Brief summary
Aim to compare Incidence of flare-ups and apical healing after single-visit or two-visits treatment of teeth with necrotic pulp and apical periodontitis after a two-year control period. 110 teeth with a diagnosis of pulp necrosis and apical radiolucency at the apex. Working length was established with EAL and confirmed radiographically. M4 system with Flex-R files were used to complete canal preparation. Level of discomfort were recorded and cases with severe postoperative pain and/or swelling were classified as flare-ups.
Detailed description
110 teeth with a diagnosis of pulp necrosis and apical radiolucency at the apex. Working length was established with EAL and confirmed radiographically. M4 system with Flex-R files were used to complete canal preparation. Level of discomfort were recorded and cases with severe postoperative pain and/or swelling were classified as flare-ups.
Interventions
PROCEDUREIbuprofen for post operative pain
All treatment sessions were approximately 50 minutes in length to allow for acceptable time for completion of treatment and retreatment in one or two visits. All the clinical procedures were performed by the author. Following local anesthesia with 2% lidocaine with 1:100,000 epinephrine (Septodont Saint-Maur des Fossés, France) and rubber dam isolation the tooth was disinfected with 5.25% NaOCl (Ultra bleach, Bentonville, AR, USA).
DRUGAcetaminophen 325 mg for Flare up
Each patient will be evaluated a week after completion the clinical procedures.

Inclusion criteria
* a) Radiographic evidence of apical periodontitis (minimum size ≥2.0 mm x 2.0 mm) and a diagnosis of pulpal necrosis confirmed by negative response to hot and cold tests and b) Need for retreatment. Thermal pulp testing was performed by the author, and radiographic interpretation was verified by one certified oral surgeon.
Exclusion criteria
* patients without inclusion requirements or failure to obtain patient´s authorization. Patients, were excluded if they were younger than 18 years old, pregnant, had a positive history of antibiotic use within the past month, suffered from diabetes, or other systemic diseases. Teeth with periodontal pockets deeper than 4 mm also were excluded of the study.
