A cotton pellet soaked with a disinfectant solution under hydraulic temporary sealing material is expected to maintain aseptic conditions in the pulp chamber during root canal treatment. However, a disinfectant solution might hinder the setting of the hydraulicsealing temporary material. A soft material is likely to be worn and consequently collapse, and leakage will cause contamination of the pulp chamber. The aim of this study was to examine the effect of disinfectant solutions on the setting of hydraulic sealing cement. This research was able to consider the effects of the properties of temporary seal material, such as pH and expansion, and an disinfectant solution about temporary sealmaterial.It was investigated the technique of making minimum infection to treat the next time and it was suggested to control a dental loss.

在根管治疗过程中，在液压临时密封材料下浸泡消毒液的棉球有望保持髓室的无菌条件。然而，消毒剂溶液可能会阻碍液压密封临时材料的凝固。柔软的材料很可能被磨损并因此塌陷，并且泄漏将导致牙髓腔的污染。本研究的目的是检验消毒剂溶液对水硬性密封水泥固化的影响。本研究考虑了暂时封闭材料的pH值、膨胀性等特性以及暂时封闭材料的消毒液的影响，探讨了使感染最小化的技术，为下一次治疗提供了建议，并提出了控制牙齿脱落的建议。
