Cheiloscopy-Tool for Gender Determination in Forensic Odontology

Background: Fast and secure identification processes in forensic odontology can be a very difficult process. Probably the most common techniques used are Dental, fingerprint and DNA comparisons. Since these techniques cannot always be used, it is necessary to apply different and less known techniques such as cheiloscopy. Due to its special features, lip groove can be used successfully in human identification. Cheiloscopy can pivotal role in identifying unknown persons both dead and alive. Materials & methods: The present study was undertaken to ascertain the use of lip prints pattern in sex differentiation and evaluate differences in lip prints between males and females. Lip prints of 100 subjects , were obtained using lipstick and cello tape. The lip prints were analysed and classified according to Tsuchihashi classification. All the lip prints showed different patterns. Patterns of lip prints occurred in various combinations. Result: The patterns were not similar between males and females. Type 1, 1(a) were mostly seen in females whereas type 4 and 5 were seen most commonly in Males. Conclusion: For identification process cheiloscopy technique is still not widely used and is still in budding stage. Training programs and forensic dental education programs should be conducted in this regard. Oral pathologist can play a vital role as he is familiar with physiological and pathological features of oro-facial
