A Treatment Method for Inflammatory External Root Resorption Based on Calcium Hydroxide and X-Ray Imaging Findings: A Case Report Study

Abstract

Purpose: This case report aims to describe a new treatment for severe inflammatory external Root Resorption (RR) using calcium hydroxide at different intervals, supplemented by X-ray imaging follow-up.

Materials and Methods: A 13-year-old boy reported the avulsion of his upper left central incisor. The tooth had been avulsed four months prior and was replanted forty minutes later by an emergency service. The canal was thoroughly irrigated with 2% sodium hypochlorite and then filled with calcium hydroxide of a creamy consistency as an intracanal medication due to its antimicrobial properties, using lentulo spirals. The calcium hydroxide was left inside the canal for a month. Following the diagnosis, treatment involved conventional endodontic therapy with calcium hydroxide dressings, and the root canal was definitively filled after radiographic control of the resorption.

Results: At the 6- and 12-month follow-ups, clinical and radiographic examinations revealed no signs or symptoms of any abnormalities. The resorption process had halted, and the radiograph showed the reappearance of the normal lamina dura, indicating successful therapy.

Conclusion: We demonstrated that our method, which involves using calcium hydroxide as an antimicrobial and anti-resorptive agent with X-ray imaging follow-up, can effectively result in complete treatment.
