Historical Evolution of Dentin Bonding Agents: A Clinician's Perspective

The development of dentin bonding agents has revolutionized the field of esthetic and restorative dentistry. Buonocore’s discovery on enamel acid-etching followed by description of hybrid layer by Nakabayashi et al are some of the major breakthroughs which are responsible for changing paradigms in adhesive dentistry.On the basis of mode of use,dental adhesives can be divided in generations. Currently, challenges lie in front of the researchers to develop products that not only bind to the tooth but also contain antibacterial, remineralizing and enzymatic-inhibitory properties that can increase the longevity of the adhesive procedures.This paper provides an insight into the historical evolution of dentin bonding agents
