Abstract
Background: Teeth are among the most resilient structures of the human body and frequently withstand high temperatures during fire incidents. Studies such as the spectrophotometric analysis published in Forensic Science International have demonstrated measurable colour changes in enamel and dentin following exposure to elevated temperatures. Awareness of these changes is crucial for dental undergraduates, particularly in forensic odontology.
Aim: To assess the knowledge and awareness regarding colour changes in teeth due to burning among dental undergraduate students.
Objectives:
1. To assess the level of knowledge and awareness regarding colour changes in teeth due to burning among dental undergraduate students.
2. To evaluate students’ knowledge about thermal resistance of enamel and dentin.
3. To assess awareness regarding progressive colour changes of teeth at different temperatures (e.g., 400°C and 700°C).
Methods: A cross-sectional questionnaire-based study was conducted among undergraduate dental students. A structured, validated questionnaire consisting of 15 close-ended questions assessing knowledge about thermal effects on teeth, colour changes, spectrophotometric analysis, and forensic relevance was distributed. Data were analysed using descriptive statistics and chi-square test to assess association between year of study and awareness level
