Dentists have come to realize that with proper endodontic therapy and adequate restoration, pulpless teeth can continue indefinitely as an integral part of the dental apparatus. And yet endodontic therapy should not be done on teeth that can not be restored. In this study 45 freshly extracted maxillary premolars were restored with prefabricated parallel post and subsequently restored with Amalgam, composite and Glass cermet. The teeth in each of the restoration groups were allocated to three different loading conditions, load at an angle of 10°, 45° and 90° to long axis of the specimen. It is observed that glass cermet core showed a mean failure load that was lower for all three loading conditions than those of Amalgam and composite cores. The aim of the study was to compare the bond strengths of Amalgam, composite and glass cermet cores restored with a pre-fabricated parallel post when subjected to simulated occlusal forces from varying angles.
