Introduction: Cheiloscopy is the study of furrows and grooves present on the red part, or the vermilion border of the human lips. The type of grooves is unique to an individual and can be used for person identification.
Aim: The aim of this study is to ascertain whether the uniqueness of lip print (LP) can help in identifying a person. In addition, we aimed to evaluate whether there is any correlation between LP types and blood groups.
Materials and Methods: A cross-sectional study was conducted on 100 participants (51 males and 49 females), aged between 18 and 50 years, to determine any correlation between LP types and blood groups. These lip patterns were analyzed and interpreted using Tsuchihashi’s classification, and later, associated blood group matching was performed to determine the predominant LP type with the ABO and Rh blood grouping system.
Results: The present study showed a positive correlation between LP pattern and blood group among males and females. Thus, the distribution of LP patterns and ABO blood groups might help in the identification of an individual.
Conclusion: Since LP and blood group are unique to a person, cheiloscopy, along with blood group, can play a vital role in person identification.
