Subjects and methods: 54 patients with symptomatic irreversible pulpitis in mandibular premolar teeth were included. After confirming the diagnosis clinically and radiographically, patients were randomly assigned into two equal groups of 27 patients each. In the intervention group, root canals were prepared with Reciproc reciprocating single-file (40/.06), whereas the comparator group was prepared with One Shape rotary system (25/.06 and then finished with 30/.06 and 37/.06). Endodontic treatment was performed in single visit with 2.5% sodium hypochlorite for cleaning and lateral condensation technique with resin sealer for obturation. Pain was assessed pre-operatively, then postoperatively immediately at the end of treatment and after 6, 12, 24, 48 and 72 hours. Numerical Rating Scale (NRS) was used as the primary outcome measure. Patients were given an analgesic (Ibuprofen 200 mg) in case of severe pain. All demographic data and NRS scores were collected from the patients and statistically analyzed ER -
