Background: All humans have an identity in life; compassionate societies require this identity to be recognized even after death. Objectives: To measure the dimensions of the mandibular canine and assess the usefulness of the mandibular canine as an aid in gender estimation.Materials and Methods: The study population comprised 200 subjects inclusive of 100 males and 100 females with an age range of 18–25 years. Measurements made in mm at the contact point were of mesiodistal width of the right and left canines and intercanine distance both intraorally and on casts, and the mandibular canine index (MCI) was calculated. The obtained data were subjected to t-test/Mann-Whitney test and discriminant function analysis. Results: All parameters of mandibular canines, namely, intercanine distance, canine width, and canine index were greater in males compared to females suggesting significant sexual dimorphism of mandibular canines. On subjecting the data to discriminant function analysis, it classified sex correctly in 73% of the samples. Conclusion: The result of our study establishes the existence of significant sexual dimorphism in mandibular canines. We can therefore, recommend the use of mandibular canine dimensions as an applicable and additional method for gender determination in human identification.
