摘　　要：对245只恒牙的牙齿磨耗程度、邻面接触区面积、牙根透明、继发性牙本质、牙骨质厚度、牙根吸收、牙位、性别与年龄的关系进行多元回归分析,表明与年龄间有高度显著性差异(P<0.01)的指标依次为:继发性牙本质、牙根透明、牙齿磨耗度、牙骨质厚度、邻面接触区面积,而牙根吸收、牙位、性别则无。本文还计算出多元逐步回归公式,讨论了各指标在法医学中的应用价值。The relation between age sex and attrition, peridentalattachment area, root transparency, secondary dentin, cementum, root resorption,tooth position of 245 permanent teeth was studied by the multiple regressionanalysis. The results showed that the attrition, peridental attachment area, roottransparency, secondary dentin, cementum are all significant variables for agedetermitation analysis (P<0.01), while the root resorption, tooth position andsex are not (P>0.05). In this article, the application value of the above variablesin forensic are discussed and the multiple regression formulas are obtained.
