Determination of sex is one of the most important and crucial steps in forensic science. Sexual dimorphism using odontometric analysis is found to vary in different populations making it necessary to attain values of a specific population which helps the identification possible. This present study attempts to establish sexual dimorphism using odontometric analysis in Odisha population.
A total of 200 subjects (100 male and 100 female) between ages 18 and 25 years were included in the study. Intraoral Mesiodistal (MD) and Buccolingual (BL) dimensions of 28 teeth (maxillary and mandibular) excluding third molar were taken using digital Vernier calipers. Data were charted and decrypted and statistical analysis was done using SPSS Software version 20.
Our study showed larger dimensions of tooth in males when compared to females (maxillary right and left central incisor, 1 and 2 molar). Interestingly, reverse dimorphism was also observed in few teeth.
The results of the present study showed that the linear (MD and BL) dimensions of teeth played a major role in the determination of gender in individuals. The variations or reverse dimorphism could be a result of geographic variations.
性别鉴定是法医学中最重要且关键的步骤之一。通过牙测量分析发现,不同人群的性二态性存在差异,因此有必要获取特定人群的数据,以助力实现身份识别。本研究旨在利用牙测量分析确定奥里萨邦人群的性二态性。
本研究共纳入200名年龄在18至25岁之间的受试者(100名男性和100名女性)。使用数字游标卡尺测量除第三磨牙外的28颗牙齿(上颌和下颌)的口腔内近远中(MD)和颊舌(BL)尺寸。数据进行图表记录和解密,并使用SPSS软件20版进行统计分析。
我们的研究表明,与女性相比,男性的牙齿尺寸更大(上颌左右中切牙、第一和第二磨牙)。有趣的是,在少数牙齿中也观察到了反向二态性。
本研究结果表明,牙齿的线性(MD和BL)尺寸在个体性别鉴定中起主要作用。这些差异或反向二态性可能是地理差异的结果。
