Endodoncia. 1990 Oct-Dec;8(4):147-52.
A case report is presented of an upper central incisor with incomplete endodontic procedure evidencing a radiolucent image that was treated by apicoectomy and retroamalgam. A year later the periapical lesion had healed completely but a new lateral radiolucency is observed. A reentry of the canal is performed eliminating the old obturating material, biomechanical preparation and obturation with sealer and thermo gutta-percha. The lesion was cured in nine months.
