性别鉴定是从人类遗骸确定个人身份的核心。这项研究的目的是为了了解通过牙齿测量方法确定性别的准确性。探讨恒牙列所有牙齿的近远中径和颊舌径，以寻找区分男女牙齿的新参数，并评估每种线性测量方法是否可独立用于牙列性别鉴别。这项研究是在一所牙科学院进行的，共有500人，其中男性250人，女性250人。用藻酸盐印模材料制作上下颌印模，用牙石制作铸型。使用游标卡尺测量除第三磨牙外的所有上颌牙齿的BL和MD尺寸。结果进行统计分析，采用单因素分析和线性逐步判别函数分析，找出变量的性别区分显着。男、女MD和BL维度差异有统计学意义。性别正确分类的预测值也有统计学意义。发现使用逐步判别函数区分人群性别的能力非常高，准确率为99.8%，男性的牙齿在统计学上大于女性。这与使用骨盆和头骨进行性别确定的近100%成功率相似。
Gender determination is central in establishing personal identification from human skeletal remains. The study was conducted to find out the accuracy with which gender can be determined by odontometric methods. To investigate the mesiodistal (MD) and buccolingual (BL) dimensions of all the teeth of permanent dentition to find new parameters to differentiate between male and female teeth and to assess whether each type of linear measurement can be used independently in odontometric sex differentiation. The study was conducted at a dental college on a composite group of 500 individuals comprising 250 males and 250 females. Impressions of upper and lower jaws were made with alginate impression material and casts prepared with dental stone. A digital Vernier calliper was used to measure the BL and MD dimensions of all the upper teeth except the third molars. The results were subjected to statistical analysis using univariate analysis and linear stepwise discriminant function analysis to find the variables which discriminate gender significantly. The MD and BL dimensions between males and females were statistically significant. The predicted value for correct classification of gender was also statistically significant. The ability to differentiate gender in the population using stepwise discriminant functions was found to be very high with 99.8% accuracy with males showing statistically larger teeth than females. This is similar to the near 100% success in gender determination using pelvic and skull bones.
