Abstract
Introduction: Some procedures in Dentistry cause an increase in the external temperature of the root. If the temperature rise is above 10oC, permanent damage can be caused to the periapical tissues. The aim of this study was to perform the measurement of the temperature variation of the external root surface during the prosthetic preparation for fiberglass posts. Experimental procedure: 40 samples were divided into 4 experimental groups: G1: Non-fragilized and non-irrigated roots; G2: Non-fragilized and irrigated roots; G3: Fragile and non-irrigated roots; G4: Fragile and irrigated roots. The samples were placed in a plaster mold with a preheated water recirculation system at 39 ° C, simulating live conditions and followed by the prosthetic preparation for intraradicular post and the acquisition of data. Results and discussion: It was observed that there is a higher temperature increase in the apical thirds in all groups. Conclusion: All experimental situations demonstrated a critical pattern in relation to maximum established temperature variation of 10oC. In the groups with irrigation, the temperature increase control was satisfactory, but it was observed that the temperature difference is still reached in the first stage of operation, regardless of the subsequent effects of operation.
