Comparative Analysis of Lip prints, Finger prints and Blood Groups: A Cross-sectional Study.

In forensic identification the mouth allows for a myriad of possibilities. Due to distinctive features, dental identification plays a key role to positively identify an individual.Sulci laborium present on the labial mucosa forms a characteristic pattern known as lip prints. Lip prints are important because of their uniqueness.Blood group classification is based on the presence or absence of antigens on the surface of the RBCs. OBJECTIVES: To study and correlatethe various types of lip prints,finger prints and blood groups. METHODOLOGY : In this study, lip prints finger prints and blood group were obtained from 200 individuals. The central part of the lip was analysed based on the classification given by Suzuki and Tsuchihashi.Thumb printanalysis was done by Michael and Kucken classification which classifies it into arch, whorl and loop type, blood group was analysed by Landsteiner’s classification. RESULTS : Type IV (reticular) lip pattern was predominant lip print pattern, loop type was predominant finger print pattern andB+ve blood group was commonly found. Type IV lip pattern and loop finger print correlation, Type IV lip print and B+ve blood group correlation andA+ve blood group and loop finger print correlationwere predominantly found to be significant. CONCLUSION : Correlation of three parameters was not significant but each individually played a vital role in identification.
