Introduction: Dental trauma is a common problem in childhood and may exert immense psychological impact on a child. Endodontic treatment of teeth with pulp necrosis and root resorption in the apical region can pose a major challenge to the dentist, especially at the stage of filling. Mineral trioxide aggregate (MTA) has been established in the literature as a material that allows placement of apical plugs, which mitigates the risk of leakage of filling material, thus reducing treatment time while stimulating tissue healing. Methods: This case report describes a successful root canal treatment after placement of an MTA plug on both maxillary central incisors after dental trauma and pulp necrosis. Results: Radiographs revealed successful treatment one year after root canal filling with MTA for apical sealing. Conclusions: Lack of an apical seal makes it difficult to obtain proper sealing of the root canal system, often resulting in apical surgery. The use of MTA as sealant in teeth with pulp necrosis and root resorption in non-circular canals in the apical region proved to be an effective alternative, given the physicochemical and biological properties of this material.
