Outline of Final Research Achievements

The purpose of this study was to evaluate experimental primer containing vitamin and ferric ion on dentin bonding, and to analyze the bonding mechanism.
In conclusion, a primer containing tocopherol on dentin surface after AD gel (NaClO) treatment improved bond strength between 4-META/MMA-TBB resin and dentin.
