Aim: The purpose of this study was to evaluate the influence of the calcium hydroxide chlorhexidine combination and calcium hydroxide as an intra-canal medicament on postoperative pain and swelling (flare-up) in two visits endodontic retreatment cases with a randomized clinical trial. Methods: Twenty four patients, aged from 20-50 years old with no gender prediction, suffering from failed previous endodontic treatment were included in this study. After confirming the diagnosis clinically and radiographically, patients were randomly assigned into two equal groups of 12 patients each. After removal of the previous root canal filling, root canals were prepared and cleaned with 2.5% sodium hypochlorite, root canals were medicated with calcium hydroxide chlorhexidine combination in the intervention group, whereas the comparator group was medicated with calcium hydroxide as intracanal medicaments for 7 days. Endodontic treatment was completed in the second visits and lateral condensation technique with ADSEAL resin sealer used for obturation. Pain was assessed postoperatively after 6, 12, 24, 48, 72 hours and at 7 days before obturation. Categorical Scale for pain measuring and presence and absence of swelling was used as the primary outcome measure. Patients were given an analgesic (Ibuprofen 200 mg) in case of severe pain. All demographic data and categorical scores were collected from the patients and statistically analyzed
