THE IMPORTANCE OF DEPROTEINIZATION IN DENTAL REHABILITATION

Abstract

There is many studies and literature that demonstrates that the objective of deproteinization is to increase adhesion to enamel. Deproteinization of enamel prior to acid etching allows phosphoric acid to enhance its action on the enamel surface by increasing etching, generating greater retention, marginal sealing, and excellent long-term clinical results. This new procedure should be added to the enamel adhesion treatment protocol. NaOCl denaturants proteins and does not cause changes in the mineral structure of the enamel. In addition, it increases the quality of the etching pattern by removing organic matter and the lm acquired from the enamel surface. This clinical procedure is an indispensable tool that optimizes the results of the conventional etching technique, to achieve greater morphological conditioning and generalized undercut areas on the enamel surface, by allowing an increase in the retention of resin-based materials. The success of a good adhesion is achieved through the retentive capacity achieved during a correct etching of the enamel, for which it is required that the entire surface of the enamel have an adequate etching pattern that allows optimal etching
