Abstract :Objective: The purpose of this study was to compare the efficacy of Erbium, chromium-doped yttrium, scandium, gallium and garnet insert ignore into journalissuearticles values(Er,Cr:YSGG);, and Erbium-doped yttrium aluminum garnet laser insert ignore into journalissuearticles values(Er:YAG); lasers with passive ultrasonic irrigation insert ignore into journalissuearticles values(PUI); and conventional syringe irrigation insert ignore into journalissuearticles values(CSI); for the removal of calcium hydroxide [Cainsert ignore into journalissuearticles values(OH);2] paste from standardized canal irregularities. Methods: Forty single-rooted human teeth were split longitudinally, forming halves, and cut a standardized groove in canal walls. After filling each groove with Cainsert ignore into journalissuearticles values(OH);2 paste, the teeth were reassembled and stored for 1 week. Cainsert ignore into journalissuearticles values(OH);2 was removed with CSI by using 10 milliliters insert ignore into journalissuearticles values(mL); of 5% sodium hypochlorite insert ignore into journalissuearticles values(NaClO); and 10 mL of 17% ethylenediaminetetraacetic acid insert ignore into journalissuearticles values(EDTA);, respectively. The teeth were randomly divided into four groups insert ignore into journalissuearticles values(n=10);. CSI group was irrigated with10 mL of 5% NaClO, 10 mL of 17% EDTA, and 10 mL of distilled water with CSI insert ignore into journalissuearticles values(control group);, respectively. In Er:YAG group, 5% NaClO was activated with Er:YAG laser, and in Er,Cr:YSGG group, Er,Cr:YSGG laser equipped with Radial Firing Tip 2 insert ignore into journalissuearticles values(RFT 2); was used. In the PUI group, PUI was used with 2.5% NaClO. All groups received irrigation with 10 mL of distilled water as final irrigation. The root halves were examined with a stereomicroscope using a 4-grade scoring system. Results: Residues of Cainsert ignore into journalissuearticles values(OH);2 in artificial grooves were observed in all groups. In Er,Cr:YSGG group, only three specimens got a score of 1 insert ignore into journalissuearticles values(less than half of the groove is filled);. Er,Cr:YSGG group was found slightly higher yet the difference was found to be not significant with other groups. Conclusions: Although Er,Cr:YSGG laser equipped with RFT 2 tip seems to have a superior effect on removing Cainsert ignore into journalissuearticles values(OH);2 from the standardized canal irregularities, there was no statistically significant difference between the applications.
