A Study of Cheiloscopic Pattern in Relation to Gender and Blood Groups in a Tertiary Care Hospital at Chennai

Abstract

Personal identification is of vital importance in forensic odontology for ethical, humanitarian and criminal enquiries. The applicability of Cheiloscopy ( study of pattern of lip print), one of the easiest tools available in individual and medicolegal identification, is an area of extensive research in recent years. With the objective to investigate the uniqueness of lip patterns in relation to gender and blood groups, this study was conducted on 100 subjects, which included 50 males and 50 females. The lip prints obtained were studied by applying Suzuki and Tsuchihashi's classification.Type 2 (37%) was the most common lip print type in males and Type 3 (38.5%) was the most common lip print type in females. The Lower lip print can help in gender determination. No significant statistical correlation was found between the lip print patterns and blood group. Along with the traditional methods of identification like fingerprint analysis,Cheiloscopy can also be helpful in the identification of a person.However, the utility of the same in forensic medicine still remains largely untapped and unacknowledged. Similar studies with larger sample sizes are required to obtain statistically significant reports thereby allowing a more impactful emergence of lip print patterns usage in forensic analysis.
