Background: Many elevations and depressions found on the external surface of the lip forming a characteristic pattern are called lip prints, the examination of which is referred to as cheiloscopy.
Aim: To determine the predominant lip print pattern in Rajasthani population of the Indian subcontinent.
Materials and Methods: 201 subjects of Rajasthani including 107 males and 94 females who met the inclusion criteria were included in the study and after application of a dark colored lipstick and impressions of the lips were taken on the self adhesive cellophane tape which were subsequently transferred onto bond sheets for analysis of lip prints patterns.
Results: Results of this study showed that most prevalent pattern in Rajasthani population was found to be type IV, followed by type I, type V, type III, type I’ and type II being the least prevalent. Statistical analysis with chi square test revealed no statistically significant differences were found among male and female subjects in their prevalence.
Conclusion: The most prevalent lip print pattern in Rajasthani population was found to be type IV, followed by type I, type V, type III, type I’ and type II being the least prevalent with no statistically significant gender differences. Further studies with large population groups will help in providing the practical applications of this identification method.
