Introduction to Bite Marks and their Forensic Significance
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.
