性别估计是人类身份识别的“三大”之一，是产生未知死者生物学特征的过程中的重要方面。人体测量和牙齿测量的方法，利用某些标志之间的距离测量通常用于区分两种性别。牙齿是人体中最坚固和保存最完好的部分，研究表明，一个未知个体的性别可以通过测量来估计。本研究进行了分析的性别差异的基础上的牙弓尺寸的两个颌骨在印度人口。正确理解牙弓的尺寸不仅有助于法医学的身份识别，而且有助于牙科医生的牙齿修复，并量化前牙粘接义齿的选择。在307名参与者的牙模中记录了犬齿、前磨牙和双颌磨牙的牙弓尺寸。比较男性和女性的牙弓尺寸，并生成逻辑回归模型来估计性别。受试者操作特征分析，以找出潜在的估计性别的所有牙弓尺寸在两种性别。据观察，上颌磨牙间距离II给出了最好的结果，在估计性别。性别鉴定的准确性被认为是增加，因为我们去远端从犬齿到磨牙在每个颌骨;最小的犬齿间的距离和最大的距离之间的第二磨牙。根据牙弓尺寸进行性别鉴定的准确率为72.7%~ 86.5%。从牙弓尺寸估计性别的模型可以用于骨骼遗骸的情况下。
Sex estimation is one of the "big three" of human identification and is a vital aspect of the process of generating biological profile of unknown deceased. Anthropometric and odontometric methods that utilize measurement of distances between certain landmarks are commonly employed to differentiate between the 2 sexes. Teeth are the most robust and well-preserved parts of the human body, and studies have shown that the sex of an unknown individual can be estimated using their measurements. The present study was carried out to analyze the sex differences based on the dental arch dimensions of both the jaws in an Indian population. A proper understanding of dental arch dimensions not only help forensic odontologists in human identification, but also help dental practitioners in teeth restoration, and to quantify selection of anterior teeth in bonding of dentures. The dental arch dimensions of the canines, premolars, and the molars of both the jaws were recorded in dental casts of 307 participants. Comparison of the dental arch dimensions of males and females was done and logistic regression models were generated to estimate sex. Receiver Operating Characteristic analysis was done to find out the potential to estimate sex for all the dental arch dimensions in both the sexes. It was observed that maxillary intermolar II distance gave the best results in estimating the sex. The sexing accuracy is seen to increase as we go distally from canines to molars in each jaw; minimum for intercanine distance and maximum for distance between the 2nd molars. The sexing accuracy from dental arch dimensions was found to be between 72.7% and 86.5%. The models derived for estimation of sex from dental arch dimensions can be used in cases of skeletal remains.
