Introduction: Teeth are an excellent material in living and non living populations for anthropological, genetic, odontologic and forensic investigations. "Sexual Dimorphism" refers to those difference in size, stature and appearance between male and female that can be applied to dental identification. Canines are the most stable teeth in the dental arches. Aim of this to study the impacts of 'sex factors" on the morphometry of human canines. Material and methods: 180 subjects, 90 males and 90 females in the age group of 17-23 years were selected for this study. The study was conducted on the undergraduate students of 1st year of Gajra Raja Medical College, Gwalior. The measurements of the mesiodistal width of teeth were taken by using a sliding Vernier caliper. The intercanine distance was measured between the tips of the mandibular canines and then between the tips of the maxillary canines, intraorally. Results: A highly significant sexual dimorphism can found in the human permanent canines in their mesiodistal crown diameters in the present study. The right mandibular canine was found to be most sexual dimorphic as all the canines followed by right maxillary canine, left mandibular canine and left maxillary canine. Conclusion: It was concluded that the mesiodistal width of all four canines are significantly different in male and female as are the mandibular maxillary canines indices. The mandibular intercanine distance was not significantly different. The mean value for mesiodistal crown diameters were established.
