- Abstract
Background: "Sexual dimorphism" is an organized variance in shape and structure among males and females belonging to the same species. Permanent teeth have been extensively studied for this purpose but little light has been shed on the significance of sexual dimorphism with regards to primary teeth. The extent and pattern of "sexual dimorphism" are unique and differ from one population to another. Hence, there is also a need to assess these variations among different ethnic groups. Objective: To determine sexual dimorphism using odontomorphometric and facial anthropometric traits in the ethnic Tamil pediatric population. Materials and methods: The study was conducted among a sample of 100 pediatric patients aged between 2 and 6 years. A digital vernier caliper was utilized to measure the mesiodistal width of all the deciduous teeth. Facial anthropometric measurements of bitemporal width, bizygomatic width, and bigonial width were also measured using the digital vernier caliper. Result: Significant sexual dimorphism was seen in relation to maxillary and mandibular right canine, first molar, and mandibular right central incisor (p < 0.05). Significance was also seen in the facial measurements, the intertemporal, interzygomatic, and intergonial width (p < 0.05). However, using Pearson's correlation a negative correlation was seen between odontometric and anthropometric traits. Conclusion: Analysis of significant traits in a specific population has significant impacts on forensic applications like gender determination and identification. However, the study has to be carried out on a larger sample size for further validation.
