Aim: The aim was to determine the gender differences in rugae pattern with regards to the length, number, and shape. Materials and Methods: Fifty patients (25 males, 25 females) aged 30-50 years were randomly selected from the routine outpatient department at Sinhgad Dental College and Hospital. Maxillary impressions were made using alginate hydrocolloid and cast in dental stone. Palatal rugae pattern were then evaluated under the parameters such as length, number, and shape. Results: The association of rugae pattern (length, number, shape) and the gender was analyzed using Chi-square test for qualitative variable and t-test for quantitative variable. The average length of the rugae was greater in males than in females. The average numbers of rugae were same in both males and females. Straight pattern was commonly seen in females than in males. Analysis showed significant difference with parameters like length and shape (straight pattern) in both the males and females. Conclusion: As the analysis showed significant difference with the length and shape of rugae patterns in both males and females, rugoscopy, thereby could be an important tool for gender identification. The study will be continued with larger sample size to expand knowledge about gender differences in palatal rugae patterns.
