Success of Endodontic Therapy of the Central Maxillary Incisor Internal Resorption – 3 Years Follow Up

Abstract

Introduction: A 40-year-old female patient fell and applied to our Clinic for the treatment of fractured crowns of teeth 21 and 11. The presence of enamel and dentin defects revealed without exposing the pulp on teeth 21 and 11. Tooth 21 was sensitive to vertical percussion with the presence of luxation. Vitality tests revealed absence of pulp sensibility and analysis of the retroalveolar radiograph showed presence of limited illumination in the region of the middle third of the tooth root canal. Chemomechanical treatment of the root canal was performed with Protaper Next instruments using 2% sodium hypochlorite for irrigation. Two weeks of intracanal medication with calcium- hydroxide followed. The canal was obturated with calcium silicate cement (Bioroot, Septodont, France) with gutta-percha points. One and three years later, no presence of pathological changes in the area of the lesion and the surrounding bone was observed, and the clinical examination showed that the tooth was asymptomatic and without luxation. Discussion: As a result of trauma damage to the predentin and odontoblast layers, the activity of osteoclastic cells intiates the process of root dentin resorption. Endodontic therapy of internal resorptions is challenging due to removing necrotic and well- vascularized granulation tissue and obturation of irregularly shaped defects. Conclusion: Adequate obturation and successful canal therapy with internal resorption can be achieved by using calcium silicate cements. Due to their positive properties (bonding in a moist environment, good edge sealing, osteodentine and osteocement potential), calcium silicate cements are the materials of choice in the rehabilitation of tooth root canal resorptions.Poster Presentation: PP-41Dostupno na: [https://e-bass.org/28thcongress/wp-content/uploads/2024/07/28thBaSS-AbstractBOOK-7.24.pdf
