| Research Abstract |
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.
