Background. A bite mark left on different materials and surfaces such as food, chewing gum or the skin of dead or living persons and found at a crime scene can provide the crucial evidence required to secure a conviction in cases where neither fingerprints nor DNA are found. The most challenging factor in bite mark analysis is the interpretation of human bite marks left on the skin. This is due to both the specific character of skin – its elasticity and ability to distort – and the different shape and curvature of body parts and regions.
Objectives. To investigate the possibility of identifying a biter using 2D and 3D analysis of experimental bite marks and to check to what extent the characteristics of the material bitten influence the identification rate.
Material and Methods. The volunteers were asked to bite various materials of different structure and shape. The impressions of individuals’ dentition and wax bite registrators were taken in order to prepare dental casts. The samples of dental casts, corresponding bite registrators and bite marks from different materials were then scanned with 2D and 3D scanners, photographed, and finally examined and compared using computer methods.
Results. By comparing the characteristics of the teeth and experimental bite marks, it was possible to positively identify all individuals, but with different degrees of possibility. Negative results were obtained when comparing characteristics of teeth from one individual with the bite marks created by another individual who took part in the study.
Conclusion. When applied to experimental bite marks, both 2D and 3D methods proved effective in the positive identification of the biter.
