[Adhesion of composite to dentin. Mechanical and clinical results]

Although an efficient bond of resin composites to enamel can be realized since quite a long time, reliable dentine bonding is nowadays still a clinical problem. After the failure of the dentine-etch technique, followed by the misfortunes of the chemical dentine adhesion technique, modern dentine adhesive systems are believed to function by a micromechanical attachment mechanism. Based on a morphological study of the resin-dentine interface, a broad selection of dentine adhesive systems was classified following their adhesion-strategy. In a second part, eight dentine adhesive systems were clinically tested in terms of retention.
