摘要: The aim of this study was to asses in vitro the potential methacrylate-based adhesive resins containing niobium pentoxide (Nb2O5) for stimulating phosphate deposition. Adhesive were obtained by mixing 50 wt% BisGMA, 25 wt% TEGDMA and HEMA, Nb2O5 added on 2.5 or 5 wt% resin. Discs 6.5 mm diameter 1.5 mm height resin without presenting oxide inserting into a silicon matrix, followed photo activation. immersed simulated body fluid at 36°C 1, 7 28 days, then their surfaces examined Raman spectroscopy. Changes intensity 962 cm−1 peak, related bond, over samples’ used assess stimulate Experimental groups presented phosphate-rich layer deposition after 28 days SBF immersion, increased time. Incorporation provides promote resins.
