Crown size and arch width dimension as an indicator in gender determination for a Puducherry population

INTRODUCTION: Tooth morphometry is resistant to postmortem destruction and can be used as an adjunct in skeletal sex and age determination. Therefore, an attempt was made to compare mandibular canine index (MCI) and Pont's index for their level of accuracy in gender determination for a Puducherry population. AIMS AND OBJECTIVES: To evaluate crown size and arch width dimension for the Puducherry population using MCI and Pont's index. To compare the MCI and Pont's index, for the level of accuracy in gender determination and to validate its use as a forensic tool. MATERIALS AND METHODS: One hundred and six participants (53 males and 53 females) in the age group of 18–25 years of the Puducherry population were included in the study. Their MCI and Pont's index were recorded. RESULTS: The data obtained were subjected to paired t-test analysis. It was observed that right MCI was most accurate and molar index was least accurate in sex determination. CONCLUSION: MCI and Pont's index showed significant sexual dimorphism. They can be used as an adjunct to other tools for sex determination and identification of the person for the Puducherry population.
