B Background: Forensic odontology is an application of dentistry in legal proceedings, including bitemark cases. Bitemark evidence has been shown to assist with convictions in criminal cases, but has also provided false evidence in many instances. One of the dentists’ roles is to be able to identify bitemarks correctly. Preclinical students from the Faculty of Dentistry at Trisakti University are given forensic odontology lessons which includes the introduction of bitemark identification. Objective: To determine the accuracy percentage of bitemark identification by preclinical students from the Faculty of Dentistry at Trisakti University. Method: Descriptive observational study of 43 preclinical students from the Faculty of Dentistry at Trisakti University. Subjects were given 3 pairs of bitemark photos and dental casts photos, subjects then determined the bitemark definitions and then analysed the bitemarks by comparing it to dental casts. Statistical analysis were performed using the Receiver Operating Characteristics (ROC). Result: An AUC value of 0.56 was obtained, therefore the accuracy percentage of bitemark identification by preclinical students from the Faculty of Dentistry at Trisakti University was 56%. Conclusion: This study proves that the accuracy percentage of bitemark identification by preclinical students from the Faculty of Dentistry at Trisakti University is less than 70%, indicating poor accuracy.
