A preoperative cone-beam computed tomography (CBCT) scan with high resolution (75 µ) revealed incomplete endodontic treatment and a large periapical radiolucency associated with tooth #2.2. The diagnosis was incomplete root canal treatment and symptomatic apical periodontitis. The CBCT showed complete calcification of the apical third of the tooth, and endodontic surgery was indicated as orthograde retreatment was not feasible. The patient's condition presented a complex case, as the calcification obstructed the endodontic space, making traditional orthograde retreatment useless. This situation necessitated the development and application of a new retrocleaning protocol.
