| Outline of Final Research Achievements |
We analyzed the chemical interaction of the phosphoric-acid ester monomer 10-methacryloyloxydecyldihydrogenphosphate (10-MDP) with zirconia using 1H and 31P MAS NMR and 1H→31P Heteronuclear Correlation (HETCOR) NMR, and determined the shear bond strength of composite cement to 10-MDP-treated zirconia. The shear bond strengt was significantly higher to 1ppb 10-MDP-treated zirconia than to untreated zirconia. The shear bond strengt increased with the concentration of 10-MDP. NMR revealed a 31P chemical shift of 10-MDP upon interaction with zirconia. 10-MDP improved SBS to zirconia in a concentration-dependent manner. NMR detected the presence of 10-MDP onto zirconia, even after being washed with acetone; 10-MDP chemically interacted with zirconia.
