“Analysis of Lip prints, Finger prints and Blood groups: A comparative study”

Abstract

Background- In forensic dentistry, the oral cavity plays a very important role because of the unique anatomy of the teeth. Although DNA comparisons and finger print analysis are common techniques which are employed to ensure fast and secure identifications, there are certain crime scenarios where other supplemental aids like lip prints, palatal rugae pattern, bite marks, etc becomes indispensable. So the present study involved 3 parameters to analyze the most common patterns of lip print, finger print and blood group in the study population.
Materials and Methods- This study included 150 healthy individuals (75 males and 75 females) from the age group 18-30 years. Lip prints, Finger prints and Blood groups were obtained from all the individuals to analyze the different patterns.
Results- Lip print analysis was done between males and females and showed statistically insignificant results (p=0.776). Finger print examination showed significant results (p<0.001). The comparison between finger print group and lip print group was done (p<0.002) which was statistically significant. Blood group examination showed statistically insignificant results (p=0.094). Comparing finger print and blood group pattern was also statistically insignificant (p=0.207). On comparison of lip print pattern with blood group the results showed statistical insignificance (p=0.596).
Conclusion- In the given study, no significant association was established on finding out a correlation between lip print, finger prints and blood groups. Hence we conclude by giving a message that these individual parameters can be useful in the crime scenes for evidence purpose only.
