CORRELATION OF LIP PRINT, RUGAE PATTERN AND ABO BLOOD GROUP AMONG DENTAL STUDENTS FROM HARYANA: A FORENSIC STUDY

Abstract

Introduction: Lip prints and palatal rugae are highly individualistic and stable structure, resist changes to disease and trauma and stays permanent throughout life. Correlation of lip print, rugae pattern and blood group can contribute to more precise personal identication apart from other conventional methods. Aim: To correlate lip prints and rugae pattern to blood group among dental students from Haryana. Methodology: Total 100 dental students were included in the study and divided into two groups of 50 males and 50 females. Lip prints were recorded using lipstick and cellophane tape, analyzed according to Suzuki and Tsuchiashi's classication. Rugae pattern were recorded using alginate and analyzed on the cast according to Kapali et al classication. Blood group of the same individuals were recorded and correlated. Obtained data was statistically analyzed using SPSS software v 21.0, IBM. Results: Statistically non-signicant difference was found between both male and female in upper lip pattern (p= 0.751) whereas for lower lip statistically signicant difference was found in males (p=0.004) with predominance of type III pattern whereas in females type I, II patterns predominated. For rugae, statistically non-signicant difference was found (p=0.196), in both the groups with predominance of wavy pattern and no difference in the frequencies of each type of blood group in both genders were seen. Conclusion: Rugae pattern was found to be signicantly correlated with blood group, with higher frequency of wavy pattern among dental students from Haryana
