ABSTRACT Bite marks can be recorded in violent crimes such as sexual offences, homicides, child abuse cases, Rape cases, and during sports events. Although bite marks of an individual do have uniqueness due to specific characteristics and arrangement of the teeth, when it comes to bite mark analysis, it is complicated by numerous factors, being presented as a challenge to the Forensic Odontologist. Forensic odontology has gained wide acceptance in the field of criminal justice because no two people have identical teeth. These are considered to be an expression of dominance, rage and animalistic behavior. The science of bite mark identification can be used to link a suspect to a crime. These marks are seen when teeth are used as weapons of anger, excitement and destruction. During struggles between assailants and victims, mostly skin of victims bear bite marks. The specific pattern of marks on victim‟s body gives a clue about the type of abuse.This paper also aims to address the physical, biological and psychological aspects of this important tool of evidence from the crime scene. Keywords - bite marks, forensic odontology, homicide, criminal trial, psychological. INTRODUCTION The bite marks is thought to have started with Sorup.
