| Outline of Final Research Achievements |
To determine the amount of calcium salt of MDP (MDP-Ca salt) developed during the adhesive application period to enamel or dentin, we designed a series of experimental MDP-based one-step adhesives with different amounts of MDP (EX adhesive). The effect of the concentration of MDP added in the EX adhesive on the types of the molecular species of MDP-Ca salts and their production amounts were examined. The enamel predominantly yielded mono-calcium salts of the MDP monomer and dimer, but in contrast, the dentin yielded di-calcium salts of the MDP monomer and dimer along with them. The amounts of MDP-Ca salt developed enamel and dentin increased with an increase in the amount of MDP added.
