The complete endodontic obturation of immature permanent central incisors with mineral trioxide aggregate and using obturated MTA as barrier for walking bleaching

The use of mineral trioxide aggregate (MTA) for both complete obturation and as a coronal barrier for non vital bleaching in immature maxillary central incisor is reported. A 18 year- old female reported with pain and discoloration of upper central incisors. Radiograph revealed immature maxillary central incisors. Single step apexification was done with MTA and root canal system eras obturated with MTA followed, by using this obturated MTA as a barrier for non vital bleaching. After 2 weeks esthetic management was done with direct composite. Follow up radiographs after 6months and one year revealed good bone healing and closure of the apex.
