Étude criminologique des morsures humaines : méthodes d’analyses tridimensionnelles des traces de morsure

Abstract : During sexual assaults, homicides or mistreatment, victims are sometimes bitten. Each person has their own unique set of teeth, thus bitemarks can be used to identify an individual. Their study is based on the comparison between the suspect's dentition and the tooth marks found on the victim. We evaluated the reproducibility and reliability of a three-dimensional analysis (photogrammetry, 3D camera and 3D scanner) compared to a two-dimensional analysis using photography. The files, obtained from bitemarks on the skin for each recording method and those from the dentition of three suspects, were compared visually and geometrically with the CloudCompare software. Photogrammetry has proven to be the best three-dimensional technique allowing us to exclude incorrect dentitions from the suspect list and to possibly identify a possible aggressor. Further research is needed to avoid certain biases and improve the analysis.
