Dental Sexual Dimorphism

Abstract

Abstract Objective : Forensic odontology is a lineage that deals in relation to jaws and teeth as evidence to law and justice. Tooth serves as a prime importance in the context of sex identification. (1) To investigate whether there exists any correlation between odontometric measures and sexual dimorphism. (2) To compare the inter-canine arch width of mandible. (3) To evaluate the mean value of standard mandibular canine index. Method: This study is an odontometric analysis performed intra-orally with a sample of 150 teeth (75male:75 female) on students of Kanti Devi Dental college, Mathura. Mesiodistal dimensions of mandibular right and left canine with a caliper device and statistical analysis for significance of sexual dimorphism was done with student’s t test. Result: The result showed that sexual dimorphism is significant in relation to mesiodistal diameter of canine. Furthermore, there was statistical significant difference in tooth crown dimension between males and females where the males showed higher mean values. Conclusion: The study show definite statistically significant sexual dimorphism hence they can play significant role in providing expertise in civil & criminal proceedings to ensure that forensic dentistry will remain viable component of forensic medicine.
