Abstract
A new functional monomer, 2-methacryloxyethyl hydrogen maleate (2 MEM), was prepared by the addtion of maleic anhydride to 2HEMA and its bond strength to polished and etched tooth surfaces under dry and wet conditions was measured and compared with that of 2-succinoxyethyl methacrylate [2SEM (control)]. The synthesized monomer was identified by elemental analysis, IR and NMR. The bond strength of 2 MEM to polished enamel was equivalent to or lower than that of the control under dry and wet conditions. However, the bond strength of 2 MEM to polished dentin and etched enamel and dentin under dry and wet conditions was higher than that of the control.
