Abstract

Background: The determination of age and sex is required for forensic practice and medicolegal purposes. Because the mandible is typically recovered intact, it plays a crucial role in determining sex. Orthopantomogram X-rays can be used to thoroughly examine the mandible. The availability of a large number of antemortem orthopantomograms could be extremely beneficial in terms of evaluating and developing population-specific sex determination standards. Objectives: To evaluate the usefulness of the mandibular ramus in sex determination by evaluating linear and angular measurements of the mandibular ramus on digital panoramic radiographs. Methods: An analytical cross-sectional study was conducted on 216 digital orthopantomogram from March 2021 to June 2021 in Kantipur Dental College. A convenient sampling technique was used to collect the radiographs. Mandibular parameters were traced using Image J Software, and angular and linear parameters were calculated. Radiographs with high image quality and sharpness of patients with full permanent dentition, no radiographic evidence of trauma were included in the study. Descriptive analysis was done using IBM SPSS Statistics for Windows, version 20 (IBM Corp., Armonk, N.Y., USA). The measures were compared using an Independent t-test, and the results were subjected to discriminant function analysis. Results: The male’s vertical parameters were found to be greater than the female’s. The coronoid height was shown to be the most dimorphic using discriminant analysis. The overall accuracy of the mandibular parameters was 63.4%. Conclusion: Mandible can be used as an adjunct in sex determination.
下颌参数作为性别的预测指标:一项数字骨断层成像研究
背景:年龄和性别的确定是法医实践和医学法律目的所必需的。由于下颌骨通常完好无损,因此它在决定性别方面起着至关重要的作用。骨断层x射线可以用来彻底检查下颌骨。在评估和制定特定人群的性别确定标准方面,大量的死前骨断层摄影的可用性可能是非常有益的。目的:通过评估数字全景x线片上下颌支的线性和角度测量,评价下颌支在性别确定中的作用。方法:对Kantipur牙科学院2021年3月至2021年6月的216张数字骨层析成像进行横断面分析研究。采用方便的抽样技术收集x线片。使用Image J软件对下颌参数进行跟踪,并计算角度参数和线性参数。具有高图像质量和清晰度的完整恒牙列患者的x线片,无创伤的x线片证据被纳入研究。使用IBM SPSS Statistics for Windows, version 20 (IBM Corp., Armonk, n.y., USA)进行描述性分析。采用独立t检验对测量结果进行比较,并对结果进行判别函数分析。结果:男性的垂直参数大于女性。判别分析表明,冠高度是最具二态性的。下颌参数的总体准确度为63.4%。结论:下颌骨可作为性别判定的辅助工具。
