Odontometric Evaluation of Maxillary Dentition in South Indian Population for The Assessment of Sexual Dimorphism-A Descriptive Cross-Sectional Study

Introduction: The gender identification from human remains is an imperative and significant area pertained to forensics. Tooth odontometry plays a decisive role in sexual dimorphism. Tooth being the hardest and chemically stable structure of the hu-man body are resistant to various destructive effects caused by trauma and incineration while the other skeletal parameters are more inclined to such effects. Maxilla being a direct part of skull bone, maxillary tooth odontometry plays a pivotal role in sex assessment.Aim: Odontometric analysis maxillary anterior and posterior teeth to analyse which teeth odontometric measurement is best for the gender assessment from maxillary cast.Materials and Method: The study group comprised 80 maxillary casts (40 male and 40 female subjects respectively) of dental stone. Digital vernier caliper was used to measure tooth dimensions. These measurements were then subjected to statistical analyses including descriptive analysis (mean), independent t-test (sexual dimorphism), using SPSS software version 11 [p value <0.05].Result: It was observed that when the average teeth Odontometric index of male and female maxillary casts were statistically analysed (independent t-test), a statistically significant result was obtained (p value <0.05) with increased value in Odontomet-ric measurement for males compared to females.Conclusion: The results observed in this study led us to conclude that the variations in the dimensions of maxillary canine index, maxillary central incisors and maxillary molar among male and female population can be used as reliable tool of sexual dimorphism and gender determination in forensic analysis.
