the methods using maxillary and mandibular teeth. Conclusion The accuracy of age estimation by examining maxillary and mandibular teeth wear have no disparity.
