Palatine rugae can be used as an alternative source of forensic information to identify a person because none of the rugae pat-terns are the same even in twins. The study was conducted to determine the comparison of the shape and size of palatine rugae based on gender in dental students batch of 2022 and 2023 Baiturrahmah University. With a cross-sectional design, a popula-tion of 67 samples was obtained with random sampling technique. Univariate analysis is presented in the form of frequency dis-tribution and percentage, bivariate analysis using chi-square test, and data processing using computerised SPSS program IBM version 25.0. Of the 6 forms of palatine rugae based on the Thomas and Kotze classification, it was found that in the male gender the most was straight, namely 17 people (50%), and in women the most was wavy, 14 people (42.4%).
