| Research Abstract |
We have succeeded to produce the silica thin film on enamel surface via CO_2 laser irradiation on the perhydropolysilazane(PHPS) and hydrogen peroxide applied enamel. The produced silica thin film showed excellent micro-hardness, abrasion and acid resistances. This silica coating technique was also able to apply to the denture base resin(PMMA). And we have successfully synthesized a number of antibacterial silane coupling agents. Of them, 10-I had no cytotoxicity and offered advantages in antibacterial effect for the oral bacterial flora.
