氢氧化钙化合物可以以各种形式获得，例如在水性悬浮液中或作为水泥、衬里、糊剂或填充树脂。当这些化合物暴露于水时，氢氧化钙解离，pH值变为碱性。在本研究中，对化合物Pulpdent、Dycal、Hydroxyline、Gangraena Merz和Prisma VLC-Dycal进行了分析，包括定量测量暴露于水后离子释放的量和时间进程，定性分析牙本质表面的碱化效应，并检查抗菌性能。结果表明，氢氧化钙化合物的差异很大。氢氧化钙水悬浮液（纸浆）的离子释放程度最强，结合明确的抗菌性能。骨水泥（Dycal）显示出明显较弱的活性。在实验条件下，内衬和糊剂（Hydroline和Gangraena Merz）以及氢氧化钙填充树脂（Prisma VLC-Dycal）在很大程度上缺乏离子释放和抗菌性能。
Calcium hydroxide compounds are available in various forms, such as in aqueous suspensions or as cements, liners, pastes or filled resins. When such compounds are exposed to water, the calcium hydroxide dissociates and the pH value shifts to the basic. In this study the compounds Pulpdent, Dycal, Hydroxyline, Gangraena Merz and Prisma VLC-Dycal were subjected to analysis, including quantitative measurement of the amount and the chronological course of ion release following exposure to water, qualitative analysis of the alkalizing effects at the dentin surface and examination of antimicrobial properties. The results showed that calcium hydroxide compounds differed greatly. The strongest degree of ion release, combined with definite antimicrobial properties, was found for the aqueous calcium hydroxide suspension (Pulpdent). The cement (Dycal) demonstrated significantly weaker activity. The liner and the paste (Hydroxyline and Gangraena Merz), as well as the calcium hydroxide filled resin (Prisma VLC-Dycal), were largely lacking in both ion release and antimicrobial properties under the experimental conditions.
