Outline of Final Research Achievements

The experimental resin-modified glass ionomers for restorative filling including hydrophilic multi-functional monomer or 2-hydroxyethyl methacrylate (HEMA) in the cement liquid were examined. The mechanical strength and water absorptions and shear bond strengths to the bovine dentin with and without surface treatment of bovine dentin of the cements were determined. The mechanical strengths of the cement including hydrophilic multi-functional monomer in the cement liquid (Cement A) showed greater than those of the cement with HEMA in the cement liquid (Cement B). Cement A revealed significantly lower water absorption compared to Cement B. Cement A had significantly greater shear bond strength to bovine dentin with surface treatment than those of Cement B. The study suggested that the mechanical strength, water absorption and shear bond strength to bovine dentin of the resin-modified glass ionomers for restorative filling were affected by the resin component in the cement.
