Composite resin full crowns which use composite resin and crown forms, have been used for pediatric dentistry. For use as a restoration material, an adhesive ability, aesthetics and easy handing are required. Recently, Geristore® which has the characteristics above besides fluoride releasing Glass ionomer modified composite resin, has been used in the clinic. However, the studies of application for full crown restoration have not yet developed. This investigation evaluates pulpal responses to composite resin full crown restoration using Geristore® on anterior teeth of dogs histo-pathologically.The following conclusions were obtained:1. Histopathological study revealed no severe pathological changes. Most of the pathological changes were hyperemia and slight round cell infiltrations. This may have been induced by the cavity preparation itself.2. Reparative dentin formation was observed in many cases.3. Pathological changes have decreased and reparative changes have increased with the passing of time.4. Histopathological evaluation revealed that 22 cases (95.7%) were successful and one case (4.3%)was fairly successful.The results of this investigation suggest that the composite resin full crown restoration using Geristore®m ay be considered safe for the pulp and clinically useful.
