Development of silica thin film coating method in the mouth with biosafety.

虽然有这么多的研究，牙科材料的替代牙齿，是由龋齿，有很少的研究有关的治疗和材料，以防止龋齿。如果牙齿表面覆盖有无色透明的二氧化硅薄膜，则可以预期预防龋齿。本研究的目的是利用陶瓷前体聚合物全氢聚硅氮烷（PHPS）作为二氧化硅前驱体，在牙齿表面形成二氧化硅薄膜，构建生物安全的二氧化硅涂层方法。用傅立叶变换红外光谱分析了PHPS转化为二氧化硅的转化率。结果，在施加3%过氧化氢溶液并用二氧化碳激光照射后，获得了显示转化二氧化硅的峰，考虑到生物安全性的二氧化硅转化方法已经成为可能。

Although there are so many studies into the dental materials alternative to the tooth that was removed by caries, there are few research related to treatment and materials for prevention of dental caries. If the tooth surface is covered with a colorless transparent silica thin film, it can be expected to prevent caries. The purpose of this study was to use the pre-ceramic polymer perhydropolysilazane(PHPS) as a silica precursor to form a silica thin film on the tooth surface, and build silica coating method of biological safety. The conversion from PHPS to silica was analyzed with Fourier Transform-infrared spectroscopy. As a result, after applying the 3% hydrogen peroxide solution and irradiated with carbon dioxide laser, a peak showing a conversion silica is obtained, silica conversion method considering biological safety has become possible.
