To 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.
比较传统的针管冲洗、被动超声冲洗、超声冲洗和 XP-endo Finisher 从根管中清除 Vitapex 糊剂的效率。用人单根牙的根管进行准备并用 Vitapex 糊剂填充。2 周后，将 48 颗牙齿随机分配到四组：传统针管冲洗（CNI）组、被动超声冲洗（PUI）组、超声冲洗（SI）组和 XP-endo Finisher（XP）组。在去除 Vitapex 糊剂后，使用微计算机断层扫描对四组标本进行扫描。结果表明，CNI 组的残留糊剂多于其他三组（p<0.05）。PUI、SI 和 XP 组之间无显著差异（p>0.05）。而且，在用任何三种搅动冲洗技术后，大部分残留的 Vitapex 都在根尖三分之一处，少量在中三分之一处。
