title: Nonvital tooth bleaching: a 2-year case report.
abstract: A discolored, nonvital maxillary right central incisor was bleached with sodium perborate and water, used as a "walking" bleach. An excellent result was obtained, proving the efficiency of both the intracoronal bleaching technique and the materials employed. A clinical evaluation performed 2 years later revealed that the tooth was slightly stained but esthetically satisfactory.
