Introduction: Understanding of pulp cavity variations is necessary to guarantee success of endodontic treatment, which makes relevant the recognition of accessory canals in furcation areas (FC). Objective: The aim of this study was to report a clinical case of a mandibular first molar associated with extensive bone loss in furcation area with the presence of an accessory canal. Case report: Patient’s complaint was the appearance of “bubbles surrounding the tooth.” Clinic examination revealed fistula associated with pulp necrosis of tooth #36. There were no signs of periodontal disease. Radiographic evaluation demonstrated wide bone rarefaction in both furcation and periapical areas. After careful cavity access, a radiograph was taken, by means of which it was diagnosed that the FC connected the pulp chamber and the furcation area. Root canals were localized, followed by chemo-mechanical preparation. Periodic changes of calcium hydroxide were performed after 240 days, satisfactory repair was observed. After 270 days, the canals were filled and their openings as well as the FC sealed with MTA. The 360-day follow-up revealed absence of unwanted clinic signals and bone neoformation in the furcation area. Conclusion: The recognition of FC is essential in Endodontics, and so it is to identify its relationship with furcation lesions in teeth without clinical signs of periodontal disease. In these cases, proper decontamination of root canals system is capable of solving endo-periodontal problems, restoring patient’s health and avoiding unnecessary treatment.
