Background: In forensics, sex estimation is an important step in identification process which can be seen from gonial angle. The purpose of this study was to identify sexual dimorphism in gonial angle based on the difference of external factors such as diet and environment in children, and to assess their capacity as a sex estimator. Study design: The present study consists of 104 subjects (51 males and 53 females) between 7 to 12 years of age which were divided into 2 groups, with prolonged sun exposure-hard diet (Group A) and low sun exposure-soft diet (Group B). The measurements were made using goniometer directly to the subjects.
Results: The mean gonial angle in females is higher than in males and shows significant difference. However, there is no significant difference between Group A and B. Obtained logistic regression achieves an overall accuracy of 68% with cutoff value of 0.46, where the discriminative ability values are not higher than 0.80.
Conclusions: Although there is a significant difference in sex, external factor such as sunlight exposure does not influence in gonial angle. Current results indicate that using mean gonial angle as sex estimation parameter is not advised for children aged 7-12 years.
