Periradicular lesions are often associated with infections in the root canal system and can compromise periapical health if not properly treated. The aim of this study is to demonstrate the success of non-surgical endodontic treatment in the regression of these lesions by discussing the diagnostic process, therapeutic approach, and clinical follow-up of the patient.
This work presents a clinical case involving conventional endodontic treatment of tooth #15, in which the diagnosis was an acute periapical abscess in its early stage. The current protocols for instrumentation, irrigation, and root canal obturation were followed. After 13 months of follow-up, complete non-surgical regression of the lesion was observed, confirmed by tomographic, radiographic, and clinical examinations.
The success of the endodontic treatment highlights the importance of a correct and precise therapeutic approach, combined with continuous monitoring to ensure the healing of the periapical lesion.
