INTRODUCTION: Establishing one’s identity is necessary for legal as well as humanitarian purpose. Sex determining is considered to be one of the major factors employed to assist for the identification of a person. Individual identification heavily relies on the quality of the dental records in the office.
AIM: The purpose of this study was to assess the usefulness of the Mandibular Canine Index(MCI) as an aid in sexual dimorphism in Kanpur population using mesiodistal with intercanine distance of mandibular canines.
MATERIALS AND METHOD: This was an experimental study involving the preparation of plaster casts of 200 males and females each residing in Kanpur, UP, India. Both the genders were in the age group of 17-30 years. The casts for study were prepared and measurements of mandibular canine along with intercanine distance were taken. The MCI calculations were done using standard equations. Statistical analysis used students’t-test. All values were considered statistically significant for value of p<0.05.
RESULTS: The present study demonstrated that left MCI predictability for males is more whereas in case of females, right MCI predictability is more, with no significant variation in the intercanine distance.
CONCLUSION: It was found out that mandibular canines exhibit maximum sexual dimorphism, hence, they can be considered as the key teeth for one’s identification.
