ENDODONTIC RETREATMENT PRECEDED BY INTRARADICULAR METALLIC PIN REMOVAL: CASE REPORT

Objective: The endodontic treatment has a high success rate, however technical, pathological or systemic factors can lead to failure. Front of this situation, the conventional retreatement should be considered as the first choice. The aim of this study is to present a clinical case of endodontic retreatment preceded by intraradicular metallic pin removal. Report case: A male patient, 27 years old, sought care due to the appearance of a fistula on the tooth 36, which had already submitted to endodontic treatment. The clinical examination revealed presence of resina restauration, showed a positive response to the vertical percussion, horizontal percussion and apical pressure tests in the referred tooth. Radiographic examinationrevealed coronary infiltration, partial filling in the ducts, periodontal ligament discontinuation, and extensive bone rarefaction in the furcation region and in the mesial and distal roots, besides a prefabricated pin in the distobuccal conduit. With prior consent of the proposed treatment plan and no impediment to the patient's systemic health, the non-surgical endodontic treatment was performed on tooth 36. Conclusion: The non-surgical endodontic retreatment is efficient for the maintenance of tooth function, and effective in the remission of signs and symptoms, beingtheproservationofgreatrelevance for the follow-up of the repair in the lesions.
