In vitro evaluation of temperature change on the root surface after the removal of root canal filling

Abstract

This study aimed to compare the temperature changes occurring on the root surfaces after the removal of root canal filling with two different root canal sealers by two different reciprocating files. Sixty extracted teeth with a single root and canal were used in this study. After chemomechanical preparation, the root canals in the experimental groups were filled with gutta-percha and AH Plus or CeraSeal, while those of the control groups were filled with gutta-percha only. Resiproc or WaveOne Gold were used for the removal of the root canal filling. Temperature changes in the middle and apical third of the root surface were recorded by a thermal camera at different time intervals. Among the groups using the same sealer, the temperature rise observed on the root surface at the end of 90 s in the Resiproc groups was found to be significantly higher than that of the WaveOne Gold groups.
