title: Assessment of endodontically treated teeth for restorative procedures.
abstract: This article describes a case report in which cementation of cast posts and cores in endodontically treated upper central incisors resulted in extrusion of zinc phosphate cement into the periapical tissues. This case demonstrates the necessity for careful evaluation of existing endodontic therapy before proceeding with the restorative phase of treatment. Some primary indications for endodontic re-treatment are suggested.
