dc.description.abstractThe purpose of this study was to determine safe parameters for intracanal laser irradiation, since excessive heat at the root surface may cause damage to the periradicular tissues. The effect of laser treatment irradiation on temperature rise and the morphological-related changes on root canal surfaces were determined using thermocouple probe measurements and scanning electron microscopy, respectively. Single-rooted, extracted teeth were irradiated with the pulsed Er:YAG laser (2.94 μm) using a 375-μm diameter fiberoptic probe placed in the root canal. Teeth were maintained in a 37°C water bath and temperature changes recorded as root canals were lased. Laser parameters were 40 mJ and 80 mJ/ pulse, measured at the fiber end, and repetition rate of 10Hz. The root canals were irradiated for four periods with 20-second breaks in between, slowly moving the laser fiber from the apical to coronal surfaces in a continuous, circling fashion at 2 mm/sec. The range of 2.0°C to 4.0°C temperature rise was measured. Laser parameters that produced temperature rise at the root surface below 10ºC were considered safe to the periradicular tissues during intracanal laser irradiation.pt_BR
