AIMS
We evaluated and compared EndoActivator, CanalBrush, and passive ultrasonic irrigation (PUI) in the removal of calcium hydroxide and calcium hydroxide with iodoform and p-chlorophenol paste (Calcipast Forte) from artificial standardized grooves in the apical third of root canals.
MATERIALS AND METHODS
A total of 34 mandibular premolars were prepared and then split longitudinally. A standardized groove was prepared in the apical part of both segments. The grooves were filled with either calcium hydroxide or Calcipast Forte, and the segments were reassembled. CanalBrush, EndoActivator, or PUI were used. The amount of remaining medicament was evaluated using a four-grade scoring system.
RESULTS
None of the irrigation methods could completely remove the pastes from the grooves. More Calcipast Forte paste was detected compared with calcium hydroxide (P < 0.01). PUI was the least effective method in removing Calcipast Forte.
CONCLUSIONS
It was more difficult to remove Calcipast Forte than a water-based calcium hydroxide paste.
目的
我们评估并比较了EndoActivator、根管刷和被动超声冲洗（PUI）从根管根尖三分之一处人工标准化凹槽中去除氢氧化钙以及含碘仿和对氯苯酚糊剂的氢氧化钙（Calcipast Forte）的效果。
材料与方法
总共制备了34颗下颌前磨牙，然后纵向劈开。在两个牙段的根尖部分制备标准化凹槽。凹槽分别填充氢氧化钙或Calcipast Forte，然后将牙段重新组装。使用根管刷、EndoActivator或PUI进行冲洗。使用四级评分系统评估残留药物的量。
结果
没有一种冲洗方法能够完全从凹槽中去除糊剂。与氢氧化钙相比，检测到的Calcipast Forte糊剂更多（P < 0.01）。PUI是去除Calcipast Forte效果最差的方法。
结论
去除Calcipast Forte比水性氢氧化钙糊剂更困难。
