Abstract

Background: This research paper aims to investigate the effectiveness of gender identification utilizing palatal rugae.

Materials and methods: The size of the sample that was selected included 100 people. They were made up of 50 men and 50 women, all in between the ages of 18 and 25. To examine their palatal rugae patterns, casts were made after taking maxillary impressions. Based on the size and rugae amount found on the left as well as the right sides, the palatal rugae patterns were investigated. Rugae patterns have been recognized based on the categorization provided by Thomas and Kotze (1983).

Statistical analysis: Chi-square analysis has been used.

Results: There were comparative variations in the shape of rugae patterns among male and female individuals. The study revealed that the circular pattern was higher in males (P < 0.01) as compared to females and the unification pattern was comparatively greater in females (P < 0.05) as compared to males. The most predominant pattern that was seen in both genders was the wavy pattern that was seen to be present in 57.17% of males and 53.42% of females. The rugae number on the right and left sides did not exhibit any significant variations.

Conclusions: This research thus exhibits a relevant difference in patterns of rugae and also confirms the uniqueness of patterns in each individual. Hence, it could be utilized as an adjunct to other tools for identification in the forensic sciences.
