Open apex results hermetic seal which became difficult reach it. The closure of root apex is very essential for uccess of the endodontic treatment. On the other side, traumatic induce bleeding and decomposition products can penetrate the dentinal tubules and stain the surrounding dentin and enamel. That condition may lead teeth discoloration and make an aesthetic problem. Until now the apical barrier formation and healing still challenging in root canal treatment. Purpose: The aim of this case reports is to overview the closure of root apex in permanent incisor using MTA and to inform the result of internal bleaching treatment with walking bleach technique on the anterior permanent tooth due to trauma. Case: 21 years old female patient went to the Dental Hospital Faculty of Dentistry Airlangga University. The patient wanted to remove the discoloration on her anterior maxillary tooth. This tooth has traumatic history 17 years ago. On radiographic examination showed incomplete root formation with wide open apices and root canal at the same tooth. Case management: Apexification with MTA was performed followed by thermoplasticized gutta percha obturation and internal bleaching procedure with walking bleach technique. The final restoration is composite resin restoration. Conclusion: MTA can be a valid option for apexification rather than calcium hydroxide and intrinsic discoloration due to traumatic injury can be treated with walking bleach technique.
