探讨了原子力显微镜(AFM)在牙科生物材料研究中的应用。讨论了两个基本点：第一是使用原子力显微镜对牙齿硬组织进行成像；第二是利用原子力显微镜研究液体粘结剂(Gluma)与牙本质的相互作用。结果表明，AFM可以很容易地对牙齿组织进行成像，并可以获得牙本质超微结构的高分辨率图像。至于牙本质粘接剂，有可能阐明Gluma的作用机制。特别是，观察到存在于Gluma混合物中的甲基丙烯酸羟乙酯在30秒内发生聚合。
The usefulness of atomic force microscopy (AFM) in the study of dental biomaterials was investigated. Two basic points were addressed: the first is the use of an atomic force microscope for the imaging of tooth hard tissue; the second is a study by AFM of the interaction of a liquid adhesive (Gluma) with dentin. Results show that dental tissues are readily imaged by AFM and that high-resolution images of the dentin ultrastructure can be obtained. As to the dentin adhesive, it was possible to elucidate the mechanism of action of Gluma. In particular, polymerization of the hydroxyethylmethacrylate present in the Gluma mixture was observed to occur in < 30 seconds.
