Abstract

Context Use of teeth has achieved lots of prominence in post mortem identification, however in edentulous and badly decomposed bodies palatine rugae can be used as an important alternative. Palatal rugae are considered very unique and have been equated to fingerprints. The aim of the present study was to identify and compare the morphology of rugal pattern in males and females of Gulbarga population, India and to determine the morphological difference in the palatal rugae in different age groups.
Settings and Design A descriptive cross sectional study with a sample of 160 adults visiting the OPD of Al-Badar Rural Dental College and Hospital were included.
Methods and Material A sample of 80 adult males and 80 females, age group 20–40 years were included. Impressions of maxillary arch were made with alginate and Thomas et al. (1983) method of rugae identification was used.
Statistical Analysis Used All the data was analyzed for number, shape, length of the palatal rugae and difference in the gender was sought using two sample t-test and
Chi-Square tests.
Results Statistically significant difference was found in unification, converging type being predominantly present in females and diverging unification in males. Circular type of rugae was predominant in females, whereas wavy was slightly more common in males and straight more common in females.
Conclusions No significant difference was seen in total number of rugae in genders. Other parameters showed significant differences in forms of rugae. Therefore, it may be concluded that the rugae pattern may serve as an important tool for human identification.
