Much contemporary esthetic and restorative dentistry relies on bonding of resin‐based materials to tooth structure. Adhesion of resin materials to enamel has proved to be extremely strong and reliable since the concept was first introduced by Buonocore in 1955 and widely accepted by clinicians 20–25 years later. Enamel bonding is a simple and predictable process, because enamel presents a relatively homogeneous and largely inorganic substrate. Dentin, in contrast, is a heterogeneous tissue containing a large proportion of organic material and fluid, and is a difficult and variable substrate for bonding. Although clinically effective dentin adhesives have been available now for over 15 years, questions remain about the long‐term durability of resin bonds to dentin. This Critical Appraisal reviews some of the relevant literature on this topic.
