摘要
①目的探讨国人下颌骨性别差异并找出判别率较高的判别式。②方法对９７例（男６１例，女３６例）东北地区出土的成人下颌骨进行了１５个项目的测量。③结果下颌髁间宽，男１２５．２２±６．０７ｍｍ，女１２０．５３±５．９４ｍｍ；喙突间宽，男９９．２２±５．８７ｍｍ，女９５．２２±５．９９ｍｍ；下颌角间宽，男１０１．６０±５．９１ｍｍ，女９８．０７±５．９７ｍｍ；下颌体长，男７３．８０±４．９６ｍｍ，女７０．９３±４．２９ｍｍ；下颌体高Ⅰ（右），男３１．８７±３．０２ｍｍ，女３０．１５±２．６３ｍｍ；下颌体高Ⅰ（左），男３１．６０±３．２４ｍｍ，女２９．７９±２．５９ｍｍ．以上项目均具有明显的性别差异（ｔ＝２．２５～３．７２，Ｐ＜０．０５，０．０１）。由下颌髁间宽、喙突间宽、下颌体高组成的判别式，判别率最高，达７５．５％．④结论国人下颌骨存在明显的性别差异。由下颌髁间宽、喙突间宽。
Objective In order to study the sexual difference of mandible and find some reasonable discriminant formulae for Chinese. Methods According to traditional anthropometry, 15 measurments on 97 (M 61, F 36) adult mandibles collected in northeast China were measured. Results The bicondylar breadth: M 125.22±6.07mm,F 120.53±5.94mm; intercoronoid breadth: M 99.22±5.87mm, F 95.22±5.99mm; bigonial breadth: M 101.60±5.91mm, F 98.07 ±5.97mm; length of the mandibular body: M 73.80±4.96mm, F 70.93± 4.29mm; height of the mandibular body I(right): M 31.87±3.02mm, F 30.15±2.63mm, Ⅱ(left): M 31.60±3.24mm, F 29.79±2.59mm. All above measurments displayed significant sexual differences. The formula taking in the bicondylar breadth, intercoronoid breadth and height of the mandibular body was most helpful in distinguishing sexes. Conclusion There is significant sexual difference in Chinese mandible. The bicondylar breadth, intercoronoid breadth and height of the mandibular body are most useful factors for sexual diagnosis.
