RESUMEN
The aim of this case report is to describe the treatment of a maxillary right central incisor with pulpal necrosis and incomplete root formation. The 14-year-old patient had experienced trauma to both maxillary central incisors approximately 2 years earlier. Therapy consisted of apexification with a bioceramic reparative cement to form an apical plug. After the clinical and radiographic evaluations, the clinician opened the crown, performed the chemical-mechanical preparation, and placed calcium hydroxide-based medication. At the next appointment, 24 days later, the intracanal medication was removed through passive ultrasonic instrumentation; the canal was dried; and the bioceramic cement was inserted into the apical portion with the aid of a mineral trioxide aggregate holder. A sterile cotton ball, moistened with distilled water, was used to maneuver the material in the apical region, and a periapical radiograph was exposed to confirm the correct placement of the bioceramic reparative cement. The canal was filled with gutta percha cones and a bioceramic root canal sealer. All procedures were performed with the aid of microscopic magnification. Clinical and radiographic evaluations at the 18-month follow-up visit showed that the treated tooth was asymptomatic, suggesting that the bioceramic reparative cement is effective for apexification.
