Abstract

Introduction: Cheiloscopy is the study of lip prints. Since the inception of the technique, the techniques
is being used to evaluate the individual identity and its association with sex determination. As the blood
stains may also be present at a crime scene, further studies have also been done to evaluate the association
of common blood group pattern with lip prints.
Aims and Objectives: To study the patterns of lip print and its association with blood group and gender in
adults.
Methods: In this prospective observational study, data were collected from 150 subjects (75 males and 75
females). All the subjects fulfilling the inclusion and exclusion criteria were in the age group of 18-30 years.
In this study lip print pattern samples were collected by paper fold method and blood group samples were
collected and both were analysed according to Tsuchihashi classification and Landsteiner’s classification
respectively.
Results: A The predominant lip print pattern found in males, females and both the gender together was Type
1- complete vertical in both upper and lower lips. Predominant blood group found in this study was B+ve.
Most frequent lip print pattern found in all blood group types was Type 1- complete vertical.
Conclusions: Our study revealed an association between distribution of lip print pattern and gender. There
was no correlation found in between blood group types and the cheiloscopic patterns. Further studies in
different populations with large sample size are required to obtain a more definitive picture and statistical
significance of this correlation.
