INTRODUCTION TO FORENSIC ODONTOLOGY
"TOOTH TELLS THE TRUTH"
Forensic Odontology is a vital branch of forensic science that involves the application of dental knowledge, primarily for identification of human remains. In this field, Forensic Odontologist deals with proper handling, examination, and evaluation of dental evidence, which will be presented in the court of law whenever required. Teeth have been used as tools and weapons since the advent of time, so a Bite mark can be inflicted by the individual during a violent act (such as sexual offences, homicides, child abuse cases, etc.) or it can be present on the accused body in a self-defence act. The arrangement, size and alignment of human teeth are individualistic to each person, this recognition and examination of the bite marks and their subsequent comparison with suspects, may lead to criminal identification.
