AbstractAims: The purpose of this study was to investigate whether sexual dimorphism can be established by odontometric study of permanent mandibular canine teeth as well as canine arch width. Methods: This study was carried out on 40 subjects of subjects selected from Sardar Patel dental and medical sciences, Lucknow. Out of these 40 subjects, 20 subjects were female and 20 subjects were male. Both sexes belong to age group between 17 to 25 years. The following measurements of the permanent mandibular canine teeth were taken: mesio-distal width of the crown and intercanine distance. From these measurements mandibular canine index was calculated. In addition, the percentage of sexual dimorphism was calculated. Results: There was sexual dimorphism in mesio-distal width, canine arch width and canine index of permanent mandibular canine teeth. Sexual dimorphism is more on right permanent mandibular canine teeth than left permanent mandibular canine teeth. Conclusion: According to the present study, sexual dimorphism in mesio-distal diameter is more in right mandibular canine is than left mandibular canine teeth. Sexual dimorphism in canine index is more in right mandibular canine (3.94%) is than left mandibular canine teeth (1.92%).
