Adhesiveness of Glycidyl Methacrylate Derivatives Containing Hydrophobic Groups to Tooth Enamel

Abstract

For the development of novel dental adhesives, glycidyl methacrylate derivatives having substituted phenyl or fused polycyclic groups as hydrophobic groups were synthesized to study the effect of the structure on adhesiveness to tooth enamel. The monomers containing alkylphenyl groups showed higher tensile strength than those with fused polyring groups. Small alkyl groups such as methyl and ethyl groups on the aromatic ring tended to increase adhesive strength, but on standing, reduction in strength appeared to be inevitable. On the other hand, the long chain alkyl and phenyl substituents showed intermediate contribution to enhance ad-hesiveness without reduction in strength on standing.
