Viscosity, Degree of Polymerization, Water Uptake, and Water Solubility Studies on Experimental Dichloro-BisGMA-Based Dental Composites

The objective of this work was to investigate the advantages using dichloro bisphenol A-glycidyl methacrylate (dCl-BisGMA) as a potential matrix for dental resin composites. A series model composites containing 65 wt% (urethane dimethacrylate/triethylene glycol dimethacrylate/BisGMA 1:3:1) and 35 silanated silica were prepared. Thus, BisGMA replaced by dCl-BisGMA 0, 25, 50, 100 obtain UTBC0, UTBC25, UTBC50, UTBC100, respectively. composites’ rheological properties, degree double-bond conversion (DC), water sorption (WSP), solubility (WSL) examined. data revealed statistically significant reduction in complex viscosity dCl-BisGMA, compared with UTBC0. No differences between DCs detected (p < 0.05). enhancement composite WSP also detected, conversely, WSL increased. Although viscosity, DC, characters enhanced, increase is an undesirable development. However, supposedly caused cyclization small flexible chains, which more likely occur presence hydrophobic monomers such prone leaching than are crosslinked networks. We concluded that monomer could potentially be used alternative or combination traditional monomers, including BisGMA, resin-based composites, it deserves further investigation.
