Sex determination of skeletal remains forms part of archaeological and medicolegal examinations. It is an aspect of forensic odontology. Forensic odontology primarily deals with identification, based on recognition of unique features present in an individual's dental structures. Correct sex determination limits the pool of missing persons to just one half of the population.
Purpose of this study is to evaluate the existence of sexual dimorphism and variation in left and right maxillary first molars using bucco-lingual and mesio-distal dimensions in population of Sirmour District, H.P.
Base sample comprised 100 subjects (50 males and 50 females) of an age group ranging from 17 to 25 years.
Unpaired t-test.
It was observed that the comparison of mean values of bucco-lingual and mesio-distal parameters showed highly statistically significant differences between males and females, measured both intraorally and on study casts. There were no significant differences between the mean values of both the parameters on the left side as compared to right side.
The study concludes that sexual dimorphism is population specific. Among Himachali people, mesio-distal dimensions and bucco-lingual dimensions of first molar can aid in sex determination.
骨骼遗骸的性别鉴定是考古和法医学检查的一部分。它是法医牙科学的一个方面。法医牙科学主要基于对个体牙齿结构中独特特征的识别来进行身份鉴定。正确的性别鉴定将失踪人员的范围限制到仅占人口总数的一半。
本研究的目的是利用喜马偕尔邦锡尔穆尔区人群上颌第一磨牙的颊舌径和近远中径，评估性别二态性的存在以及左右上颌第一磨牙的差异。
基础样本包括100名年龄在17至25岁之间的受试者（50名男性和50名女性）。
非配对t检验。
观察到，颊舌径和近远中径参数平均值的比较显示，在口腔内测量和在研究模型上测量时，男性和女性之间均存在高度统计学显著差异。与右侧相比，左侧两个参数的平均值之间无显著差异。
该研究得出结论，性别二态性具有人群特异性。在喜马偕尔人中，第一磨牙的近远中径和颊舌径有助于性别鉴定。
