ABSTRACT:
A new conservative method of conditioning enamel, dentin and other similar substrates, for obtaining strong and durable adhesive bonding of polymeric materials is disclosed. The method of conditioning addresses both the inorganic and organic phases of the tooth and is based on the concept of formation of a unitary polymeric network comprising the tooth structure and the restorative material, including an intermediary smear layer chemically modified and transformed into a stable, uniform and porous layer by rubbing the tooth surface with an aqueous solution of mild polyfunctional organic acids (pH=1.2-3.5).
