Evaluation of Sexual Dimorphism in Maxillary Right First and Second Molars and Mandibular Left Canine in Syrians

Introduction: Sex determination is an important step in establishing the biological profile of unidentified human remains in forensic science. Tooth size variations have been reported among sexes and different populations. Aim: The aim of this study is to assess the sex of unknown skeletonized or decomposed human remains in Syria using metrical measurements on teeth. Materials and Methods: The sample involved 266 individuals from Syrian population (137 female,129 male) aged 18-22 years. mesiodistal widths of left mandibular canines, Buccolingual and mesiodistal widths of first and second upper right molars were measured on gypsum casts with help of digital vernier caliper. These parameters were subjected to different analysis using SPSS 20.0 software. Kolmogorov-Smirnov test showed that data were normally distributed, then the parameters were analyzed by t-test for independent samples. And LRA for predicting accuracy percentage. Results: All detected parameters in this study showed significant statistical gender difference, mesiodistal width of mandibular canines measurements showed the highest difference, with (P < 0.001 _ mean: 7.139 ± 0.49 mm for males, 6.519 ± 0.28 mm for females). Conclusion: The findings support the usefulness of employing odontometric analysis of the canines and first and second upper right molars in gender estimation that lead to identification of unknown person in Syrian population.
