Remineralising fluorine containing bioactive glass composites

The objective was to investigate the mechanical properties, fluoride release and apatite formation of resin based dental composites on a containing Bioactive Glass (BG) with without silylating agent. A SiO2–P2O5–CaO–SrO–Na2O–CaF2 BG synthesized by melt quench route. This glass commercially available inert (IG) were incorporated into light cured BisGMA-TEGMA resin. composite resins then evaluated in terms their ability form Fourier Transform Infrared spectroscopy (FTIR) scanning electron microscopy (SEM) following immersion artificial saliva at pH 4 (AS4) 7 (AS7). experiments performed silylation BG. compressive strength flexural determined after 1, 28 84 days AS4 AS7 media. FTIR spectra exhibited split bands approximately 560 600 cm?1 corresponding surface or under all conditions. SEM showed presence reacted layer particles AS7. significantly higher for silylated composites. strengths both non IG decreased upon immersion. exhibit reduced but still comparable existing
