Full course description

The acid etch technique has truly revolutionized the clinical practice of dentistry since the first publication in 1955 by Michael Buonocore on his idea of bonding acrylic to tooth enamel. The first publication on the clinical potential of the procedure was Buonocore’s paper on pit and fissure sealant in 1967. Early composite restorative materials were marketed (1964) before the acid-etch technique was well known and so failures were common and the technique got a bad name in the eyes of some clinicians. The ‘70’s saw the early adapters embracing the technique and clinical procedures such as the Class IV resin gradually being adopted into the curriculum of dental schools and replacing the use of pins and other means of retention. Our profession is slow to adapt and even in the ‘80’s conservative preparations such as the Preventive Resin Restoration (1977) were not adopted by many dental schools with faculty who had not been trained in the procedures. The concepts of cavity preparation outline being determined by caries and not by G.V.Black’s principles, and restorative material that could be bonded and not requiring mechanical retention, took a long time to be accepted. As the technique spread to prosthodontics and orthodontics, the full extent of the revolution began to be realized. Today the acid-etch technique is an accepted and integral part of clinical dentistry—the battle for acceptance in the early days, however, was long and slow.
