The Role of Forensic Dentistry for Identification of a Criminal Sexual Assault: A Casework Report

Cristiana Palmela Pereira* and Jorge Costa Santos

The identification of an individual from dental traces collected at the crime scene is one of the objectives of the criminal investigation. When, at the crime scene, objects are found with tooth marks, the intervention of Forensic Dentistry may represent the only way to obtain positive identification of the author’s bite mark. The forensic analysis of a bite mark consists of detection, recognition, description and comparison of bite marks on either individuals or inanimate objects. In this medico-legal casework, a sexual assault, the victim of the crime presented to the forensic examination had a mark on her left arm consistent with a bite mark, probably from the aggressor during the crime perpetration. The protocol followed in this medico-legal casework study is a scientific analysis of the facts which when presented in the court will be defendable under ruthless cross-examination. The pattern association of dental features in this sexual abuse case demonstrated a degree of concordance present between the tooth marks in the victim’s body and the suspect´s dentition.
