Abstract :
Background: Severe external root resorption, especially in teeth with unusual root anatomy, poses a diagnostic and treatment challenge. CBCT, calcium hydroxide, and MTA are effective in addressing these cases.
Case Presentation: A 10-year-old boy presented with a two-rooted maxillary central incisor and severe root resorption following trauma. Cone-beam computed tomography (CBCT) confirmed necrotic pulp and severe external root resorption in both maxillary central incisors. The right central incisor exhibited chronic apical periodontitis, while the left had a chronic apical abscess. Treatment involved long-term calcium hydroxide therapy and placement of mineral trioxide aggregate (MTA) apical plugs.
Results: At the six-month follow-up, the patient's teeth were clinically and radiographically stable, with no signs of pain, inflammation, or ongoing resorption. The left central incisor demonstrated successful healing, while partial healing was observed in the right maxillary central incisor.
Conclusion: This case illustrates the value of CBCT for diagnosis and the success of calcium hydroxide and MTA in treating severe root resorption.
