| 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.
