Most people agree that a person’s palatal rugae pattern doesn’t change throughout the course of their lifetime, and this is known as palatal rugoscopy. The rugae pattern can survive when most other anatomical components are burned or destroyed because of their interior placement in the cranium. Because rugae patterns are believed to be as distinctive as fingerprints, they are also utilised for personal recognition. This study’s objective was to distinguish and contrast the palatal rugae of North Indians and Negroids in terms of quantity, size, and morphology. There are two categories in the study: North Indians and Negroids. The sample consists of 40 plaster casts, evenly split between two groups and genders, with ages ranging from 18 to 25. Method To identify the rugae on the cast and classify them according to Kapali et al. (1983) and Thomas and Kotze (1983), a sharp graphite pencil, adequate illumination, and magnification were required. Result The overall count of rugae in the Nigerian and North Indian communities to the right and left of MPR ranged from three to twelve, according to the quantitative study. North Indian males and females had a maximum of 10 rugae, while Nigerian males and females had a maximum of 12 rugae. In North Indian males and females, the lowest rugae count was 10, and it was found in three. In Nigerian male and female the least count of rugae was 5 and it was present in 2. Conclusion Given the limits of the current study, another way to differentiate between North Indian and Negroid is through the rugae pattern.
