The authors studied, in vitro, by light microscopy and by morphometric analysis, the cleaning capacity of Dakin's solution, water and Tergentol, when used as auxiliary solutions to ultrasonic instrumentation of root canals. After irrigation and instrumentation, 15 extracted human mandibular incisors, with a single root and with only one canal, were submitted to routine histological processing with serial 6-microns sections stained with hematoxylin and eosin. The results showed that Dakin's solution energized by ultrasound leaves root canals with less debris than Tergentol; water falls into an intermediate position. The apical third showed more debris than the middle third, and none of the irrigating solutions left the root canals free of debris.
作者通过光学显微镜和形态计量分析，在体外研究了达金氏溶液、水和特洁恩多（Tergentol）用作根管超声器械辅助溶液时的清洁能力。在冲洗和器械操作后，将15颗单根单管的拔除人类下颌切牙进行常规组织学处理，制成连续6微米厚的切片，并用苏木精和伊红染色。结果表明，超声激活的达金氏溶液使根管内的碎屑比特洁恩多更少；水则处于中间位置。根尖三分之一处的碎屑比中间三分之一处更多，且没有一种冲洗液能使根管内完全没有碎屑。
