Revascularization of Upper Permanent Premolar With Two Canals

Abstract

Mineral trioxide aggregate (MTA) is a material that has been used in several clinical applications, such as apical barriers in teeth with immature apices, repair of root perforations, root-end filling, pulp capping, and pulpotomy. The aim of this clinical report was to describe successful revascularization procedure of an immature maxillary first premolar with apical periodontitis in a 10-year-old female patient. After preparing an access cavity, the tooth was isolated using a rubber dam and accessed. The canals was gently debrided using 5% sodium hypochlorite (NaOCl). And then MTA was packed into the canals. X-ray photographic examination showed the dentin bridge after the revascularization procedure. Thickening of the canal wall and complete apical closure were confirmed one year after the treatment. In this case, MTA showed clinical and radiographic success at revascularization treatment in immature permanent tooth. The successful outcome of this case suggests that MTA is reliable and effective for endodontic treatment in the dentistry.
