Pulp diseases commonly happens because of the actions of bacteriological factors and show their characteristic signs and symptoms over the time. With pulp necrosis, a degenerative process starts and when there is no early treatment, it is possible to occur periapical lesions as a result of aggression to the pulp. In cases of periapical secondary lesions, clinical signs and symptoms persist and are related to secondary infection due to persistent bacterial contamination, also to operative factors, inadequate obturation or poor coronary restoration. This study aimed to report a case of endodontic retreatment and clinical and radiographic follow-up for 8 years, of chronic periapical abscess case, in which after retreatment, clinical signs and symptoms are no longer observed and bone neoformation is noticed.
