Palatal rugae patterns are thought to remain unchanged from the beginning of formation until the death of the individual, and as unique as fingerprints. This study aimed to compare palatal rugae between ethnic Javanese and non-Javanese in Indonesia. The study sample consisted of maxillary casts from 47 Javanese and 53 non-Javanese subjects. The patterns of palatal rugae were recorded based on the Thomas and Kotze classification. In the results, the only variable with indicated significant difference between the sample populations was observed in the lower frequency of circular shape rugae for the non-Javanese group. The value of this frequency as a population-level indicator is reduced by the relative rarity of this rugae shape.
