Identification is an important aspect of forensic medicine. Identification plays an imperative role, especially in highly decomposed bodies, mutilated bodies, and undisclosed and fragmentary human remains. The estimation of sex is an essential parameter of human identification. In forensic anthropometry, sex determination is related to morphometric characteristics of skeletal bones, such as the skull and mandible, clavicle, sternum, scapula, humerus, pelvic bone, sternum, and femur. Since teeth are decay-resistant, conscientious analysis of teeth can accredit reliable sex estimation of an individual, especially when other determinants are fragmented or destroyed.
The aim of the study was to explore the association between sex and buccolingual crown dimensions of teeth.
The study sample consists of 100 volunteer subjects (50 male subjects and 50 female subjects) aged between 20 and 35 years. Alginate was used to take impressions of the teeth and the cast was prepared using pouring by dental stone. Measurements of buccolingual parameters of all the teeth (except the third molars) of both jaws were done on dental casts by using a digital caliper.
Collected data were analyzed using SPSS software (IBM Corp., Armonk, NY) and were outlined as mean and standard deviation (SD). The male and female groups were compared using an independent Student's t-test or unpaired test. The results of this study revealed that 16 out of 28 odontometric parameters (except third molar) of the two groups (male and female) were higher in the male group as compared to the female group (p < 0.05).
Buccolingual odontometric parameters can be used for sex estimation in the North Indian population.
身份鉴定是法医学的一个重要方面。身份鉴定起着至关重要的作用，特别是在高度腐败的尸体、残缺不全的尸体以及未公开的零碎人体遗骸中。性别估计是人体身份鉴定的一个基本参数。在法医人体测量学中，性别判定与骨骼的形态测量特征有关，如颅骨、下颌骨、锁骨、胸骨、肩胛骨、肱骨、骨盆骨、胸骨和股骨。由于牙齿具有抗龋性，对牙齿进行认真分析可以为个体的可靠性别估计提供依据，特别是当其他决定因素残缺或被破坏时。
本研究的目的是探讨性别与牙齿颊舌径尺寸之间的关联。
研究样本包括100名年龄在20至35岁之间的志愿者（50名男性受试者和50名女性受试者）。使用藻酸盐制取牙齿印模，并使用牙科石膏灌注制备模型。通过使用数字卡尺在牙模上对上下颌所有牙齿（第三磨牙除外）的颊舌参数进行测量。
使用SPSS软件（IBM公司，纽约州阿蒙克）对收集的数据进行分析，并以平均值和标准差（SD）进行概述。使用独立样本t检验或非配对检验对男性和女性组进行比较。本研究结果显示，两组（男性和女性）的28个牙齿测量参数（第三磨牙除外）中有16个在男性组中高于女性组（p < 0.05）。
颊舌牙齿测量参数可用于北印度人群的性别估计。
