RESUME
A 48-year-old female patient reported constant pain in tooth 11, which had recently undergone endodontic treatment, and the onset of edema in the vestibular region. The first session involved the removal of the filling material and refinement of the canal with Protaper Next rotary files (Dentsply). After complete removal of the filling material, irrigation was performed with 2.5% sodium hypochlorite and agitated with EasyClean (Easy). Next, EDTA was used, followed by 2.5% sodium hypochlorite, following the same irrigation protocol. The canal was dried, and calcium hydroxide-based intracanal dressing and temporary restoration were inserted.

In the second appointment, after 15 days, the intracanal dressing was changed, and in the last appointment, again after a 15-day interval, the canal was filled using MTA-based bioceramic endodontic cement (Angelus Industria de Produtos Odontológicos). The cement was dispensed on a glass plate in a 1:1 ratio, as recommended by the manufacturer, and manipulated until it acquired a homogeneous consistency. The finger spreader was embedded in the cement and inserted into the root canal, and the filling was performed using the lateral and vertical condensation technique, leaving the filling 2 mm from the cervical margin of the clinical crown. In the same session, the tooth was restored with composite resin and radiographed.
