Abstract
The pulp reactions to a dentin bonding system including dentin priming with an aqueous solution of 35% glyceryl methacrylate (GM) were examined by observing the pathological change in the pulp of dog teeth restored by the combination of enamel etching with phosphoric acid gel, dentin cleaning with neutralized EDTA solution, dentin priming with the GM solution, and a chemically activated composite mediated by a commercial dentin bonding agent. It is concluded that it is possible to effectively use GM, because no serious irritation was observed in the tested specimens, although slight regressive change was seen in the early stages after restoration.
