Abstract

The objective of the study was to evaluate the effects of dentin deproteinization protocols for post space using different formulations containing sodium hypochlorite before fiber post cementation with self-adhesive resinous cement. The groups were divided according to the irrigation protocol (DWC, SHS, SHT and SHG). The residue cleanliness, bond strength, adhesive failure pattern, and tag formation at the adhesive interface between the self-adhesive cement and the dentin were evaluated. For this, analysis in scanning electron microscope, push-out test and confocal laser scanning microscopy were performed. The SHT protocol showed the highest residue cleanliness on the dentin surface of the post space (p<0.05). In addition, SHT protocol showed highest bond strength and tag formation in the cervical and middle thirds (p<0.05). Dentin deproteinization with sodium hypochlorite with surfactant provided the best dentin cleaning of residues, bond strength and tag formation after cementation of the fiber post with self-adhesive cement.

液态、凝胶状或含有表面活性剂的 NaOCl 制剂对纤维后胶结前的牙本质去蛋白作用。

该研究的目的是评估在使用自粘树脂水门汀进行纤维桩固位前，使用含次氯酸钠的不同配方对桩间隙进行牙本质脱蛋白处理的效果。根据灌洗方案（DWC、SHS、SHT 和 SHG）将各组进行分组。对残留物清洁度、粘接强度、粘接失效模式以及自粘树脂水门汀和牙本质之间粘接界面的标签形成情况进行了评估。为此，使用了扫描电子显微镜、推出试验和共聚焦激光扫描显微镜进行分析。SHT 方案显示牙柱间隙牙本质表面的残留物清洁度最高（p

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
