Abstract:
The creation of buffer (hybrid) layers that provide improved adhesion to two heterogeneous materials is a promising and high-priority research area in the field of dental materials science. In our work, using FTIR and Raman microspectroscopy at the submicron level in a system of dental composites/intact dental enamel, we assessed the molecular features of formation and chemically visualized the hybrid interface formed on the basis of a nature-like adhesive, polydopamine (PDA). It is shown that a homogeneous bioinspired PDA-hybrid interface with an increased content of O-Ca-O bonds can be created using traditional methods of dental tissue pretreatment (diamond micro drilling, acid etching), as well as the subsequent alkalinization procedure and the developed synthesis technology. The development of the proposed technology for accelerated deposition of PDA-hybrid layers, as well as the creation of self-assembled biomimetic nanocomposites with antibacterial properties, may in the future find clinical application for minimally invasive dental restoration procedures.
摘要:
创建缓冲(混合)层,以提供对两种异质材料的改善的粘附力,是牙科材料科学领域的一个有前途且高度优先的研究领域。在我们的工作中,在牙科复合材料/完整牙釉质系统中使用FTIR和拉曼光谱在亚微米水平上,我们评估了分子特征的形成和化学可视化的混合界面形成的基础上的性质类似的粘合剂,聚多巴胺(PDA)。表明,可以使用传统的牙齿组织预处理方法(金刚石微钻孔,酸蚀刻),以及随后的碱化程序和开发的合成技术。提出的PDA混合层加速沉积技术的发展,以及创建具有抗菌性能的自组装仿生纳米复合材料,未来可能会发现微创牙科修复程序的临床应用。
