Personal identification is an integral part of forensic investigation. DNA profiling, dental records and finger prints are more commonly used. However, these evidences may not always be obtained or used circumstantially. In such situations, other available evidences like lip prints (cheiloscopy), palatal rugae patterns (rugoscopy) etc may be employed due their uniqueness in different individuals and gender. This study aims to determine variations in patterns of lip prints and palatal rugae and thus ascertain the gender among 60 students of our institution It also aims at determining the reliability amongst the two methods employed. On doing this study we found that both the methods cheiloscopy and rugoscopy are equally reliable in sex predilection.
