Preliminary studies concerning some natural extracts influence on dentin

ABSTRACTIn dentistry, one of the major problems is related to the adherence of the composite filling materials to the dentin. Presently, in order to enhance this adherence, different adhesive materials are used. The main cause for the filling failure is the marginal degradation appeared between the filling material and the dentin, due to the weak structure of the surface of the dentin. We propose here the treatment of the dentin with some natural extracts (enoxil and laurel essential oil) in order to improve its mechanical properties. The results showed that this treatment could improve the mechanical structure of the dentin.
