OBJECTIVE: To compare the frequency of pain in root canal treatment using sodium hypochlorite and chlorhexidine as root canal irrigants. METHODS: The cross-sectional study was carried out from January to June 2016 at the Pakistan Institute of Medical Sciences (PIMS), Islamabad, Pakistan, and comprised patients aged 18-40 years with irreversible pulpitis involving a posterior tooth. The patients were divided into two equal groups, with Group-I receiving 2% chlorhexidine, and Group-II receiving 5.25% sodium hypochlorite. Following the use of the irrigants, the selected teeth were evaluated for pain at 72 hours using Visual Analogue Scale. RESULTS: There were 60 patients divided into groups of 30(50%) each. The overall mean age was 27.97±5.9 years. There were 32 (53.3%) females and 28 (46.6%) males. The mean post-operative pain score was 1.70±1.9 in Group-I and 1.90 ± 2.3 in Group-II (p=0.5). In Group-I, 25(83.3%) patients had no pain while in Group-II, 20(66.7%) had no pain (p=0.1). CONCLUSIONS: There was no difference in post-operative pain at 72 hours between 2% chlorhexidine and 5.25% sodium hypochlorite when used as irrigants.
