Establishing a person's identity can be a difficult task in cases of traffic accidents or in mass disaster situations. The records collected to identify a decedent should be accurate and totally inclusive of objective findings. When a victim has no teeth, information for use in personal identification based on methods available in forensic odontology is much more limited than in the case of dentate victims. Palatal rugae have been considered relevant for human identification due to its stability, which is equivalent to the fingerprint, in that it is unique for each ruga pattern. Palatal rugae appear to possess the features of an ideal forensic identification parameter, that is, uniqueness, postmortem resistance, and stability. The purpose of this article was to review the literature, in order to determine if there is enough evidence to establish the use of palatal rugae in dental identification.
Keywords: forensic; forensic dentistry; forensic odontology; palatal rugae; personal identification; ruga pattern.
