Simulated Body Fluid Sorption and Solubility of Silica Reinforced Dental Resin Composites

Abstract:

The aim of this study is to investigate the effect of filler loading on the sorption and solubility of Simulated Body Fluid (SBF) of self-prepared micro dental resin composites. The prepared resin composite was based on silica (SiO₂) particles and bisphenol-a-glycidyl methacrylate (Bis-GMA) as a base monomer and triethylene glycol dimethacrylate (TEGDMA) as a co-monomer. The filler was mixed with monomers, in proportions of 40, 50 and 60 wt.%. A resin matrix containing 0 wt.% filler was used as the control composition to evaluate the effect of filler loading on the sorption and solubility of SBF. The experimental methods were based on the procedure mentioned in the ISO 4049 (2009) standard for dentistry-Polymer-based restorative Materials. The sorption and solubility of resin matrix/SiO₂ composite decreased gradually as the filler loading increased. The increase of filler loading showed significant differences in the sorption and solubility as tested by ANOVA (P = 0.000).
