Effect of conventional needle irrigation, passive ultrasonic irrigation, sonic irrigation and XP‐endo finisher in removing intracanal Vitapex paste

Abstract

AbstractTo compare the efficiency of conventional needle irrigation, passive ultrasonic irrigation, sonic irrigation and XP‐endo Finisher in removing Vitapex paste from root canals. The root canals of human single‐rooted teeth were prepared and obturated with Vitapex paste. After 2 weeks, the 48 teeth were randomly allocated into four groups: conventional needle irrigation (CNI) group, passive ultrasonic irrigation (PUI) group, sonic irrigation (SI) group and XP‐endo Finisher (XP) group. The specimens of four groups were scanned using a micro‐computed tomography after the Vitapex pastes was removed. The results showed that more residual paste was left in the CNI group than in the other three groups (p < 0.05). There was no significant difference among the PUI, SI and XP group (p > 0.05). And, the majority of the residual Vitapex was found in the apical third, with a small amount in the middle third after using any of the three agitated irrigation techniques.
