Abstract

Background: Bite mark analysis is an important part of medicolegal investigations, providing objective documentation and interpretation of patterned injuries that may represent human bite marks. Conventional analysis commonly uses wax sheets, while intraoral scanners represent a more modern approach. However, it remains unclear which method yields more reliable results, and few studies have compared the interpretations from these techniques. Purpose: To determine the level of matching bite mark interpretation produced through wax sheet and intraoral scanner. Method: A descriptive observational design was conducted using 57 maxillary study models that met the inclusion and exclusion criteria. Each model was impressed into a wax sheet to record the incisal pattern and scanned with an intraoral scanner to obtain a digital record. The two outcomes were then superimposed and scored according to correspondence: Score 0 = no match with the suspect’s tooth pattern; Score 1 = 1–2 matching incisal patterns; Score 2 = 3–4 matching incisal patterns; Score 3 = 5–6 matching incisal patterns. Results: The research results showed a score of 0 at 0%, a score of 1 at 3.5%, a score of 2 at 8.5%, and a score of 3 at 87.5%. Conclusion: This study obtained 0% with a score of 0, 3.5% with a score of 1, 8.5% with a score of 2, and 87.5% with a score of 3, indicating that the bite marks obtained from wax sheets and intraoral scanning demonstrated a high degree of similarity, and yielded comparable results

Abstract

Introduction: Forensic Odontology plays a crucial role in forensic investigations, including determining the postmortem interval (PMI). Rigor mortis is one of the early signs of death, often presenting challenges during oral examinations. Dental autopsy is a procedure that can address these challenges, enabling a thorough examination of the teeth even in the presence of rigor mortis. Review: Rigor mortis represents a major obstacle in dental autopsy procedures. Muscle stiffness hampers mouth opening and access to the oral cavity. Various techniques can be employed to perform dental autopsies in cases of rigor mortis, such as the use of mouth gags, trismus screws, and myotomy. Jaw resection techniques may also be employed to provide better access to dental structures. Conclusion: Rigor mortis significantly limits oral cavity access during dental autopsy procedures. Characterized by muscle stiffness, presenting a challenge during dental autopsy examination of the oral cavity.

Abstract

Introduction: Teeth are used as a primary method of forensic identification due to their robust nature. Although resistant to various environmental destruction, prolonged exposure to extreme temperatures may alter the tissue, rendering it fragile and prone to fragmentation. This poses a challenge for forensic odontologists in postmortem identification, as postmortem dental analysis often requires teeth to be intact for further investigation beyond the crime scene. This article aims to examine and discuss methods of teeth stabilization following exposure to high temperatures, focusing on materials selection and key properties for selecting the optimum stabilizing agents to preserve/reinforce the heat-affected teeth. Review: The literature review was performed using PubMed and ScienceDirect in accordance with the PRISMA workflow, including only full papers and original research and/or case reports. Various natural and synthetic solutions were effective for teeth stabilization, with spraying as the most effective method for maximum surface coverage. Aside from ease of use, material availability, rapid curing time, and non-volatility, the long-term durability and chemical stability are crucial factors in selecting the appropriate stabilizing agent to store heat-affected teeth for archiving. Conclusion: In conjunction with proper teeth stabilization methods, forensic odontologists must also consider proper storage of evidence, planning a safe route from the crime scene to the mortuary, and evidence storage time for possible future analysis to ensure the best evidence preservation.
