Key points
- Sex determination was achieved by analyzing metric measurements of all 32 tooth crowns.
- Measurements included crown length, mesiodistal width, and buccolingual width.
- SPSS and MATLAB software were used for data analysis and discriminant calculation.
- The method offers an easy and objective way to determine sex, even with limited teeth.

Abstract
Teeth that are resistant to external stimuli and have little diversity for individuals can be an important identification factor. This study aimed to present a method that can be used easily and accurately to identify individuals using their teeth, specifically to determine their sex. In this study, all teeth were extracted from 166 cadavers and, from these teeth, the crown length, mesiodistal width, and buccolingual width were measured using a digital caliper. The measurements were then analyzed using SPSS and MATLAB software. First, tooth crown morphology was compared between males and females. Regression analysis was performed for each measurement separately for both males and females. Finally, each linear discriminant was calculated from the measurements of all tooth crowns to confirm accuracy. Since teeth began to be used for individual identification, most methods required various types of teeth and measurements for sex determination, even if high accuracy was presented. Considering these limitations, sex determinants were derived from all teeth, suggesting that an easy and objective way could be derived to determine sex, even in a limited situation where all teeth could not be used.
