This study was performed to evaluate the physical properties (sealing, flow, radio-opacity, working time, and solubility) of a newly developed root canal sealer, CH61. It was compared with Canals, Sealapex, and AH26, which are typical commercially available root canal sealers. The sealing ability was evaluated by dye penetration. The flow was evaluated by two methods. One was flow in the vertical dimension, and the other was disk diameter. Radio-opacity, working time, and solubility were performed in accordance with the standards of the International Organization for Standardization. No dye penetration after immersion for 24 h was noted. In CH61, and there were significant differences between the values for CH61 and Canals, Sealapex, or AH26 (p < 0.001). For flow, the results differed from method to method. The radio-opacity decreased in the following order: AH26, Canals, CH61, and Sealapex. The solubility was the lowest for CH61. This study showed that CH61 had excellent sealing properties and low solubility.
本研究旨在评估新开发的根管封闭剂CH61的物理性能(密封性、流动性、射线不透性、工作时间和溶解性)。将其与典型的市售根管封闭剂Canals、Sealapex和AH26进行比较。通过染料渗透评估密封性。通过两种方法评估流动性。一种是垂直方向的流动性,另一种是圆盘直径。射线不透性、工作时间和溶解性按照国际标准化组织的标准进行测定。浸泡24小时后未观察到染料渗透。在CH61中,CH61与Canals、Sealapex或AH26的值之间存在显著差异(p < 0.001)。对于流动性,不同方法的结果有所不同。射线不透性按以下顺序降低:AH26、Canals、CH61和Sealapex。CH61的溶解性最低。本研究表明,CH61具有优异的密封性能和低溶解性。
