Abstract
Adhesion promoters containing (meth)acryloyloxyethyl dihydrogen phosphate and/or di(meth)acryloyloxyethyl hydrogen phosphate and acidic (meth)acryloyloxyethyl esters of carboxylic acids can improve the adhesion of photopolymerizable tooth materials to the enamel and dentine. The very strong bonding to the dentine immediately after curing proves to be particularly advantageous.
