Objective.Antibacterial bonding agents are promising to hinder the residual and invading bacteria at the tooth-restoration interfaces.The objectives of this study were to develop an antibacterial bonding agent by incorporation of quaternary ammonium dimethacrylate (QADM) and nanoparticles of silver (NAg), and to investigate the effect of QADM-NAg adhesive and primer on dentin bond strength and plaque microcosm biofilm response for the first time.
