Abstract :Objective: The aim of this study was to compare the efficacy of MTAD insert ignore into journalissuearticles values(a mixture of a tetracycline isomer, an acid, and a detergent);, Er:YAG laser, 17% EDTA, and 5.25% NaOCl in removing the smear layer from the surface of instrumented root canals. Materials and Methods: Various organic acids, instruments and lasers have been used to remove the smear layer from the surface of instrumented root canals. Twenty-eight extracted maxillary and mandibular incisors were prepared with rotary files. The teeth were randomly allocated to four treatment groups for final irrigation as follows: insert ignore into journalissuearticles values(1); 17% EDTA insert ignore into journalissuearticles values(followed by NaOCl);, insert ignore into journalissuearticles values(2); 5.25% NaOCl, insert ignore into journalissuearticles values(3); Er:YAG laser, and insert ignore into journalissuearticles values(4); MTAD. All teeth were processed for scanning electron microscopy insert ignore into journalissuearticles values(SEM); and the removal of the smear layer was examined in the apical, middle and coronal thirds. Results: At coronal location, NaOClinsert ignore into journalissuearticles values(2.2±0.4); group had significantly higher scores than MTADinsert ignore into journalissuearticles values(0.0±0.0);, EDTAinsert ignore into journalissuearticles values(0.6±0.4); and Er:YAG laserinsert ignore into journalissuearticles values(0.6±0.4); groups insert ignore into journalissuearticles values(p<0.001, p=0.039, and p=0.039, respectively);. At the middle third, NaOClinsert ignore into journalissuearticles values(2.6±0.5); scores were significantly higher than MTADinsert ignore into journalissuearticles values(0.0±0.0); and EDTAinsert ignore into journalissuearticles values(0.8±0.4); groups insert ignore into journalissuearticles values(p<0.001 and p=0.036 respectively);. At apical MTAD insert ignore into journalissuearticles values(0.4±0.3); group had significantly better scores insert ignore into journalissuearticles values(p<0.001);. Conclusion: The results of this suggest that MTAD is an effective final irrigator agent, particularly in the apical segment of the root canal, which presents challenges during cleaning.
