Establishment of identity in the living and the dead individual carries tremendous medico-legal significance. Estimation of the age of an individual is an important step in establishing the identity of an individual. Identification may be complete or incomplete. Comparative techniques like anthropometry and prints involving foot, hand, nail, ear, lip, palate and fingers, superimposition technique, dental data and DNA fingerprinting help to identify an individual
