Spreading Nanotechnology to Conservative Dentistry

将纳米铂胶（CPN）作为牙科粘接剂的粘接促进剂，可提高其对牙体表面的粘接能力。当在透射电子显微镜下观察树脂牙本质粘结时，通过观察粘结界面处的胶原纤维暴露的条件，发现粘结性能得到改善。CPN是公认的强氧化应激清除剂，但在某些条件下没有检测到清除作用。当CPN应用于破骨细胞系时，发现细胞的活性受到抑制。

Using Colloidal Platinum Nano-particles (CPN) as a adhesion promoter of dental adhesives increased its bond ability to tooth surface. When observing resin dentin bonds under the transmission electron microscope, improved bond performance was found by the condition that exposure of collagen fibrils were observed at the adhesive interface. CPN is well known as the strong scavenger for oxidation stress, but under the some conditions the scavenging effect was not detected. When CPN was applied to osteoclast cell lines, suppression of the activity of the cells was found.
