Active Comparator
Er,Cr:YSGG Laser
Sodium hypochlorite
In laser group, each root canal was dried with paper points and then Er,Cr:YSGG (Biolase™, Waterlase™, San Clemente, CA, USA) was used for intracanal disinfection with the following parameters: panel output power of 0,75 W, pulse frequency of 20 Hz, and 1% water pressure to 10% air pressure ratio laser with RFT3 tips (415 µm diameter radial firing tip RFT3 Endolase, Biolase Technology, Inc; calibration factor of 0.85). The fiber was placed at 1mm short of the WL. Irradiation was delivered along the entire length of the root canal with helicoradial movements, 1mm per seconds in speed. This procedure was repeated three times and kept for 20 seconds between each irradiation.
In control group, each canal were irrigated with 6 ml of 2,5% NaOCl. For the final irrigation, 5 ml of sterile saline were used. During irrigation, needle was inserted 1 mm short of the WL.
