Objectives: The aim of this study was to synthesize visible light activated titanium dioxide (TiO2) nanoparticles using titanium nitride (TiN) by solution route to determine its antimicrobial activity against Staphylococcus aureus when combined with heat cure polymethyl methacrylate denture base resins (PMMA) in three different combinations. Methods: Visible light activated as-prepared TiO2 photocatalyst was synthesized by peroxide based solution route technique using TiN. Part of the as-prepared TiO2 was annealed and anatase form was obtained. Physical properties of the material were evaluated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X– ray spectroscopy (EDAX) and Fourier transform infrared spectroscopy (FTIR). TiO2 (3 w%, 5 w%)-PMMA composite samples (incorporated, precuring or post-curing coating) and unblended acrylic samples were pre.. View More»
