title: Nonvital tooth bleaching: guidelines for the clinician.
abstract: The combination of intracoronal and extracoronal bleaching represents a conservative treatment to restore esthetics to darkened or stained nonvital teeth. Notwithstanding the eventual risks and difficulties accompanying such technique, nonvital teeth often can be successfully lightened. This article presents a few guidelines for bleaching nonvital teeth as well as a clinical case to illustrate the indications and clinical protocol for the technique.
