A Case Report of Facial Bite Marks; Reference of Methods of Analysis

摘要

The trauma caused on the skin from the contact of the teeth with or without the contribution of the soft oral tissues (lips, tongue) is defined as a bite mark. They can be caused either by humans or by animals and are usually found in two kinds of cases: crimes and homicides with and without sexual activity and child abuse. Bite marks can be found on both victims and assaulters. In mortal combat situations such as the violence associated with life and death struggles between assailants and victims, the teeth are often used as a weapon. Indeed using the teeth to inflict serious injury on an attacker may be the only available defensive method for a victim. The frequency of occurrence of bite injuries at specific locations varies with the type of crime and sex and age of the victim. This case report aims to present a victim who was involved in a fight and the facial bite mark on the right part of the face was the only evidence for that. The concurrent methodology on collecting data from the mark and the possible suspect as well as the comparison techniques is also reported.
