| Outline of Final Research Achievements |
The adhesive restorative material is essential for dental treatment. However, there are some points to be improved in the material such as long-term durability. Recently, the development of adherent monomer, 4-MET linked with calcium (4-MET-Ca) were blended the one step bonding (HC). This study aims to develop MDP-Ca newly, and to investigate of new bonding material (MDCP) that MDP-Ca was blended into the all-in-one self-adhesive material comprising 4-META. MDCP formed excellent bonding layer, showed high adhesive ability compared to the control. MDCP was improved dissolution resistance and long-term durability of cured bonding material. Compared to the CMET, MDCP was no significant but showed superiority. It was suggested that MDP-Ca improved the adhesion strength in a different manner from 4-MET-Ca.
