A significant field of study and analysis in Forensic Dentistry is the recognition and interpretation of marks and injuries produced for human bites in foods founded in crime scenes or in the human skin. In this way, the knowledge of the anatomical particularities of human dentition and distribution in the dental arcs can supply subsidies of real value to forensic scientist, sometimes, the only elements on which can count the expert. Particularly, in bite marks found in the skin, generally resultant of rapes, fights, assaults, abuses and child violence, this evidence can mean the crime resolution, assuming a decisive role in the criminal identification.
