项目摘要

It was reported that 10-MDP promoted formation of self-assembled layering at resin- hydroxyapatite interface when it was applied. Firstly, this study showed that the commercial 10-MDP based adhesives also formed the self-assembled layering of two 10-MDP molecules, joined by stable MDP-Ca salt formation, at the interface between human dentin and resin as similar to 10-MDP solution. The three-dimensional observation with FIB-SEM revealed that MDP-Ca salt was formed at the interface, extending into the adhesive (resin) layer. When we prepared adhesives containing MDP-Ca salts as a model of adhesion layer and measured its properties, polymerization shrinkage decreased and some of properties increased by adding the salt. It is concluded that MDP-containing adhesives do form nano-layering at the adhesive interface and MDP-Ca salt spread through the adhesive layer. The properties of adhesive layer with resin, salts and other residual tooth substances may influence the adhesion.
据报道,10-MDP 在应用时促进了树脂-羟基磷灰石界面处自组装层的形成。 首先,本研究表明,与 10-MDP 溶液类似,商用 10-MDP 基粘合剂也在人牙本质和树脂之间的界面处形成了两个 10-MDP 分子的自组装层,并通过稳定的 MDP-Ca 盐形成连接。 FIB-SEM的三维观察表明,MDP-Ca盐在界面处形成,并延伸到粘合剂(树脂)层中。 当我们制备含有 MDP-Ca 盐的粘合剂作为粘合层模型并测量其性能时,通过添加盐,聚合收缩率降低,并且某些性能提高。结论是,含 MDP 的粘合剂确实在粘合剂界面处形成纳米分层,并且 MDP-Ca 盐在粘合剂层中扩散。含有树脂、盐类和其他残留牙齿物质的粘合层的性质可能会影响粘合力。
