Bonding to enamel has over 50 years of history.Enamel acid etching remains the most effective procedure for stable enamel bonding. Bonding to dentin has been the objective of several studies over the last 20 years. In the beginning, the research was to find an adhesive system that could interact with efficacy in dentin. As dentin bonding improved, removal of the smear layer became necessary. Although important improvements in bonding have been made in the last 30 years, note that the requirements of an ideal bonding system are quite similar to those indicated by Buonocore.
