The workshop will address the practical aspects of bite mark analysis. It will address the issues of macroscopic and microscopic 3D pattern fit, both digitally and with the help of models. It will show how to capture the suspect’s bite, to be able to perform a one-on-one analysis of the bite mark evidence. The importance of weighting dental features within a specific population will be addressed with relevant case studies. All aspects of warping, shrinkage and distortion will be explained in the context of giving expert witness in court cases related to bite marks. The realities of cognitive bias will also be explained. The difference in analysis techniques between skin bite marks and those found in inanimate objects will be discussed and demonstrated. The interrelationship between microscopic analysis and the uniqueness of the dentition will be dealt with. The participants will be assisted in practicing the relevant techniques.
