Cheiloscopy–An Efficient Method for Gender Dimorphism

Abstract

Lip print is an anatomical character of the human lips. In forensic identification, lip print patterns can lead
us to important information and helps in person’s identification. The grooves present on human lips (Sulci
labiorum) are unique to each person and can be used to determine identity. Fingerprints, post-mortem reports
and of late, DNA fingerprinting, have been successful in person identification in the field of forensic science.
Just as in these method, lip prints can be instrumental in identifying a person positively and can be used to
verify the presence or absence of a person at the scene of crime . Cheiloscopic techniques have an equal
value in relation to other types of forensic evidences for personal identificationMaterial & method:- The
study was conducted on 100 students of age group 18-25 yrs. Lip stick was applied on each individual and
the lip-print was obtained on a paper. The lip impression patterns were studied, classified and recorded
using magnifying lens with light.Result:- Lip patterns are unique for the individual and no two patterns are
identical to each other . In study population,Type III pattern was most common in male while In females
predominant pattern was type I. Thus in medico legal case, due to clear differentiation in sexes it is easy to
identify person and gender. Conclusion:- Cheiloscopy can be reliable method for personal identification and
gender dimorphism.
