A patient reported with pain and sinus opening in relation to a previously root canal treated maxillary central incisor. Intraoral radiograph revealed periapical radiolucency with shortening of root indicating external apical inflammatory root resorption associated with failed endodontic treatment. Nonsurgical re-treatment was started and intracanal calcium hydroxide (CaOH) was placed for four weeks. The tooth was obturated with Biodentine. At 6, 12, and 24 months follow-up, the patient was asymptomatic and radiograph revealed satisfactory healing. Inflammatory apical root resorption due to failed root canal treatment could compromise the root length and prognosis. Early arrest of such resorption is indicated by nonsurgical re-treatment using CaOH for root canal disinfection and obturating with bioactive material such as Biodentine, which results in the successful arrest of resorption and periapical healing.
