Evaluation of the mesiodistal dimensions of the maxillary anterior teeth and its role in gender determination: An observational study

Abstract

Aim: To Study on Gender Determination Using Mesiodistal Dimensions of Anterior Teeth. Methods: A prospective observational study was conducted in the Department of Orthodontics and Dentofacial Orthopaedics, Rajasthan Dental College and Hospital, Jaipur, Rajasthan, India for the period of one year. This study includes a total of 70 randomly selected study volunteers. The patients ranged in age from 20 to 30 years old, with no history or clinical signs of crown repair, orthodontic therapy, or trauma. Following informed permission, the mesiodistal dimensions of maxillary front teeth were measured between anatomical contact sites using a vernier calliper held parallel to the occlusal plane. Results: The study's findings revealed that teeth 13 and 23 had sexual dimorphism, but teeth 11-22 had no statistically significant sexual dimorphism. When the degree of accuracy for sex determination was evaluated using 13 distinct males and females, it was discovered that 45 percent of females were accurately categorised and 55 percent of males were correctly classified. When the degree of accuracy for sex determination was evaluated using 23 distinct males and females, it was discovered that 62 percent of females and 62 percent of males were properly categorised. Conclusion: The study found that maxillary canines had considerable sexual dimorphism and can be utilised for sex determination in conjunction with other techniques.
