Abstract:
:Seven types of amide monomers, methacryloyl tyrosine amide (MTYA), p-methacryloxybenzamide (p-MBA), p-methacryloxybutoxybenzamide (p-MBBA), o-methacryloxybutoxybenzamide (o-MBBA), p-methacryloxybutoxy phenylpropionamide (p-MBPPA), 3,5-dimethacryloxybenzamide (3,5-DMBA), and 3,5-di (methacryloxybutoxy)benzamide (3,5-DMBBA), were prepared for use as bonding agents. The monomers were dissolved in HEMA. Bovine enamel was etched with 40% phosphoric acid, and bovine dentin was etched with 10% citric acid before being primed with MTYA.G.H. The tensile bond strengths between bovine enamel or dentin and experimental adhesives were measured after one day immersion in water at 37 degrees C. HEMA was used as a control adhesive. When bonding to etched enamel, the bond strengths of composite resins with o-MBBA and 3,5-DMBA were significantly higher than those with HEMA. The bond strengths of composites with MTYA, p-MBA, p-MBBA, 3,5-DMBBA and p-MBPPA were almost the same as those with HEMA. When bonding to dentin, the bond strengths of composite resin with MTYA and p-MBBA were significantly higher than those with HEMA.
