The current discussion about the importance of intracanal dressings and the effect of vehicles on calcium hydroxide pastes is justified by controversy concerning the achievement of complete disinfection after preparation of infected root canals and the real antimicrobial effect of these vehicles. The aim of this study is to investigate the role of vehicles in the antimicrobial effect of calcium hydroxide pastes. Well-conducted research about the characteristics of calcium hydroxide, such as antimicrobial potential, physico-chemical aspects and histocompatibility, gives credibility to the choice of this medication in several clinical situations. Different vehicles have been added to calcium hydroxide in an attempt to enhance its properties. Scientific reasoning indicates the use of hydrosoluble vehicles (distilled water, saline) associated with calcium hydroxide because of their chemical characteristics of dissociation, diffusibility and filling capability which are decisive for the biological behavior, i.e., antimicrobial qualities and induction of tissue repair.
目前关于根管内敷料的重要性以及载体对氢氧化钙糊剂效果影响的讨论，是由于在感染根管预备后实现完全消毒以及这些载体的实际抗菌效果方面存在争议而引发的。本研究的目的是探讨载体在氢氧化钙糊剂抗菌效果中的作用。关于氢氧化钙特性，如抗菌潜力、物理化学方面和组织相容性等的精心研究，使得在多种临床情况下选择这种药物具有可信度。已向氢氧化钙中添加了不同的载体以试图增强其性能。科学推理表明应使用与氢氧化钙相关的水溶性载体（蒸馏水、生理盐水），因为它们具有解离、扩散和填充能力等化学特性，这些特性对生物学行为，即抗菌质量和组织修复诱导起决定性作用。
