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。
Objective To establish a method for determining the sex of the mandible in Chinese with a high degree of disability. Methods The mandibles of 160 bones with known sex in 8 provinces and cities in China (including 108 males and 52 females, ranging in age from 18 to 75 years) were measured. The mandibular angle of the left mandible was selected, Mandibular branch of the two measurements of 15 indicators, the use of SPSS software for statistical analysis, screening significant indicators of gender differences, the use of discriminant analysis to establish a highly dismembered mandible to determine the gender of the discriminant equation. Results A total of 44 discriminative criteria were found for the highly discriminated mandibular disability. Three groups of mandibular angles, twenty five mandibular branches, and 16 mandibular angles and mandibular branches were determined. The maximum discriminant rate of male SDD was 69.4% for males and 75% for females, with a total score of 70.6%. The discriminant rate of mandibular branch was 77.8% for males and 80.8% for females, and 75.6% for males. Mandibular angle and mandible The highest gender discrimination rate of joint judgment was 75 0% for males, 84 6% for females and 75 6% for males. CONCLUSIONS This study is applicable to criminal cases as well as natural disasters such as fires and plane crashes, as well as the sex determination of highly-fractured mandibles in archeological work.
