Dental science has much to offer law enforcement agencies in the detection and solution of crime. The permanent teeth develop throughout the first two decades of life, and physiologic variations, pathoses, and the effects of dental therapy may be recorded in the hard tissues of the remaining dentition throughout life and beyond. It is the role of the forensic dentist to extract this information and use it in the identification of the unknown body. The teeth may also be used as weapons and, under certain circumstances, may leave information as to the identity of the biter. Analysis of bite marks is the second major responsibility of the forensice dentist. The general practitioner has a major role to play in providing the accurate dental records on which much of forensic activity is based.
