Adhesion or surface roughness and discoloration at the interface between pulpinsulating materials and composite resins were taken as indications for interaction between the resins and the insulating materials. Some interaction occurred between all insulating materials and resins investigated. After separation of the restorative resins, the interaction of Dycal with the different composite resins varied considerably and decreased in the following sequence: Opotow, Natural, and Adaptic. The interactions of ZOE with Natural and with Adaptic were similar and more pronounced than the interaction at the Adaptic-Dycal interface but less pronounced than at the Dycal-Natural interface. A very thin film of Tubulitec was found to adhere to the composite resins in some areas. The adherence of liners containing calcium hydroxide to dentin was found to be generally stronger than the bond between these liners and composite resins. Separation of the composite resins caused tears in the varnishes and frequently in Hydroxyline. Almost completely intact layers of the varnish Copalite were observed on dentin, but Zahnlack apparently dissolved to a great extent in the resins. Among the liners containing calcium hydroxide, Dycal and Tubulitec were found to give rise to a high pH in samples of saliva, but Hydroxyline did not. Porosity and a folded surface were observed for Hydroxyline, indicating the entrapment of the solvent beneath a dry superficial layer.
牙髓绝缘材料与复合树脂界面处的粘连、表面粗糙度及变色被视为树脂与绝缘材料之间相互作用的指标。在所研究的所有绝缘材料与树脂之间均发生了某种相互作用。在分离修复性树脂后，Dycal与不同复合树脂之间的相互作用差异很大，按以下顺序递减：Opotow、Natural和Adaptic。ZOE与Natural以及与Adaptic之间的相互作用相似，且比Adaptic - Dycal界面处的相互作用更明显，但不如Dycal - Natural界面处的明显。在某些区域发现Tubulitec的一层非常薄的膜附着在复合树脂上。发现含氢氧化钙的衬层与牙本质的黏附通常比这些衬层与复合树脂之间的粘结更强。复合树脂的分离导致清漆出现撕裂，在Hydroxyline中也经常出现。在牙本质上观察到几乎完整无损的Copalite清漆层，但Zahnlack显然在很大程度上溶解于树脂中。在含氢氧化钙的衬层中，发现Dycal和Tubulitec会使唾液样本中的pH值升高，但Hydroxyline不会。观察到Hydroxyline有孔隙和折叠表面，表明溶剂被困在干燥的表层之下。
