title: [Repair and revision 7. Endodontic treatment of crowned teeth: restoration replacement, removal or trephining].
abstract: Endodontic complications with crowned teeth are not uncommon in the daily practice. When a tooth, restored with a crown or a fixed bridge, requires endodontic (re)treatment the dentist has a choice to either discard the restoration, remove it and recement it after endodontics, or to trephine the restorations. Discarding is indicated when clear shortcomings of the crown or bridge are encountered. Removal facilitates endodontic treatment. If removal is not feasible, an endodontic access cavity is prepared in the restoration. Based on case reports practical advice is presented in this article.
