Role of Forensic Odontology in Identification of Persons: A Review Article

Abstract

Forensic dentistry plays a pivotal role in identifying deceased individuals when visual or other means of identification are not possible, particularly in the aftermath of mass disasters or criminal activities. Accurate and timely identification of the deceased and injured becomes crucial following events like earthquakes, fires, transport accidents, gunshot incidents, floods, tsunamis, bomb blasts, and terrorist attacks. The process of creating a person's identity is a formidable task, often relying on prevalent methods such as dental, DNA, and fingerprint analyses. Forensic odontology, a specialized field within dentistry, assumes a significant role in identifying individuals in accidents, civil unrest, natural and mass disasters, and crimes related to genocide. In cases where natural teeth are absent, the marking or labeling of dentures becomes essential for personal identification. Teeth's resilience to destruction and decomposition makes dental identification feasible even under extreme conditions. The fundamental principle of forensic dentistry rests on the uniqueness of each individual's oral structure, emphasizing that no two mouths are identical, not even in the case of twins. The purpose of this review is to explore the role of forensic dentistry in identifying individuals through various methods such as denture labeling, cheiloscopy, radiographs, bite mark analysis, rugoscopy, salivary signature, age and sex estimation, dental DNA identification, individual characteristics, and denture marking. Based on detailed ante-mortem records from dental specialists, which are compared to postmortem data during investigations, forensic dentistry is a trustworthy technique for identifying deceased individuals and criminals.
