Endodonic Intervention in Single Session on Patients with Need for Endodontic Treatment

Endodontic treatments have evolved in order to prepare the root canal system to receive an airtight filling of this system and thus preserve the health of the periapical tissues and / or restore it, when affected by injuries. Such goals are achieved through obedience to an appropriate chemical-mechanical preparation of the root canals, followed by filling them. The aim of this study is to perform endodontic intervention in a single session in patients in need of endodontic treatment.Fifty patients were treated at the ITPAC / FAPAC - Porto Nacional multidisciplinary clinic, asymptomatic and in need of treatment or endodontic retreatment. In all cases, anesthesia was performed with 2% lidocaine, absolute isolation, irrigation with 2.5% sodium hypochlorite, preparation of the cervical third with the Logic 25/05 rotary system, confirmation of the working length and foraminal patency with locator foraminal Root Zx, instrumentation of the apical third with Logic 25/05 system, final irrigation with agitated 17% EDTA with 25 IRRS ultrasound insert (VDW Endo Ultrasonic Files, Endodontic Synergy, Munich, Germany) at a frequency of 30 kHz for 20 seconds, connected to a piezoelectric device.After complete chemical-mechanical preparation, the thermoplasticized filling was performed in a single session. Then, coronary rehabilitation with composite resin was performed. Proservations of 1, 3, 6 months were carried out to analyze the regression of the infectious process and repair of the apical third. In the immediate postoperative period, 15% of the patients had spontaneous pain, however the incidence of severe pain , flare-ups, was around 5%. At 6 months, all patients were asymptomatic and without fistulas, however, only 60% had complete resolution of the periapical radiolucent areas. Therefore, in the medium term, endodontic treatment in a single session provided 100% of clinical success, but reduced percentage of radiographic success.
