The dental practitioner is provided with a variety of post endodontic treatment options which range from invasive methods like full veneer crowns to least invasive and aesthetic procedures like bleaching.The most important parameter in non-vital bleaching is the placement of a barrier to prevent the resorption of the tooth which has a poor prognosis. The aim of this paper was to report a case of successful non-vital bleaching by using mineral trioxide aggregate (MTA) as a barrier, with follow up reports of two years. This article describes a one year follow up of a case of non vital bleaching which was performed on a root canal treated, discoloured, maxillary central incisor. By using mineral trioxide aggregate as a barrier, a mixture of sodium perborate and distilled water was used as the bleaching agent. The follow up visits showed significant improvement in the shade of the bleached teeth even after 24 months, with no evidence of resorption. This is the first paper to report on the use of MTA as a barrier for non-vital bleaching. The placement of a proper bleach barrier is the most important factor for successful intracoronal bleaching. Non vital bleaching can be considered as a safe, effective and non invasive treatment option in the management of endodontically treated, discoloured teeth.
