Abstract

Purpose: This study aims to compare and evaluate the radiographic changes of extracted primary and permanent teeth, before exposure and after exposure to a range of high temperatures. Methods: The samples consisted of sixty teeth divided into two groups of thirty primary and thirty permanent teeth. Samples were subjected to periapical radiographs. Samples were exposed to different temperatures. Radiographs were taken after exposure. Qualitative evaluations of pre versus post-incineration radiographic images were done. Results: The results showed a number of significant radiographic details. At 200 degrees C there were no changes in primary and permanent teeth. At 400 degrees C fissures between enamel and dentin were found in crowns of both primary and permanent teeth, and at 600 degrees C fissures between enamel and dentin and within dentin in crowns of primary and permanent teeth were found, where as the roots of primary teeth showed fractures within the dentin and permanent roots showed relatively little changes. Conclusion: Primary teeth showed more radiographic changes at higher temperatures. Radiographic evidences can be obtained through the incinerated teeth of the deceased which will aid in identification of the victim in forensic investigation.
