Five "cream-like" intermediary bases (Hypocal¿, Dycal¿, Reocap¿, Cavitec¿ and Dropsin¿) were studied using ZnO-eugenol (ZOE) and phosphate cement for comparison. The in vitro experiments, which were designed to reveal the penetration of a dye and an etching liquid, showed that Dropsin and Hyypocal were permeable to dye and that Dropsin was permeable to acid as well. The in vivo experiments revealed no definite differences between the different cream-like base materials, nor were there differences between those and the conventional cements. The overall mildness of the dentin-pulp reactions and the suitability of the rat molar for this kind of research are discussed.
使用氧化锌丁香酚（ZOE）和磷酸锌水门汀作为对照，对五种“乳膏状”中间基底（Hypocal¿、Dycal¿、Reocap¿、Cavitec¿和Dropsin¿）进行了研究。旨在揭示染料和蚀刻液渗透性的体外实验表明，Dropsin和Hypocal可使染料渗透，且Dropsin也可使酸渗透。体内实验表明，不同乳膏状基底材料之间没有明显差异，它们与传统水门汀之间也没有差异。文中讨论了牙本质-牙髓反应的总体温和性以及大鼠磨牙用于此类研究的适用性。
