ABSTRACT

The aim of this study is to assess in vivo the formation of hybridization and the marginal adaptation of one-stepself-etch adhesives.
In conjunction, etched enamel and adhesives provide excellent interaction, resulting in a strong adhesive-enamel bond and exceptional clinical results. Successful dentin bonding proved more complicated with the first generations of adhesives due to the presence of a smear layer. As dentin adhesion improved, it became necessary to remove the smear layer in the early stages; now it is not only necessary to remove the smear layer, but it is also essential to achieve sufficient dentin demineralization for proper adhesion. The changes in adhesives have led to a simplification of clinical procedures, and to self-etch systems replacing traditional etching. The results of this in vivo study show that both total- and self-etch adhesives display excellent marginal adaptation to enamel and dentin hybridization, thus ensuring the success of composite resin restorations.
