Abstract

This study evaluated the bonding performance of coronal dentin disks, designed for biological restoration, and CAD/CAM resin composite disks when bonded to flat dentin surfaces using dual-cure resin cements, with and without a resin-coating (RC) technique. Three distinct groups were established within the non-RC group, each using one of the two types of resin cements in a self-adhesive mode: one-step self-etch adhesive (1-SEA) without light-cure, 1-SEA with light-cure, and a separate group using an alternate cement. Within the RC group, a subgroup was established for each cement. The microtensile bond strength (μTBS) of the disk-dentin beam was tested after 0 and 10,000 thermocycles in a 5°C/55°C. No significant μTBS difference was observed among the non-RC groups. However, when using RC, the μTBSs of coronal dentin disks significantly exceeded those of CAD/CAM resin composite disks. Thermocycle aging did not affect μTBS in any of the bonding methods, except in self-adhesive mode.

用于生物修复的冠状牙本质盘和 CAD/CAM 树脂复合材料盘的粘接性能比较：树脂涂层技术的影响

本研究评估了使用双固化树脂水门汀与平整牙本质表面粘接时，使用或不使用树脂涂层（RC）技术，设计用于生物修复的冠状牙本质盘和 CAD/CAM 树脂复合材料盘的粘接性能。在非 RC 组中设立了三个不同的小组，每个小组都使用两种自粘模式树脂水门汀中的一种：不使用光固化的一步法自酸蚀粘合剂 (1-SEA)、使用光固化的 1-SEA 以及使用另一种水门汀的单独小组。在 RC 组中，每种粘接剂都有一个子组。在 5°C/55°C 温度条件下进行 0 次和 10,000 次热循环后，对圆盘-牙本质横梁的微拉伸粘接强度（μTBS）进行了测试。在非 RC 组中没有观察到明显的 μTBS 差异。但是，使用 RC 时，冠状牙本质盘的μTBS 明显超过 CAD/CAM 树脂复合材料盘的μTBS。除自粘模式外，热循环老化对任何粘接方法的 μTBS 都没有影响。

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.
