Objective: Single file systems with continuous rotation or reciprocation produced with many new technologies promising in terms of postoperative pain. The aim of this study was to investigate the efficacy of using novel Reciproc Blue (RBlue) and HyFlex EDM (HEDM) files on postoperative pain after single visit root canal treatment. Materials and Methods: 72 patients with asymptomatic pulp necrosis in mandibular molar and premolar teeth were included. The root canals were prepared using HEDM (n=29) or RBlue (n=28) and hand-instruments (n=15) in single visit. Pain presence using verbal rating scale (VRS) and analgesic intake were recorded after 24h, 48h, 72h and 7 days. Results: Postoperative pain at 24h and 48h was statistically higher at RBlue group than HEDM and control groups (p0.05).There was no difference between groups in terms of analgesic intake (p>0.05). RBlue files were associated with higher incidence of postoperative pain and higher VRS scores than HEDM and hand-instruments. Conclusion: RBlue files working with reciprocating motion caused much more postoperative pain than HEDM files and manual files.
