下颌骨是最大和最硬的面部骨骼，在法医和物理人类学领域比其他骨骼更好地保持其形状。下颌骨可以用来区分种族群体和性别。我们研究了102个韩国人的下颌骨的形态特征。在下颌骨的13个非测量项目中，最能区分性别的特征是下颌骨下缘的轮廓：男性（68.1%）的下颌骨以摇杆形为主，而大多数女性（84.6%）的下颌骨呈直形。此外，颏区的形状在性别之间也有差异：大多数男性的下巴形状通常是双叶或方形（91.7%），而女性的下巴是方形（45.5%）或尖形（54.5%）。本研究中，男性和女性的阳性预测值分别为92.5%和73.7%。因此，本研究所采用的下颌骨非测量分析方法可用于性别判别。
The mandible is the largest and hardest facial bone and retains its shape better than other bones in the forensic and physical anthropologic field. The mandible can be used to distinguish among ethnic groups and between sexes. We examined the morphological characteristics of the mandibles of 102 Koreans of either sex. Of 13 nonmetric items of the mandible, the characteristic that best allowed the sexes to be distinguished was the contour of the lower border of the mandible: rocker-shaped mandibles predominated in males (68.1%), whereas most females (84.6%) exhibited a straight mandible. In addition, the mental region was shaped differently between the sexes: the shape of the chin in most males was generally bilobate or square (91.7%), whereas the chin in females was either square (45.5%) or pointed (54.5%). In this study, the positive predict values of male and female were 92.5% and 73.7%, respectively. Therefore, the nonmetric method used to analyze the mandible in this study can be used for sex discrimination.
