Introduction: Literature relates many classic case reports about anatomic variations of mandibular molars. However, few recent reports have shown treatments of mandibular permanent first molars in according to the current Endodontics view. Objective: This study aims to report endodontic treatment of a mandibular first molar presenting five root canals emphasizing the importance of an efficient decontamination. Clinical case: The endodontic treatment was performed through chamber access followed by localization and exploration of the root canals. Three canals in the mesial root and two in the distal root were noted. Following that, chemical and mechanical preparations were made with rotary and manual files, copiously irrigated with sodium hypochlorite 2.5% throughout all instrumentation. The obturation was made using the Hybrid Tagger technique and the definitive restoration was completed one week later. Conclusion: Knowledge of root canal system anatomy of mandibular first molars aggregates information in this area, as it will help dental professionals more successfully attempt endodontic treatment.
