【摘要】 目的建立中国人高度残碎下颌骨的性别判定方法。方法测量了国内 8个省市的已知性别的 16 0具尸骨的下颌骨 (其中男性 10 8例 ,女性 5 2例 ,年龄范围 18～ 75岁 ) ,选择了下颌骨左侧的下颌角、下颌支两部位的 15项指标的测量值 ,利用SPSS软件进行统计分析 ,筛选出性别差异显著的指标 ,使用判别分析方法 ,建立高度残碎下颌骨判定性别的判别方程。结果得到高度残碎下颌骨性别判别方程共计 4 4组 ,下颌角 3组 ,下颌支2 5组 ,下颌角和下颌支联合判定 16组。下颌角性别判别方程的最高性别判别率男性 6 9 4 % ,女性 75 % ,综合70 6 % ,下颌支最高性别判别率男性 77 8% ,女性 80 8% ,综合 75 6 % ;下颌角与下颌支联合判定的最高性别判别率男性 75 0 % ,女性 84 6 % ,综合 75 6 %。结论本研究可适用于刑事案件以及火灾、飞机失事等自然灾害事件以及考古工作中的高度残碎下颌骨的性别判定。更多还原

【Abstract】 Objective To establish a method of sex determination from fragmentary and incomplete mandibulae in Chinese population.Methods 15 parameters from left mandibular angle and mandibular ramus were measured on each pair of mandibula of 160 known Chinese skeletons(108 males and 52 females, age range is 18～75), which come from eight provinces of China. Data obtained were subjected to Statistical Package for the Social Sciences (SPSS) discriminant function analysis, and measurements that showed different significantly were selected for constructing the sex discriminant functions.Results 44 sex discriminant functions for fragmentary and incomplete mandibulae in left were generated. It showed that the high average accuracy of the mandibular angle was 70.6%, 69.4%, for male and 75% for female.According to mandibular ramus, it is 75.6%, 77.8% in male group and 80.8% in female group.When using a combination of mandibular angle and mandibular ramus, Sex correct rate is 75.6%, 75.0% in male and 84.6% in female.Conclusion~It showed the functions acquired were effective and reliable in the sex determination from fragmentary mandibula.This study can be used for sex determination in murder cases, fire disaster, airplane crashed and archaeology as well.更多还原
