title: Management of perforating internal root resorption with periodontal surgery and mineral trioxide aggregate: a case report with 5-year follow-up.
abstract: Internal root resorption (IRR) is characterized by progressive loss of tooth substance initiating at the root canal wall as a result of clastic activity. The use of periodontal surgery and mineral trioxide aggregate is a good approach to repair lesions with periodontal communication (perforating IRR). This case describes the treatment and follow-up of a maxillary central incisor with perforating IRR in a 56-year-old male patient where root canal treatment, periodontal surgery, and white mineral trioxide aggregate were employed to achieve complete repair and to restore function. Clinical findings and periapical radiographs indicated success after a 5-year follow-up.
