Synthesize And Characterization of New Antibacterial Quternary Ammonium Bis-GMA for Dental applications

The objective of this study was to synthesize ionic dimethacrylate monomer (QABGMA) that contains quaternary ammonium groups (antimicrobial functionalities) and is compatible with the existing dental dimethacrylate-based monomers. The monomer was synthesized using the three steps reactions and incorporated at 15% (by mass) into a 50:50 (by mass) bisphenol A glycerolatedimethacrylate (BisGMA): triethylene glycol dimethacrylate (TEGDMA) resin. Characterization of synthetic materials and also degree of conversion (DC%) were performed using Fourier transform infrared spectroscopy (FTIR). This monomer is miscible and capable to copolymerization with dental monomer such as Bis-GMA and TEGDMA. The DC% of 15% QABGMA resin was slightly lower than sample containing 0% QABGMA.
