• Abstract: Endodontics, a specialty of dentistry, plays an essential role in maintaining oral health, with specific challenges when it comes to treating teeth with incomplete root formation, that is, those that do not fully develop their roots due to factors such as trauma, cavities, genetics or developmental problems. This makes these teeth more susceptible to infections. In treatment, there are two main approaches: apexification, used when there is pulp necrosis, and apexification , applied when the pulp of the tooth is healthy. In addition, there are two predominant techniques: a single session, which removes the infected pulp, cleans, shapes and fills the root canals in a single appointment, and multiple sessions, in which the pulp is removed in an initial session, followed by subsequent appointments to clean, shape and fill the canals. The objective of this study is to evaluate through a case report the endodontic treatment in a lower molar with incomplete root formation using the immediate technique. In the first session, anesthesia, access surgery, absolute isolation, irrigation with saline solution and 2% chlorhexidine gel, odontometry, instrumentation with rotary files at the working length, drying and insertion of intracanal medication (calcium hydroxide) were performed. In the second session (after 15 days), the intracanal medication was removed and the distal canal was filled with aggregated mineral trioxide (MTA) and the mesial canal was filled with gutta-percha and AH plus sealing cement . Follow-up was performed at 8 months and 1 year, and progression of mesial and distal root formation and asymptomatology were observed . It is possible to conclude that endodontic treatment in a lower molar with incomplete rhizogenesis through the immediate technique is feasible and presents favorable results.
