Abstract

Background: In large scale disasters associated with fire the damage caused by heat can make medico legal identification of human remains difficult. Teeth, restorations, and prostheses all of which are resistant to quite high temperatures and can be used as aids in identification process. Aim: Aim of the study was to investigate the macroscopic and microscopic changes of teeth and several dental filling materials exposed to a range of high temperature (200-800°C). Dental restorations include filling materials, crown, and bridges. Materials and Methods: Restored and unrestored teeth were placed in a furnace and heated at a rate of 30°C/min and the effects of the predetermined temperatures 200, 400, 600, and 800°C were observed. Macroscopic and stereo microscope findings were observed. Results: Our results showed that teeth and restorative materials resist higher temperatures than theoretically predicted and that even when a restoration is lost because of detachment or change of state, its ante-mortem presence can be confirmed and detected by stereo microscopic examination of the residual cavity. Conclusion: We further conclude that a reasonably reliable estimation of the temperature of exposure can be made from an analysis of the teeth and restorative materials.
