| Research Abstract |
Using monomers which were developed for dentin remineralization, we evaluated their mineral-induction ability and short-/long-term dentin bond strength of resin containing the monomers, and observed adhesion interface. Moreover, we examined dentin adhesive property and sealing ability of material containing the monomer for inhibition of dentin hypersensitivity.
In results, it was found that addition of 5 and 10% of the developed monomer, AK-100 and TSM-47 to resin causes the deposition of apatite crystals in the adhesion interface, strong dentin adhesion, indicating long-term durability of adhesion interface.
Therefore, it was suggested that restorative treatment based upon minimal intervention to demineralized dentin might be possible by using the mineral-inducing monomers.
