Outline of Final Research Achievements

The purpose of this study was to evaluate experimental primers containing electron carriers on adhesive bonding to dentin, and to analyze the bonding mechanism.
In conclusion, a primer containing a certain chlorophyll derivative (CLD) with 2-hydroxyethyl methacrylate (HEMA) improved bond strength between 4-META/MMA-TBB resin and dentin. In addition, differential scanning calorimetry (DSC) analysis revealed that CLD accelerated polymerization of 4-META/MMATBB resin depending on its concentration. Accordingly, it was suggested that CLD accelerates polymerization of monomers diffused into the etched dentin, which contribute high bond strength.
