Aim: The aim of this study was to compare the efficacy of conventional syringe, passive ultrasonic irrigation (PUI), Navitip FX and EndoVac irrigation system in removing calcium hydroxide from standardized artificial grooves in straight root canals. Method: The root canals of 68 human mandibular premolars with straight root canals were prepared using Protaper Universal Rotary files (Dentsply Malleifer) up to size F4, and the teeth were split longitudinally. A lateral groove in the apical was prepared in each root half and filled with calcium hydroxide, and the root halves were reassembled. Four experimental groups of 15 samples each were established according to the removal techniques: group A; side vented needle; group B, EndoVac; group C, Navitip FX; group D, PUI. One positive control group and one negative control group of 4 samples each were also included in the study. The activation procedures were performed for 1 minute each with 10 mL 3 % sodium hypochlorite and 10 mL 17% EDTA as the irrigants. The cleanliness of the grooves was scored under 20 X magnification using a stereomicroscope. The median of scoring was analyzed using the Kruskal-Wallis test (P = .05). Results: PUI (median = 1) was significantly more effective in the removal of calcium hydroxide than the Navitip FX (median = 2), EndoVac (median=3) and conventional needle (median=3). There were no significant differences among Navitip, EndoVac and needle groups. Conclusion: the use of PUI system with the combination of EDTA and NaOCl enhanced Ca (OH)2 removal from apical third of root canals.
