Identification and determination of sex of unknown human skeletal remains has been one of the most challenging tasks for forensic dentistry. The purpose of this study was to determine the gender from the analysis of mental foramen on panoramic radiographs in a north Indian population.
One hundred radiographs were selected for the analysis of mental foramen. Tangents were drawn to the superior and inferior borders of the foramen and perpendiculars were drawn from the tangents to the lower border of the mandible (S-L and I-L). The data obtained were tabulated and subjected to statistical analysis.
The average values of S-L and I-L were significantly higher in males than in females, while the distances for the right and left sides of an individual were almost similar in both the male and the females group, and the results were non-significant.
The distances from the mental foramen to the lower border of the mandible exhibit sexual dimorphism in the north Indian population.
识别和确定未知人类骨骼遗骸的性别一直是法医牙科学中最具挑战性的任务之一。本研究的目的是通过对印度北部人群全景X线片上颏孔的分析来确定性别。
选择100张X线片用于颏孔分析。画出颏孔上下边界的切线，并从切线向下颌骨下缘作垂线（S-L和I-L）。将获得的数据制成表格并进行统计分析。
男性的S-L和I-L平均值显著高于女性，而在男性和女性组中，个体左右两侧的距离几乎相似，结果无统计学意义。
在印度北部人群中，颏孔到下颌骨下缘的距离存在性别差异。
