Abstract
Objective: This study evaluated the cleanliness of root canals and the adaptability of root canals filling material after using the XP Endo finisher (XP-F) and passive ultrasonic irrigation (PUI) during retreatment. Methods: 53 recently extracted mandibular premolars were used that were instrumented to a size 50 then blocks were grouped into; G1: Cleanliness (Cl) group and G2: Adaptability (Ad) group. The blocks in Cl group were sectioned longitudinally then reassembled and reinstrumented to a size 50. Then the canals in Cl & Ad groups were obturated then the root filling material was removed and canals were cleaned with XP-F or PUI. Furthermore, specimens in Cl group were evaluated using a digital microscope to image the remnants while canals in Ad group were reobturated and sectioned horizontally that were examined using push out test to evaluate adaptability and data were statistically analyzed. Results: When compared cleanliness of canals from remnants, there was no significant difference between subgroups. Furthermore, the AdXP-F and Adc subgroups had significantly higher values than AdPUI subgroup. Conclusions: Both XP-F and PUI perform the same with regards to removing of remnants. When using the XP-F instrument, the adaptability of the root canal filling material to the root canal walls improved.
