Influence of three different dentin bonding agents on the adhesion of composite resin to dentine–An in vitro study

The demand for aesthetic, durable and quality restorations has increased signifi cantly. Teeth should be unobtrusive and ideally minimally invasive reconstructed. It is a problem to get a permanent bond between the hydrophilic dentin and the hydrophobic composite [1,2]. Dentin adhesives play a key role in this [3-6]. In order to have feedback on the bond between composite materials and hard tooth substance, in vitro scientifi c studies are carried out. The experimental setups differ in many parameters in the studies and are therefore often not comparable.
