  Sandeep Kaur, Kewal Krishan, Preetika M Chatterjee, Tanuj Kanchan

Analysis of bite marks plays an important role in personal identification in forensic casework. Bite marks can be recorded in violent crimes such as sexual offences, homicides, child abuse cases, and during sports events. The arrangement, size and alignment of human teeth are individualistic to each person. Teeth, acting as tools leave recognizable marks depending on tooth arrangement, malocclusion, habits, occupation, tooth fracture, and missing or extra teeth. Bite mark identification is based on the individuality of a dentition, which is used to match a bite mark to a suspect. Bite marks are often considered as valuable alternative to fingerprinting and DNA identification in forensic examinations. The present review describes the classification, characteristics, mechanism of production, and appearance of bite mark injuries, collection of evidence, comparison techniques, and technical aids in the analysis of the bite marks.
