Human skull consists of various bones. One of them is mandible which is quite resistant, tough and shows systemic differences in form between individuals of different sex. It resists putrefaction also. There are characteristic features in the mandible that help us to differentiate sex in case of unknown victims like in mass disasters or in case fragmentary remains of the skeleton are found. Analysis of mandible with regard to its features is of great assistance in the determination of sex.
A total of 80 dry mandible bones were collected. Morphological and morphometric parameters were studied to determine their sex. A total of nine parameters, i.e., three non-metric and six metric parameters were observed for each mandible. Data was collected for each parameter.
Among 80 dry mandible bones, 55 were males and 25 were females. 81.2% males bones had a square chin whereas, 80% females had a rounded chin. Gonial flare was everted in 89% males and inverted in 68% females.
Mandible exhibits significant sexual differences. Various morphological and morphometric parameters are essential for sex determination in case of mandible bone.
人类颅骨由多块骨头组成。其中之一是下颌骨，它相当坚固、坚韧，且不同性别的个体在形态上存在系统性差异。它也能抵抗腐败。下颌骨具有一些特征，有助于我们在大规模灾难等未知受害者的情况下，或者在发现骨骼碎片遗骸时区分性别。对下颌骨的特征进行分析，对确定性别有很大帮助。
共收集了80块干燥的下颌骨。研究形态学和形态计量学参数以确定其性别。每块下颌骨观察了总共九个参数，即三个非计量参数和六个计量参数。收集了每个参数的数据。
在80块干燥的下颌骨中，55块为男性，25块为女性。81.2%的男性下颌骨有方形下巴，而80%的女性有圆形下巴。89%的男性下颌角外翻，68%的女性下颌角内翻。
下颌骨表现出显著的性别差异。各种形态学和形态计量学参数对于下颌骨的性别鉴定至关重要。
