dc.description.abstractBackground and Objectives: Er,Cr:YSGG laser radiation is slightly better absorbed by hydroxiapatite than the Er:YAG laser and this fact may indicate its use as a benefit tool for caries prevention. This study was performed to investigate the surface and intrapulpal temperature during Er,Cr:YSGG laser irradiation at sub-ablative conditions. Study Design/Materials and Methods: Twenty five extracted human molar teeth were selected and divided into five groups, according to the following Er,Cr:YSGG irradiation conditions without air-water spray: 1.0; 1.5; 2.8; 5.6; 8.5 J/cm2 . During laser irradiation, surface temperature was measured using a thermocamera (ThermaCAM-FLIR SC3000). The pulpal temperature was also monitored by means of a thermocouple type T (copper-constantan) placed in the pulpal chamber. Results: The surface temperature increased directly with the energy density of laser, and returned to its initial temperature 3 seconds after laser irradiation. Laser irradiation resulted in a non-significant intrapulpal temperature increase ( 1C) in all parameters tested. Temperature rise values were compared using analysis of variance (ANOVA) with alpha equals 0.05. Conclusions: The application of laser irradiation did not induce detrimental surface and pulpal temperature variations at the utilized parameters, being suitable for caries prevention.
