| Abstract | Introduction: When pulp tissue becomes necrotic while root development is incomplete (immature nonvital tooth), root development ceases, resulting in short roots with thin root canal walls that are prone to fracture. This presents a challenge in endodontic treatment. Roots at different developmental stages require different treatment approaches. This case report presents the treatment and outcomes of a premolar with open apex and nonvital pulp in a pediatric patient using MTA apexification.Case Report: A 12-year-old Thai female patient presented with purulent discharge from the gingiva at tooth #45, caused by fracture of dens evaginatus that penetrated the pulp horn. Treatment was performed by rubber dam isolation, access cavity preparation, root canal irrigation, working length determination, intraradicular medication, and temporary restoration. Subsequently, an apical barrier was created using MTA, followed by root canal obturation with gutta-percha and sealer, then composite resin restoration. Follow-up showed successful treatment with complete healing of the periapical lesion.Conclusion: Treatment of nonvital teeth with open apices using MTA apexification promotes healing of periapical lesions and can prevent the loss of permanent teeth in children. |
