Suggesting a new therapeutic protocol for traumatized permanent teeth: Case report

Abstract

Introduction: The case reported herein consists of two teeth of one single patient, initially immobilized with a semi-rigid retainer used for 15 days without endodontic intervention. Objective: The aim of this article is to report a case of two teeth with extrusive luxation treated with a filling paste of calcium hydroxide, 2% chlorhexidine gel and zinc oxide. Methods: After a one-month followup, patient's teeth did not present evidence of pulp vitality. Radiographic examination revealed signs of external resorption. Endodontic treatment was carried out in association with a new treatment protocol using intracanal dressing applied in one single session and remaining in the root canal for four years. Results: The filling paste remained in the root canal for 24 months without being replaced. The case presented improvements in periapical lesions without inflammatory resorption. Conclusion: The filling paste proves to be successful and effective in treating traumatized teeth with root resorption.
