Management of Immature Apices in a Taurodontic Mandibular Second Permanent Molar: A Case Report

Aim:The aim of this case report is to document the successful apexification of a taurodontic, non-vital permanent mandibular second molar in a 13-year-old patient, utilizing calcium hydroxide (CaOH) as intracanal medication.Background: Immature taurodontic teeth with necrotic pulp present a significant challenge for conventional endodontic therapy.These cases require specialized treatment approaches to promote root development and closure of the apical foramen, essential for the long-term preservation of the affected tooth.Case description: A 13-year-old patient presented with a taurodontic, necrotic permanent mandibular second molar associated with pain.Following access opening and thorough cleaning and shaping of the canals, CaOH was applied as an intracanal medicament to induce apical root closure in both mesial and distal canals.Over a period of 10 months, successful root closure was observed, and the tooth was subsequently obturated.Conclusion: This case report highlights the successful apexification of a taurodontic, necrotic permanent molar using calcium hydroxide, with positive clinical and radiographic outcomes observed at a 1-year follow-up.
