Abstract

A dental composition which when used together with a photopolymerizable dental sealing composition promotes adhesion of resin-based dental restorative materials to the tooth consisting of PA1 a solution of (i) at least one phosphate selected from the group consisting of methacryloyloxyethyl dihydrogen phosphate and bis-(methacryloyloxyethyl) hydrogen phosphate and (ii) a photopolymerization catalyst comprising camphor quinone and an amine, in acetone.
