RESUME
A 26-year-old female patient came in for dental care for cosmetic restoration. Periapical and panoramic radiograph showed a lesion on tooth 14, with a mesio-occlusal composite resin restoration, pain on vertical percussion, and negative cold sensitivity test.

In the first appointment, was performed the coronary access with a diamond bur and a non-active tip drill (Endo Z, Angelus Prima), preparation of the cervical and middle third with Hedstroem hand files (Dentsply) and Gates Glidden #2, #3, and #4 drills (Angelus Industria de Produtos Odontológicos). Constant irrigation with 2.5% sodium hypochlorite was performed. Calcium hydroxide-based intracanal dressing and temporary restoration with IRM were used.

Two dressing changes were performed. After this period, the patient returned for the obturation. Instrumentation was performed with a reciprocating file (Reciproc Blue, VDW). For the obturation, MTA-based bioceramic endodontic cement – MTA-Fillapex – (Angelus Industria de Produtos Odontológicos) was used. The obturation was performed using the lateral and vertical condensation technique, and the tooth was then restored with IRM temporary restorative material (Dentsply).
