Photocure bonding agent containing phosphoric methacrylate.
Effective photocure phosphoric methacrylate bonding agents which bonded a dental composite to tooth substrates were proposed. Methacryloyloxydecyl phosphoric acid (MDP) or 2-methacryloyloxyethyl phenyl phosphoric acid (Phenyl-P) was dissolved in triethyleneglycol dimethacrylate (TEGDMA) with camphorquinone (CQ) and N-phenylglycine (NPG). The combination of CQ and NPG was a good visible-light initiator for the polymerization. The highest bond strength was 5 MPa to dentin and 10 MPa to enamel when the adhesive contained Phenyl-P in TEGDMA. Dentin and enamel were recommended for demineralization with an aqueous mixture of 0.3 mol/L EDTA diammonium salt and 0.2 mol/L EDTA ammonium iron salt for generation of better bond strength.
