Background The most crucial evidence that is left behind at the crime scenarios that might narrow down the suspect pool are lip prints and fingerprints. These are undoubtedly the most reliable and valuable evidence till date in the court of law. One more biological record that remains unchanged throughout the lifespan of a person is the blood group. Aim and Objectives To study, correlate and compare cheiloscopy and dactyloscopy with blood group among dental students in the Western Maharashtra population. Materials and Methods A total of 200 dental students with age groups ranging between 18-25 years were included in the study. Lip print pattern, fingerprint pattern and ABO blood groups were collected and compared. SPSS version 20.0 was used to analyse the data. Results There was a statistically significant correlation between lip prints and ABO - Rh (χ2 37.56, P < 0.05) as well as between fingerprints and ABO-Rh blood groups (χ2 30.6, P < 0.05). Conclusion Hence, this study concluded that fingerprints-ABO blood group and lip prints-ABO blood groups are valuable evidence that can be relied upon in forensic investigations for the identification of the suspect in crime.
