摘要
收集206例藏族人牙的磨耗度资料,应用多元逐步回归方法,获得34个推断年龄回归方程。统计分析:r-0.82～0.97;Fs=34～952>F_(0.01);t=21～31>t_(0.01),则P<0.01。本结果为牙的磨耗度推断为藏族人的年龄提供了科学依据。
The authors collected 206 cases of the Zang nationality from Sichuan province, aging 12～84 years old. The total number of the teeth is 5768. By applying the new standard on teeth attrition and multiple stepwise regression 34 equations of the age estimation have been obtained on the maxillary, mandible teeth and teeth groups and single tooth. In order to obtain the convenience of usage, these equations have also been turned into 34 tables in estimation of age. The correlation coefficients are 0.82 to 0.97. The testsingnificance (Fs=34-952>F_(0.01), P<0.01) are highly significat. The scientific basis was obtained to estimate age by the attritin degreet of teeth on the Chinese Zang Nationality
