In the present investigation, the height of an arch andincisor-incisor and inter-canine distance of the north Indian population were studied odontometrically as a basis for the determination of sex. Amongst all teeth, the mandibular canines are found to exhibit greatest sexual dimorphism. The present study was conducted on 80 subjects (male:female 40:40) in the age group 18–26 years (as the attrition rate is minimum), in order to establish the significance of morphometric measurements of the parameters (from self inflicted bites on skin) as a criterion for sex estimation. The study quantifies the existence of a statistically highly significant sexual dimorphism in morphometric measurements for inter-canine distance (maxillary p < 0.006, mandibular p < 0.0004) as compared to incisor-incisor distance (maxillary p < 0.037, mandibular p < 0.035) and insignificant for height of an arch (p < 0.9).These studies indicate that morphometrically intercanine distance can be a useful parameter for estimation of the sex as compared to the other parameters. This study can be used as a basis for sex estimation from dismembered bodies.
