Efficacy of the canine mandibular index technique with permanent dentition to estimate sex in humans. (2021). World Health Journal, 2(1), 26-30.


Objective: To determine the efficacy of the Mandibular Canine Index technique with permanent dentition to estimate sex in humans. Methodology: Descriptive, non-experimental cross-sectional study, where 200 plaster models of men and women were evaluated. Intercanine distances and mesiodistal diameters of the left and right canines were obtained using a digital vernier caliper with a resolution of 0.01mm. The sexual dimorphism of the right canine and the left canine was then determined. After that, the ICM averages were determined. Results: The ICM with permanent dentition obtained an efficiency of 69% to estimate the male sex and 67% of the female sex. Conclusions: The Mandibular Canine Index (CMI) technique with permanent dentition is effective for estimating sex in humans.
