ABSTRACT

Introduction: Forensic Odontology allows human identification in cremation cases because teeth can resist very high temperatures compared to soft tissues and bones. Objective: To interpret the dental morphological changes produced in temperature ranges from 100° to 1100°C.
Methodology: Experimental in vitro study, the sample made up of 12 dental organs donated by patients with respective informed consent. They were randomly distributed into 4 groups of 3 teeth and each group was subjected to 100°, 500°, 1000° and 1100°C for 60 minutes using a Terlab muffle furnace. The teeth were subsequently photographed to visually evaluate the morphological changes.
Results: Significant effects were observed in the morphology of teeth subjected to different temperatures. At 100°C, no visible alterations were observed in the dental tissues. At 500°C, a change in color towards grayish tones was noted and porosity was observed in the roots. At 1000°C, changes in the coloration of the crowns were observed, preserving their morphology due to the presence of tooth enamel. However, the roots remained completely ash, indicating a significant transformation at this temperature. At 1100°C, complete destruction of the dental morphology occurred, including the enamel of the crowns. This indicates that this temperature leads to a drastic alteration in the tooth structure.
Conclusion: These findings are important for understanding how extreme temperatures can affect dental morphology and may have implications for forensic practice in situations of high temperature exposure.
