We investigated the efficiency of Endosonic Blue, EDDY, Ultra X and EndoActivator in removing calcium hydroxide from artificially created apical grooves in root canal walls. In Materials and Methods: A total of 60 single-root maxillary central incisors, root canals were created and the roots were divided into two longitudinal parts. In the most suitable root piece, artificial grooves were created in the apical section and filled with calcium hydroxide. Calcium hydroxide in the grooves was removed using EDDY, Ultra X, Endosonic Blue or EndoActivator, and the remnants in the grooves were examined under a stereomicroscope. EDDY and Ultra X removed significantly more calcium hydroxide than Endosonic Blue and EndoActivator. The performance of EDDY and Ultra X or Endosonic Blue and EndoActivator was comparable. Therefore, EDDY and Ultra X are more effective than Endosonic Blue and EndoActivator in removing calcium hydroxide from apical grooves in root canal walls. No technique could achieve complete calcium hydroxide removal.
我们研究了Endosonic Blue、EDDY、Ultra X和EndoActivator从人工制备的根管壁根尖沟中去除氢氧化钙的效率。材料与方法：选取60颗单根上颌中切牙，制备根管并将牙根分为两个纵向部分。在最合适的牙根片段中，在根尖段制备人工沟并填充氢氧化钙。使用EDDY、Ultra X、Endosonic Blue或EndoActivator去除沟内的氢氧化钙，并在体视显微镜下检查沟内的残留物。EDDY和Ultra X去除的氢氧化钙明显多于Endosonic Blue和EndoActivator。EDDY和Ultra X或Endosonic Blue和EndoActivator的性能相当。因此，在从根管壁根尖沟中去除氢氧化钙方面，EDDY和Ultra X比Endosonic Blue和EndoActivator更有效。没有一种技术能够完全去除氢氧化钙。
