| Popis: | Background/aim: This study was aimed to evaluate the efficacy ofremoval of calcium hydroxide [Ca(OH)2] with the apical negativepressure irrigation system (EndoVac), passive ultrasonic irrigation(PUI), and needle irrigation using sodium hypochlorite (NaOCl).Materials and methods: The root canals of 30 freshly extractedhuman mandibular premolars were used in this study. Each rootcanal was prepared with nickel titanium rotary instruments. Eachroot was split longitudinally through the canal. In one-half, astandardized groove was cut in the canal wall 2–6 mm from theapex, and filled with Ca(OH)2 paste. The roots were reassembledwith plastic bracelets. Three techniques were used for Ca(OH)2removal: Group 1, irrigation using the EndoVac irrigation system;Group 2, PUI; Group 3, needle irrigation; all used a total of 10 mLof 5% NaOCl as the irrigant. The amount of residual Ca(OH)2 inthe groove was scored in accordance with previously reportedcriteria. The data were analyzed with the Kruskal–Wallis andMann–Whitney U tests. The level of significance was set at p 0.05).Conclusions: PUI was more effective in removing Ca(OH)2 pastefrom artificial root canal grooves, but the efficacy of PUI did notdiffer significantly from that of the EndoVac irrigation system. |
