ABSTRACT:
Hypersensitive dentin or cementum is treated by applying thereto two copolymerizable monomers which are polymerized in place and function to desensitize the hypersensitive areas. The first copolymerizable monomer used in the invention is the reaction product of N-phenylglycine or N- (p-tolyl)glycine and glycidyl methacrylate (NPG-GMA or NTG-GMA). The second copolymerizable monomer is selected from certain compounds produced by the reaction of an acid anhydride with excess hydroxyethyl methacrylate, e.g., biphenyl dimethacrylate. In a preferred embodiment, the mixture of monomers also contains a photosensitizer, such as camphoroquinone, which makes the mixture photocurable in addition to self-curable.
