Palatal rugae are individual features which are important for personal identification. Present study determines the rugae characteristics and their age-related changes in both sexes.
Palatal rugae status (number, length, thickness, shape, direction, unification) of 323 subjects (180 females/143 males) within the age range of 20-79 years were recorded from their dental casts, divided into four sectors on the right and left sides of the palate and statistically analysed.
The results reveal that there were no statistically significant differences for rugae number distribution due to the sex and right/left sides of the palate (p-value> 0.05 for both analysis). The frequencies of rugae with regard to shape, direction and unification characteristics revealed statistically significant differences (p-value< 0.05). When means were compared within age groups; number, length and thickness of rugae showed statistically significant differences in relation with age (p-value< 0.05).
Age can be assessed by examining the palatal rugae, as its number decreases, length shortens, thickness gets thinner by ageing (p-value< 0.05). Therefore, rugae can be accepted as complementary evidence for forensic odontologists especially for age assessment of edentulous cases.
