Sex assessment from tooth measurements can be of major importance for forensic and bioarchaeological investigations, especially when only teeth or jaws are available. The purpose of this study is to assess the reliability and applicability of establishing sex identity in a sample of Greek population using the discriminant function proposed by Rösing et al. (1995). The study comprised of 172 dental casts derived from two private orthodontic clinics in Athens. The individuals were randomly selected and all had clear medical history. The mesiodistal crown diameters of all the teeth were measured apart from those of the 3rd molars. The values quoted for the sample to which the discriminant function was first applied were similar to those obtained for the Greek sample. The results of the preliminary statistical analysis did not support the use of the specific discriminant function for a reliable determination of sex by means of the mesiodistal diameter of the teeth. However, there was considerable variation between different populations and this might explain the reason for lack of discriminating power of the specific function in the Greek population. In order to investigate whether a better discriminant function could be obtained using the Greek data, separate discriminant function analysis was performed on the same teeth and a different equation emerged without, however, any real improvement in the classification process, with an overall correct classification of 72%. The results showed that there were a considerably higher percentage of females correctly classified than males. The results lead to the conclusion that the use of the mesiodistal diameter of teeth is not as a reliable method as one would have expected for determining sex of human remains from a forensic context. Therefore, this method could be used only in combination with other identification approaches.
通过牙齿测量进行性别评估对于法医和生物考古学调查可能至关重要，尤其是在仅能获取牙齿或颌骨的情况下。本研究的目的是评估使用罗辛等人（1995年）提出的判别函数在希腊人群样本中确定性别身份的可靠性和适用性。该研究包括从雅典的两家私人正畸诊所获取的172个牙模。这些个体是随机选取的，且都有清晰的病史。除了第三磨牙外，测量了所有牙齿的近远中牙冠直径。首次应用判别函数的样本所引用的值与希腊样本获得的值相似。初步统计分析的结果不支持使用该特定判别函数通过牙齿近远中直径可靠地确定性别。然而，不同人群之间存在相当大的差异，这可能解释了该特定函数在希腊人群中缺乏判别力的原因。为了研究使用希腊数据是否能获得更好的判别函数，对相同的牙齿进行了单独的判别函数分析，得出了一个不同的方程，然而，在分类过程中并没有任何实际的改进，总体正确分类率为72%。结果表明，正确分类的女性比例明显高于男性。结果得出结论，在法医背景下，使用牙齿近远中直径作为确定人类遗骸性别的方法并不像预期的那样可靠。因此，该方法只能与其他识别方法结合使用。
