IMPACTION OF MANDIBULAR THIRD MOLARS AND THEIR IMPORTANCE FOR HUMAN IDENTIFICATION: CASE REPORT

Abstract

Teeth are one of the last elements to suffer damage, as tooth enamel is highly resistant to physiological phenomena, such as decomposition, trauma and carbonization. Therefore, Forensic Dentistry plays a fundamental role in the process of human identification, which can be done by comparing ante-mortem (AM) and post-mortem (PM) records. The identity of the individual is reached when there is a positive correlation between them. Based on this, the objective of the study was to present a case report where impacted lower third molars helped the forensic dentist in identifying the victim, based on the comparison of an ante-mortem panoramic x-ray, with the records of the remains of a decapitated and charred individual during a rebellion in an agricultural penitentiary in State of Roraima (Brazil). During the analysis, it was possible to compare the remains where the dental elements were present, with the panoramic x-ray brought by the family. Coinciding points made it possible to positively identify this victim. Impacted lower third molars were proved to be of great value in the process of human identification, with dental documentation, especially radiographic images, being important auxiliary elements in arriving at the identification of an individual.
