Pulp and periapical tissue diseases. Periradicular abscess without fistula. Pathological resorption of teeth.

When the pathological process affects the dental pulp of the deciduous dental element and causes pulp inflammation or infection, endodontic treatment is indicated. 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 the endodontic treatment of a deciduous lower molar with furcation lesion, root resorption and permanent premolar agenesis. A patient was selected at the dental clinic of FAPAC/ITPAC (Porto Nacional) – TO, asymptomatic, negative sensitivity test and vertical percussion, incomplete root formation, radiolucent area in the furcation region in a deciduous lower molar and root resorption. In the first session, anesthesia, access surgery, absolute isolation, irrigation with 2.5% sodium hypochlorite, odontometry, instrumentation with K-files at 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 root canals were filled with mineral trioxide aggregate (MTA). Through the results obtained with the endodontic treatment, regression of the pathological process was noted during the proservations and the patient had no symptoms. Endodontic treatment in a primary first molar with a diagnosis of acute periradicular abscess is feasible for the conservation of the primary tooth. In this way, the absent permanent dental element performs its functions.
