Özet
The purpose of this study was to investigate the evaluation of laser-assisted irrigation (LAI) on the removal of the smear layer as compared to passive ultrasonic irrigation (PUI). Forty-eight single-rooted, upper-central incisor teeth were selected and prepared with ProTaper rotary instruments up to size #40 (F4) at the working lengths. Specimens were divided into four groups, as follows: (a) PUI with 5mL of 2.5% NaOCl for 60s; (b) PUI with 2.5mL of 17% EDTA and 2.5mL of 2.5% NaOCl each for 30s; (c) LAI with 5mL of 2.5% NaOCl for 60s; and (d) LAI with 2.5mL of 17% EDTA and 2.5mL of 2.5% NaOCl each for 30s. In the PUI groups, the ultrasonically activated file was inserted 1mm short of the working length, but in the LAI groups, the fiber tip was applied into the pulp chamber. LAI in the pulp chamber with the combination of 17% EDTA and 2.5% NaOCl removed more of the smear layer than the other groups (p<0.018). LAI in the pulp chamber with the combination of 2.5% NaOCl and 17% EDTA better removed the smear layer than LAI applied similarly but without EDTA or PUI with the same NaOCl and EDTA combinations using an ultrasonically activated file inserted 1mm short of the working length.
