COMPARATIVE STUDY OF IMMEDIATE BOND STRENGTH AND AFTER STORAGE IN WATER: A LITERATURE REVIEW

Abstract

Adhesive systems are classifi ed according to different adhesive bonding approaches;
they can be either total or self-etch. However, the simplifi cation of the technique
and of the number of steps in the adhesive system should not affect its action over
time. Therefore, studies that evaluate the immediate bond strength and throughout
time have been carried out to evaluate the adhesive interface. To evaluate longevity,
storage in water or in other substances has been used as they can promote artifi cial
aging. Thus, the aim of this study was to review the literature about the reduction of the dentin bond strength after storage in water of both total-etch and self-etch
systems. After the literature review, it was observed that over time there is a decrease
in the bond strength for most of the adhesives; however, the decrease varies according
to the adhesive system used.
