Crime Solvers: A Correlative Study Amongst 500 Individuals

Abstract

Context: Human blood group, lip prints, and fingerprints are unique to an individual. Literature reveals very few studies correlating all three parameters simultaneously, emphasizing the need of further studies with different parameters taken together to increase the success rate of such identification methods. Aims and Objectives: To determine the correlation among lip prints, fingerprints, and blood groups and their importance in forensic dentistry. Materials and Methods: Study group included 500 patients and their lip prints, fingerprints, and blood groups were analyzed and recorded. Statistical analysis was performed using SPSS version 18.0; IBM, Armonk, New York, USA. Chi-square test was used to find the significance of study parameters on categorical scale between two or more than two groups. Results: Correlating all three parameters together we found in males maximum incidence of individuals in loop type fingerprint with intersecting type lip pattern in B-positive blood group individuals (n = 25, 10%), and the results were statistically significant (P < 0.001). In females, maximum incidence of individuals was seen in loop type fingerprint with full-length type lip pattern in O-positive blood group individuals (n = 43, 17.2%); however, the results were statistically nonsignificant (P = 0.027). Conclusion: Considering these parameters together may help to obtain more accurate results and increase the reliability of assessment.
