Background: Palatal rugae's uniqueness, its resistance to heat, and stability throughout life have been proved by its use as an alternative aid in individual identification where comparison of fingerprints and other records. Palatal rugoscopy, or palatoscopy, is the process by which human identification can be obtained by inspecting the transverse palatal rugae inside the mouth. The rugae patterns are unaffected by physical and chemical injuries and hence can serve us reliable tool in sex determination and forensic identification process. Hence this study was conducted to use palatal rugae as an effectivemode for sex differentiation. Materials and Methods: 50 patients attending outpatient department in a dental college were selected based on convenience sampling technique, out of which 25 were males and 25 were females. Maxillary alginate impression was taken and the obtained maxillary cast was visualised to identify the palatal rugae pattern according to Thomas and Kotze classification. Data was subjected to statistical analysis. Results: A total of 756 rugae were found in the 50 individuals. Out of these, 401 (53.04%) were found in males and 355 (46.96%) in females. Hence, number of rugae and type of rugae( wavy, curvy, straight) were more in males compared to females. Conclusion: The uniqueness and overall stability of palatal rugae suggests their use as a viable alternative for forensic identification in different groups. Researches have to be conducted in larger sample sizes, encompassing various geographical areas, for better statistically significant results, for which records are a necessity.
