[Effect of adhesion promoting monomers on adhesion to ground dentin].
Effect of adhesion promoting monomers dissolved in photocurable bonding agents on adhesion to ground dentin was investigated. They were MDP, Phosmer-M and 4-MET. The effect of those monomers was compared with that of Phenyl-P. The bonding agents contained campherquinone (CQ) as a photosensitizer, N-phenylglycine (NPG) as a reducing agent and TEGDMA as a base monomer. Phenyl-P was the best adhesion promoting monomer among those studied monomers. MDP could not polymerize well enough to give good bond strength. Phosmer-M could permeate through the smeared layer but could not make a stable resin reinforced dentin. 4-MET did not permeate through the smeared layer and did not adhere to ground dentin.
