Abstract

Background: External surface of lips has many elevations and depressions forming a characteristic pattern called lip prints, the study of which is known as cheiloscopy. This is unique for the individuals like in fingerprints.

Methods: The present study was conducted in 40 pairs of twins and their families to evaluate the possibility of variation of lip print patterns in twins and their parents to find out any similarity among twins and their families.  The twins were taken as the primary subject and their parents as the secondary subjects.

Results: The subjects with congenital lip deformity and any inflammation were excluded from the study. The lip prints were taken on the cello tape and highlighted with the black printer powder of Oddyessy make. the photographs were taken for the permanent record. The prints were studied on Adobe Photoshop 7.0 software and classified under Tsuchihashi classification.

Conclusions: Comparison of lip prints showed that they are unique to each individual and among twins revealed that they are similar but not identical and their characteristics resembled either parent. Since the lip print patterns are unique, lip print analysis can be considered as a tool for personal identification.
