Non-Vital Discolared Teeth Bleaching Using the Walking Bleach Technique: A Case Report

Abstract

Recently a visually pleasing smile has become a major concern for the patients; therefore, dental bleaching has gained importance due to its safety and great aesthetic results. A female patient presented with intrinsic discolorated maxillary central incisors after endodontic therapy. Maxillary central incisors were isolated with rubber dam and 2mm of the gutta-percha was removed in an apical direction beyond the cemento-enamel junction. Glass ionomer cement was used a barrier material. Mixture of hydrogen peroxide and sodium perborate placed in the pulp chamber and the teeth were temporarily restored with zinc phosphate cement. Following the treatment, a satisfactory aesthetic result was achieved. In this case, using the walking bleach technique was found to be successful in whitening discolared teeth after endodontic therapy. This method can be recommended as a safe alternative for treating with discolored devitalized teeth.
