Forensic dentistry or forensic odontology involves the handling, examination, and evaluation of dental evidence in a criminal justice context. Forensic dentistry is used in both criminal and civil law. Forensic dentists assist investigative agencies in identifying human remains, particularly in cases when identifying information is otherwise scarce or nonexistent—for instance, identifying burn victims by consulting the victim's dental records. Forensic dentists may also be asked to assist in determining the age, race, occupation, previous dental history, and socioeconomic status of unidentified human beings. Forensic dentists may make their determinations by using radiographs, ante- and post-mortem photographs, and DNA analysis. Another type of evidence that may be analyzed is bite marks, whether left on the victim (by the attacker), the perpetrator (from the victim of an attack), or on an object found at the crime scene. However, this latter application of forensic dentistry has proven highly controversial, as no scientific studies or evidence substantiate that bite marks can demonstrate sufficient detail for positive identification and numerous instances where experts diverge widely in their evaluations of the same bite mark evidence. Bite mark analysis has been condemned by several scientific bodies, such as the National Institute of Standards and Technology (NIST), National Academy of Sciences (NAS), the President's Council of Advisors on Science and Technology (PCAST), and the Texas Forensic Science Commission. In India, certificate courses offered include a modular course by D. Y. Patil Vidyapeeth, Pune, and some other private entities. The Indian Dental Association offers a fellowship program in FO which can be either a classroom program or an online program. Master's degree programs in different forensic disciplines along with M.Sc. Forensic Odontology is offered by National Forensic Sciences University which is the world's only university dedicated to forensic sciences.
