The access ionization attempt may occur during the coronary period, which may lead to a posterior dental access. The maintenance of the primary tooth is important, especially in cases of permanent tooth agenesis. The aim of this study is to report a clinical case about perforation sealing, endodontic retreatment, and installation of a fixed prosthesis in a lower molar. A patient was selected from the dental clinic of Fapac/Itpac Porto Nacional - TO, asymptomatic, negative sensitivity test and vertical percussion, need for retreatment and perforation in the furcation region. In the first session, anesthesia, access surgery, absolute isolation, irrigation with 2% chlorhexidine gel, identification of the perforation and its conditioning, odontometry, removal of gutta percha with rotary instruments (Logic RT system), drying and insertion of intracanal medication (calcium hydroxide) in root canals and perforation. In the second session (after 15 days), the intracanal medication was removed and the root canals were filled with gutta percha and plasticized technique, and the perforation was sealed with mineral trioxide aggregate (MTA). The clinical case was continued for 2 years, and during the follow-up, asymptomatic, periodontal tissues were clinically and radiographically normal and the dental element performed its masticatory functions satisfactorily. It is possible to conclude with this clinical case that even with a perforation in the furcation region and the need to insert a prosthetic rehabilitation in the dental element, the sealing of the perforation with the aggregate mineral trioxide allowed the maintenance of the dental element.
