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. In this direction, the DNA technology can be used in the recovery of the genetic material, through the saliva deposited in the skin, after the production of a bite mark, due to the fact that dental impression can be adulterated easily and showing problems on expert analysis. This literature review aimed to stand out the importance of the recognition of these injuries in practical skillful of the dentist, being emphasized the use of the DNA technology in the briefing of crimes.
