Objective:
Evaluation of sexual dimorphism is a crucial concern for anthropologists, forensic scientists, and archaeologists. Teeth have been used as an alternative tool to determine sex in forensic anthropology. However, it is necessary to use data specific to a particular population, as different populations exhibit varying degrees of sexual dimorphism. This study aimed to determine the sexual dimorphism in the buccolingual dimensions of permanent anterior teeth in the young Iranian population.
Materials and methods:
A total of 100 students (50 females and 50 males) participated in the current study. A total of 1200 permanent anterior teeth were examined. The buccolingual dimension of all anterior teeth was measured using Vernier Calipers with a calibration of 0.01 mm. Data were analyzed using an independent sample T-test and paired sample T-test, and a P-value of less than 0.05 was considered statistically significant.
Results:
The mean values of the buccolingual dimension of the maxillary canines on the right and left sides (13, 23) were statistically greater in males than females (P=0.04, P=0.03) and had the greatest percentage of sexual dimorphism (4.08% and 5.26%, respectively).
Conclusion:
The buccolingual dimension of Iranian canines could be used as a reliable material to identify gender in forensic studies, and the degree of sexual dimorphism varies among different populations. Therefore, it is essential to use the relevant data samples for each population. It was concluded that Europeans had the greatest amount of sexual differences in the anterior teeth, while Iranians had the least amount of sexual dimorphism in the anterior teeth.
