摘要/Abstract

摘要： 本文对97例华南人M~I的磨耗度、牙指数和年龄三者之间的关系进行了深入探讨。并由此而提出以牙磨耗度和牙指数为两个变量的三元回归方程。比较分析结果表明,三元相关系数高于其它二元相关系数,三元回归方程的标准估计误差低于其它二元回归方程的标准估计误差。因而,以三元回归方程式比单纯以牙指数或牙磨耗度作为变量的二元回归方程式估计年龄准确。

Abstract: The materials investigated were 97 maxillary first permanent molars of South Chinese.
The authors have studied the relationship among the degree of tooth attrition, the tooth index and the age of 97 M1. A trinal regression formula with two variables, the degree of tooth attrition and the tooth index, was obtained. The values of the correlation coelfieient and the standard estimation error show that the trinal regression formula is better than the dual regression formula for estimating age.
