Abstract :Background/aim: This study was aimed to evaluate the efficacy of removal of calcium hydroxide [Cainsert ignore into journalissuearticles values(OH);2] with the apical negative pressure irrigation system insert ignore into journalissuearticles values(EndoVac);, passive ultrasonic irrigation insert ignore into journalissuearticles values(PUI);, and needle irrigation using sodium hypochlorite insert ignore into journalissuearticles values(NaOCl);. Materials and methods: The root canals of 30 freshly extracted human mandibular premolars were used in this study. Each root canal was prepared with nickel titanium rotary instruments. Each root was split longitudinally through the canal. In one-half, a standardized groove was cut in the canal wall 2–6 mm from the apex, and filled with Cainsert ignore into journalissuearticles values(OH);2 paste. The roots were reassembled with plastic bracelets. Three techniques were used for Cainsert ignore into journalissuearticles values(OH);2 removal: Group 1, irrigation using the EndoVac irrigation system; Group 2, PUI; Group 3, needle irrigation; all used a total of 10 mL of 5% NaOCl as the irrigant. The amount of residual Cainsert ignore into journalissuearticles values(OH);2 in the groove was scored in accordance with previously reported criteria. The data were analyzed with the Kruskal–Wallis and Mann–Whitney U tests. The level of significance was set at p< 0.05. Results: No technique removed all Cainsert ignore into journalissuearticles values(OH);2. There were no significant differences between Groups 1 and 2, and Groups 1 and 3 insert ignore into journalissuearticles values(p< 0.05);. There was significant difference between Groups 2 and 3 insert ignore into journalissuearticles values(p> 0.05);. Conclusions: PUI was more effective in removing Cainsert ignore into journalissuearticles values(OH);2 paste from artificial root canal grooves, but the efficacy of PUI did not differ significantly from that of the EndoVac irrigation system.
