LONG TERM CALCIUM HYDROXIDE THERAPY FOR TREATMENT OF TRAUMA-INDUCED EXTERNAL ROOT RESORPTION: A CASE REPORT

Introduction: External inflammatory root resorption refers to the loss of cementum or dentin that sometimes extends to the pulp. The most common cause of this condition is trauma, but inflammatory lesions, tumors and occlusal excessive forces can contribute to it, too. The most common places for root resorption are the apical and cervical parts of the root. Case report: This article reports four formerly-traumatized teeth in a 14-yer-old boy with the diagnosis of pulp necrosis in teeth #8,9, as well as a primarily Uncertain pulpal condition of teeth #7,10, chronic apical periodontitis in all four teeth and internal and external root resorption of teeth #8,9. Long-term calcium hydroxide therapy was performed in order to stop the external resorptive process and all four teeth ultimately underwent root canal treatment. Conclusion: Long-term calcium hydroxide therapy can be an effective treatment option for stopping the inflammatory process of external root resorption before the obturation of the resorbed teeth.
