摘要
本文应用首创的牙齿磨耗分度法—平均磨耗度法(简称“均度法”)对94例东北人的518颗磨牙磨耗程度与年龄的关系进行了初步研究。材料年龄范围为15岁～71岁。经直线回归分析得到4个牙齿磨耗度与年龄关系的回归方程式。统计及回代结果表明,均度法能较以往方法更客观、更全面、更科学地反映整个牙齿的磨耗情况,推断出的年龄更加准确,且可避免某些咬关系对推断年龄的影响。
The newest method of the graduation of molar attrition degrees, the averageof attrition degrees (AAD), was described. 518 molar were collected from 94cadavers and dried skulls in the northeast China. The results indicated thatAAD method can further reflect the attrition condition of the whole toothobjectively, completely and scientifically. It is a valuable means of practicein the field of forensic medicine and physical anthropology.
