WebAcid etching of dentin is used by many bonding systems to remove the smear layer and permit bonding directly to the dentin matrix. Although early animal studies indicated that acid etching caused moderate to severe pulpal reactions, there is a high probability that the pulpal irritation may have been due to microleakage of bacteria and their products. WebNov 23, 2016 · 2. Adhesion. The advent of adhesion to hard tissues of the tooth defined a turning point and featured a new era in dentistry. The substrates more frequently available for adhesion in restorative dentistry are enamel and dentin. These mineralized substrates present distinct ultra-morphology and composition.
