The finding that indicates a suspect’s bitemark is definitely not made by them is characterized as exclusionary. This conclusion is reached through a forensic comparison of the bitemark in question to the dental impression of the suspect. An exclusionary result means that significant differences exist between the bitemark and the bite mark produced by the suspect, indicating that it cannot possibly have been made by that individual. This determination is essential in forensic science because it helps narrow down the list of potential suspects, thereby enhancing the accuracy of the investigation. In cases where the bitemark shows unique characteristics that do not match those of the suspect, such as size, shape, or arrangement of dental features, forensic experts can confidently conclude that the suspect is excluded from being the source of the bitemark. This contrasts sharply with terms like “consistent” or “possible,” which do not carry the same level of certainty and indicate that there may still be a connection or resemblance between the bitemark and the suspect's dental profile.
