Abstract: The aim of the present study is to analyse differences in the palatal rugae patterns and maxillary arch length of adult male and female patients. To study the individuality of palatal rugae pattern like shape, direction and unification among the study population and to compare the rugae pattern among the males and females and its usefulness in gender determination. The study group comprised of 500 subjects which included 250 males and 250 females in the age group of 20-35 years from the Department of Oral Medicine & Radiology of the Vananchal dental college & hospital, Garhwa, Jharkhand. All individuals selected for the study comprises of the same geographical population i.e resident of Jharkhand, healthy, free of any diagnosed congenital abnormalities, inflammation, trauma or orthodontic treatment. After the institutional ethical committee clearance & a written consent from patient, a detailed history of all the patients were recorded and maxillary alginate impression was made. The use of palatal rugae in forensic identification is advantageous because of their low utilization cost, simplicity and reliability. Palatal rugae have been shown to be highly individualistic and have consistency in shape throughout the life and can be used successfully for human identification. Palatal rugae play an important role in medico legal identification. In addition, the rugae pattern appears to be specific to the racial groups facilitating population identification. Based on our study, it is sufficiently a characteristic to discriminate between individuals because no two palates are alike in their rugae configuration. Hence, palatal rugae can be one of the tools for personal identification in forensic odontological identification in the Indian context. In view of these findings, palatal rugae could be used as a personal print for identification. This study has indeed demonstrated a clear evidence of the individualistic nature of palatal rugae as have been reported by several authors. This is the study done by using discriminant analysis on arch length and rugae pattern combination. In this study, rugae pattern and arch length on discrimination analysis yielded moderate discriminatory ability between gender and when combination was used discriminatory ability was increased. Hence, the palatal rugae pattern and maxillary arch length can be used as an additional method in differentiating gender between human population groups.
