Root perforating internal replacement resorption: a case report clinical with 10-year follow-up

ABSTRACT

This study aims to report a root perforating internal replacement resorption treated and followed up for ten years. A 19-years female showed in periapical tomography enlargement of the entire length of the root canal of tooth 11. The cone-beam computed tomography (CBCT) showed a hypodense area with jagged edges involving the pulp cavity space and communication with the periodontium. After being accessed and prepared, the canal and its resorption defect were obturated with mineral trioxide aggregate. The cervical third was sealed with glass ionomer, and the tooth was restored with composite resin. Ten years later, the tomography showed intact root canal filling and periapical and periodontal injury absence. The use of repair cement for root canal obturation with perforating internal replacement resorption is an alternative for these cases, being fundamental to have a clinical, radiographic and tomographic follow-up to evaluate the treatment success.
