COMPARISON AND ANALYSIS OF BITE MARKS USING WAX IMPRESSION, RADIOPAQUE AND COMPUTER ASSISTED METHODS - A FORENSIC STUDY

Aim: To evaluate the best method of overlay generation out of three methods i.e.,wax impression, Radiopaque and computer assisted method.

Material and methods: 50 randomly selected casts from departments of prosthodontics and orthodontics in DivyaJyoticollege of dental sciences and research, Modinagar, Ghaziabad were used to compare three commonly used two dimensional overlay generation methods in bite mark analysis. Overlay production was done by wax impression, Radiopaque and Computer assisted methods. Finally, the overlays obtained by each method were compared.

Results: Chi-square test was used for comparison of wax impression, Radiopaque and computer assisted overlay generation methods,the scores obtained being highest in case of computer assisted overlays, thus making it the best method of overlay generation out of three methods.

Conclusion: we conclude that the method of computer assisted overlay generation is the best method among the three methods used in our study.
