| Research Abstract |
Two types of monomer, differ in number of ethoxides and expected to possess lower viscosity and shrinkage, were used to make experimental light cure dental composites. The consistency, curing shrinkage and mechanical strength was investigated. The consistency of composites was decreased with the increase of more ethoxide monomer content. The composite made by the mixture in equal amount of two monomers showed similar strength to conventional bis-GMA base composites.
