The odontometric analysis parameter helps in stimulation of a dental impression in both gender, male and female, study of the sexual dimorphism using the odontometric measures or metric system and study the class and specific characteristics for individual identification. The present study is conducted to find out and evaluate the relationship between the inter-canine distance of mandibular permanent canine in gender identification. The second objective was to investigate whether there exists any correlation between odontometric measures and sexual determination in bite marks.

To evaluate and find the relationship between the intercanine distance of mandibular permanent canine in gender identification.

The study comprised of 50 subjects of age between 17 to 40 years consisting of 28 male patients and 22 female patients, selected from the outpatient departments of a tertiary dental care hospital in Chennai between September 2018 and January 2019. Subjects are asked to bite the modelling wax to record the bite mark and fine tipped pen are used to mark the parameter. The intercanine distance of mandibular permanent canine are measured by using a Vernier caliper. Percentage and statistical values from the segregated data will be presented in the table and graph.

The mean value for males is 27.3214mm and for females is 25.1818mm. Females have lower mean value of intercanine distance of mandibular permanent canine compared to males. There is significant differences between these two mean values. The standard deviation for both males and females are 0.045171 and 0.000137.

With highly significant values obtained, the mandibular inter-canine distance parameter can serve as important aid in gender identification specifically in forensic odontology and medico-legal issues investigation.
