摘要/Abstract

摘要： 本文以华南人103例17—73岁男性颅骨的709个臼齿为材料,研究了上下颌臼齿磨耗度与年龄的关系。将磨耗度分为九级,统计分析结果表明,华南人臼齿的磨耗度与年龄关系是密切相关的,这种相关关系,能够作为估计华南人颅骨年龄的标准。第一臼齿与第二臼齿的磨耗平均年龄比率是M1∶M2=6∶6.9;磨耗度与年龄的相关系数M1为0.91,M2为0.90,均为高度相关。并得出磨耗度的平均年龄及95％置信区间(见表3)。华南人下颌臼齿的磨耗比上颌臼齿的磨耗稍大(61.5％)。

Abstract: The attrition of molars with relation to age in 103 male Southern Chinese skulls was studied. The age of the skulls ranges from 17 to 73 years. Altogether 709 first and second molars were studied. The degree of attrition was divided into nine grades. The results were subjected to statistical analysis.
It is concluded that the degree of the attrition of the molars is closely related to age in the Southern Chinese skulls and that it can be used as a criterion for estimating age of adult skulls.
The second molar, due to its later eruption, wears more slowly than the first molar and the age ratio between the first and second molars is about 6:6.9.
The mean age and its 95% confidence interval for each grade of the attrition of the molars were given in table 3.
The degree of attrition of lower molars of the Southern Chinese skulls are higher than that of the upper molars.
