Introduction: The success of intracavity bleaching in nonvital teeth is related to the ability of penetration or diffusion of the bleaching agent into dentin and enamel tissues. This manipulation can be done with some active ingredients as carbamide peroxide, hydrogen peroxide or sodium perborate. Some of the most popular techniques that can be used for this purpose are inside/outside bleaching technique, in-office bleaching, the walking bleaching tech-nique, thermocatalytic technique. Òhe carbamide peroxide gel is used in different concentrations. Recently this whitening agent is more recommended for use in intracoronal bleaching. Purpose: The aim of this case report is to show the quick effect of intracavity bleaching of the discolorated crown of nonvital central incisor, using a 45% carbamide peroxide gel. Material and methods: A modified walking bleaching method is presented in bleaching of a single discolored nonvital central incisor (11).
