“…Animal bite marks differ in many aspects significantly from those caused by humans -but correct identification of the particular animal species or even dog race tends to cause a lot of problems, although-as it was mentioned before -even individual identification of a particular animal is possible in some cases [9]. It is possible in a significant part because of numerous macroscopically recognizable dental anomalies that cause differences in bite marks patterns -which was proven also by studies in humans [14]. In many cases the bite marks provide as unique and trustworthy identification as fingerprints thus they are very important to forensic activitiesthe methodology of acquiring and using this kind of data was developed primarily for the purposes of criminal inquiries and personal identification of humans.…”
