Abstract

With the ultimate aim of developing a novel optimal dentin-bonding system for Er:YAG laser-irradiated dentin, we investigated the adhesion-promoting effects of acid-conditioning and priming with hydrophilic monomers on the bonding performance of the resin-modified glass-ionomer bonding system (RMGI) to laser-irradiated dentin. Results showed that acid-conditioning with a solution of 10% citric acid and 2% ferric chloride followed by priming with 4-methacryloxyethyl trimellitic acid and 2-hydroxyethyl methacrylate was effective for improving the early bond strength and bonding durability of RMGI to Er:YAG laser-irradiated dentin.
