[Adhesive systems for tooth-colored restorations. A review].

The quality, longevity and the esthetic appearance of tooth-colored restorations are primarily dependent upon the integrity of the bond of the restoration with the enamel and dentin. Consequently, the enamel and dentin adhesives which are increasingly combined in the so-called adhesive systems play key roles in restorative dentistry. This paper describes the components, the clinical technique, the importance of the systems and the relevant adhesive mechanisms.
