Abstract
The development of antibacterial dental resin using the silver methacrylate monomer (MAg) as an antibacterial substance was tried. The solubility of MAg in methyl methacrylate (MMA) was examined, and then the mechanical property of the polymer obtained by polymerization of MAg-containing MMA was tested. As a result, MAg was dissolved into MMA at a concentration of 84μmol/l, and it was suggested that the concentration was sufficient for the appearance of antibacterial activity. The resin obtained was transparent and colorless, and there was no esthetic problem. The compressive and bending strength of the resin were not significantly different compared with those of PMMA.
