Abstract
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 Den- tistry 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 suspects dentition.

The identification of an individual from dental traces collected at the crime scene is one of the objectives of the criminal investigation
After reconstruction of the pattern of bite mark, the identification or exclusion from the suspected is based on a comparative scientific method, which must take into account the chain of custody and all the useful information related to this case study
The most important step in bite mark analysis is to recognize a patterned injury as a human bite mark followed by pattern analysis of the bite mark which provide the individual information about the suspect or an offender and relate the person who is involved in the crime
Summary
The identification of an individual from dental traces collected at the crime scene is one of the objectives of the criminal investigation. 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 [1]. The forensic analysis of a bite mark consists of detection, recognition, description and comparison of bite marks on either individuals or inanimate objects. The first question that arises is whether this injury is a bite mark or may have been caused by another factor. The second question, after establishing the injury as a bite mark and human, is whether it was caused by an adult or a child. The last question in the process of research identification, after recognizing trauma as a bite mark, if it is comparable to exclude or include - establishing the causal link with the subject, establish the identity of the perpetrator in a bite mark case [2]
