We investigate the accuracy of odontometric methods in sex determination, using a sample from the Portuguese population. Measurements were made on dental casts using a digital caliper, and various odontometric indexes have been defined using upper incisor and canine teeth. Comparison of the means in both sexes was performed using Student's t-test. Significant differences (p<0.05) were found in all variables except for the "Incisor Index". The canine showed the greatest sexual discriminant characteristics. In the presence of one or both canines the distobuccal-mesiolingual crown diameter and the "Robustness Value" allowed discrimination between sexes in the studied population. We also provide further arguments on the debate on whether sex determination is population specific.
我们使用来自葡萄牙人群的样本，研究牙测量方法在性别判定中的准确性。使用数字卡尺对牙模进行测量，并使用上颌切牙和尖牙定义了各种牙测量指标。采用学生t检验对两性的均值进行比较。除“切牙指数”外，所有变量均存在显著差异（p<0.05）。尖牙表现出最大的性别判别特征。在存在一颗或两颗尖牙的情况下，远中颊侧-近中舌侧牙冠直径和“粗壮值”能够在研究人群中区分性别。我们还为关于性别判定是否具有人群特异性的争论提供了进一步的论据。
