Esthetic and Endodontic Management of Discolored Non-vital and Retreated Maxillary Anterior Tooth with Conservative Approach: A Case Series

Abstract

Non-vital bleaching is a conservative approach to treat intrinsic discoloration of teeth of several etiology. Sodium perborate and hydrogen peroxide (H2O2) are the commonly used bleaching agents. The aim of this case series is to demonstrate the walking

bleach technique in non-vital and retreatment cases of maxillary anterior teeth. Maxillary central incisors were isolated with

rubber dam and root canal treatment was performed in non-vital teeth and amp; in retreatment cases after G.P retrieval. Barrier

space preparation was done using a heated instrument. Glass-ionomer cement was used as a barrier material. Mixture of H2 O2 /saline; sodium perborate was placed in canal; sealed with intermediate restorative material. After 1 week, the procedure was repeated to achieve the desired result. Walking bleach is a minimally invasive procedure to restore the esthetic of discolored non-vital; retreated tooth, however, care should be taken to avoid any post-operative complications.
