Introduction: Well protected palatal rugae patterning in the oral cavity has been suggested as useful complimentary information for forensic purposes. Also since the blood group remains same throughout the lifespan of an individual, can act as a biological record.

Aim: The aim of the presentation is to study the different palatal rugae patterns and to correlate and compare palatoscopy with blood group among patients visiting Indira Gandhi government dental college Jammu.

Materials and methods: A total of 100 patients with age group ranging between 14-45 years with known blood group were included in the study. Palatal rugae patterns on plastercasts, were obtained and examined for different biometric characteristics including number, shape, length and association with sex and the data was obtained.

Results: There was significant association found between palatal rugae, ABO blood groups and Rh factor (chi square statistic=18.205, P=0.034).

Conclusion: The study concluded that palatal rugae when correlated with suspect’s specific blood group-Rh factor can be used to narrow down the suspect list and can also prove significant in identifying individuals in case of any disaster.
