The restoration of endodontically treated teeth. Part 3. Cores

The functions and features of cores in restorative dentistry and the importance of preserving sound tooth tissue are discussed. The experimental and clinical support for a perceived superiority of cast post cores is reviewed. It is suggested that there is a need to re-evaluate this viewpoint, particularly when restoring posterior teeth. The materials currently in use are briefly discussed as well as research relating to possible core/luting agent interactions.
