Four kinds of succinoxy methacrylates (2-succinoxypropyl methacrylate (2SPrM), 2-succinoxyethyl methacrylate (2SEM), 2-succinoxy-3-phenoxypropyl methacrylate (SPPM), and 2, 2-bis-(-4-(-2-succinoxy-3-methacryloxypropoxy)-phenyl-)-propane (Bis-SGMA)) were synthesized to improve the adhesive property of dental resins to tooth structure. Also the relations between concentration or chemical structure of these monomers and their adhesive property to polished and etched tooth surfaces were investigated.
The highest adhesion to unetched enamel surface after standing at room temperature and after soaking in water was obtaind with Bis-SGMA (50mol%), and SPPM (40mol%).
The highest adhesion to unetched dentin surface after standing at room temperature and after soaking in water was obtained with 2SEM (55-65mol%).
The highest adhesion to etched enamel and dentin surfaces was obtained with SPPM (40mol%), and Bis-SGMA (15-25mol%).
