Apexification with Mineral Trioxide Aggregate Plug in the Upper Anterior Teeth: Presentation of Three Clinical Cases

Introduction: The aim is to describe the treatment of three immature permanent incisors associated to apical periodontitis, based on the placement of an apical mineral trioxide aggregate (MTA) plug for apexification. Case Series: Apexification was carried out by opening the pulp chamber, with debridement of the canal following anesthesia and isolation of the tooth. The canal was filled with pure calcium hydroxide in powder form, dissolved in saline solution for one week, and the aperture was sealed with IRM (Dentsply, Germany). One week later, the calcium hydroxide was removed and an MTA apical plug was positioned, sealing with a humid cotton pellet and IRM (Dentsply, Germany). After setting of the MTA, conventional endodontic treatment was carried out using gutta-percha, with definitive restoration of the tooth. Conclusion: All three cases, treated with MTA showed complete apical repair with rounding of the apex at radiographic control one year later, and the patients remained free of symptoms.
