Dentin Bonding Agents

The development and regular use of adhesive materials has begun to revolutionize many aspects of restorative and preventive dentistry. Attitudes towards cavity preparation are altering since with adhesive materials it is no longer necessary to prepare the cavity to provide mechanical retention through such features as dovetails grooves undercuts sharp internal angles in order to retain the filling. These techniques are therefore responsible for the conservation of large quantities of sound tooth substance which would otherwise be victim to the dental bur. Micro leakage a major dental problem which is probably responsible for many cases of secondary caries may be reduced or eliminated. These adhesive are therefore critical for the success of aesthetic materials restorative in modern dentistry. Adhesive dentistry has undergone great progress in the last decades. In light of minimal-invasive dentistry this new approach promotes a more conservative cavity design which relies on the effectiveness of current enamel-dentine adhesives.
