Abstract
The visible light-cured unfilled resins using the nine types of aromatic dimethacrylates were investigated to determine the effects of the monomer structure on selected properties. Analysis of the data indicated that the mechanical properties of these unfilled resins were much dependent upon the monomer structure. There was also a correlation between the water sorption value of the unfilled resins and the reduction in their mechanical properties under wet conditions. The results of this investigation indicated that the fluoro groups-containing dimethacrylate resin would be the effective resin system for visible light-cured dental restorative materials.
