Bitemark interpretation assumes that the human dentition is unique and that its attributes can be accurately transferred to skin. A cadaver model was used to investigate whether the correct biter could be determined from similarly aligned dentitions once the dentitions were impressed in human skin. One-hundred dental stone models, which were measured and determined to be unique, were divided into 10 groups based upon similarities of mal-alignment patterns. One model was randomly selected from each group and bites were produced on unembalmed human cadavers. Metric/angular measurements and hollow volume overlays of the models were compared with the bites made. The percentage of dentitions from each group as well as the 100 dental model population that could not be excluded as the biter was determined. Results showed difficulty distinguishing the biter from individuals with similarly aligned dentitions and in some cases, an incorrect biter appeared better correlated to the bite.
人类的牙列是独一无二的，并且其特征能够准确地转移到皮肤上。使用了一个尸体模型来研究，一旦将牙列压印在人体皮肤上，是否能够从排列相似的牙列中确定正确的咬人者。一百个经过测量且被确定为独一无二的牙科石膏模型，根据错颌模式的相似性被分成10组。从每组中随机选择一个模型，并在未防腐处理的人体尸体上制造咬痕。将模型的测量/角度测量结果和空洞体积叠加图与所制造的咬痕进行比较。确定了每组牙列以及这100个牙科模型总体中不能被排除为咬人的比例。结果表明，很难将咬人者与牙列排列相似的个体区分开来，在某些情况下，一个错误的咬人者似乎与咬痕的关联性更好。
