Abstract

Background: Bite marks show uniqueness due to specific characteristics and arrangement of teeth, but when it comes to bite mark analysis, it is complicated by numerous factors such as animal bite, abuse etc., Humans and pet animals (dog) bite marks analysis is by far the most demanding and complicated part of forensic dentistry. Aim: To analyze and compare bite marks of humans and the pet animals (dog) using indirect method, so as to assess its usefulness and application in forensic odontology. Materials and Methods: 40 samples including 20 humans (10 males and 10 females) and 20 dogs of different breed were included in the study. Bite registration of all the samples were obtained on modeling wax and intercanine distance were measured. Data were analyzed and results were tabulated. Results: Arch size and intercanine distance showed variable differences among humans and on average dogs showed more intercanine distance and arch size. Among dog breeds larger dogs showed larger variables when compared to smaller dogs. Conclusion: Assessment of bite marks evidences made by animals needs further investigation so that it can be a tool to assist the justice system to answer crucial questions.
