To adjust the dental properties of polymeric restorative composite (PRC) with the resin matrix, ten different derivatives of bisphenol A glycerolate methacrylate (Bis-GMA) which is commonly adopted as a resin matrix component of commercial PRC products were explored. In this study, radio-opaque barium silicate was used as a sole filler (loading percentage; 76 wt%), triethyleneglycol dimethacrylate as a diluent of Bis-GMA, camphorquinone as a photo-initiator, and ethyl-4-dimethylamino benzoate as a photo-accelerator. At first, monomeric behavior of Bis-GMA derivatives studied herein was studied. Additionally, using the proper dental specifications, experimental results of the effect of molecular structure of Bis-GMA analogues on the dental properties of PRC were reported and discussed. |
