未成熟骨骼的性别鉴定一直是法医人类学中亟待解决的难题。在这种情况下，牙齿的牙齿测量功能可能会有很大的帮助。牙齿是人体中最坚硬、化学成分最稳定的组织，是人类学、遗传学、牙科和法医学研究中生物和非生物种群的极佳材料。使用牙齿大小标准，只要有可能预测性别，身份识别就会变得更容易，因为这样只需要考虑一种性别的失踪人员。根据上颌尖牙指数和上颌第一磨牙大小从牙科测量数据判断性别，并确定哪一项指数在仅使用上颌石膏进行性别判断时准确率较高。对200人(男100人，女100人)的上颌牙弓取藻酸盐印模，浇注牙石。用游标卡尺测量模型上上颌第一磨牙(颊舌侧和近远中侧)的大小、尖牙和尖牙间的距离。对所得数据进行判别统计分析。本研究得出结论：上颌第一磨牙的BL尺寸比其他磨牙尺寸和尖牙尺寸是更可靠的性别判定指标。
Sexual identification of immature skeletal remains is still a difficult problem to solve in forensic anthropology. In such situations, the odontometric features of the teeth can be of immense help. Teeth, being the hardest and chemically the most stable tissue in the body, are an excellent material in living and nonliving populations for anthropological, genetic, odontologic, and forensic investigations. Using tooth size standards, whenever it is possible to predict the sex, identification is made easier because then only missing persons of one sex need to be considered. To determine sex from the odontometric data using maxillary canine index and maxillary first molar dimensions and to determine which index gives higher accuracy rate for sex determination using only maxillary cast. In a sample size of 200 population (100 male and 100 female), alginate impression was taken of maxillary arch and poured with dental stone. Using Vernier caliper, the dimension of maxillary first molar (buccolingual [BL] and mesiodistal [MD]), canine (MD), and intercanine distance was measured on the cast. The obtained data were analyzed using discriminant statistical analysis. This study concludes that BL dimension of maxillary first molar is a more reliable indicator for gender determination than other molar and canine dimensions in maxilla.
