Aim: To compare the effects of different concentrations of NaOCl and chlorhexidine solution on postoperative pain following single-visit root canal treatment. Methodology: A total of 123 patients who had teeth with irreversible pulpitis were treated. The patients were randomly divided into three groups according to the concentration of NaOCl used and chlorhexidine. Postoperative pain was evaluated using the visual analogue scale. Data were analyzed by independent t-test, chi-square and Mann–Whitney tests. Results: Pain reported by 123 patients who were eligible to be included in the study was analyzed. No significant differences were found in the age and gender of the patients between the two groups (P = 0.50, P = 0.51, respectively). The patients who had 5.25% NaOCl reported significantly lower postoperative pain compared to those who had 2.5% NaOCl during the first 72 h following treatment. Conclusion: 5.25% NaOCl was associated with significantly lower postoperative pain compared to 2.5% NaOCl during the first 72 h following one-visit root canal treatment of teeth with irreversible pulpitis.
