ABSTRACT
Background: Study of lip prints is called cheiloscopy. Identification of the individual by the patterns of lip prints has emerged out as one of the most efficient methods in crime investigation. The patterns vary widely among individuals, even between the twins.
Aims and objectives: To study the patterns of lip prints in monozygotic and dizygotic twins and to compare their uniqueness.
Materials and methods: A pair of monozygotic and a pair of dizygotic twins who are all females of 18-20 years age were asked to apply lipstick. The lip prints were obtained by asking them to press a folded white paper in between the lips. Images were captured and analyzed.
Result: Monozygotic pair: twin-1-type 1 pattern with very few ridges in all quadrants; twin-2- type 5 pattern with no ridges. Dizygotic pair: type-1 pattern with nearly equal number of ridges in all 4 quadrants in both twins.
Conclusion: Though monozygotic twins with identical features, two types of patterns (Type-1 and type-5) were detected and same type of pattern (type-1) is seen in dizygotic twins who had different features indicating a variation from the observation.
Key words: Twins, lip prints, monozygotic, dizygotic.
