Summary

<b>Aim:</b> To compare the levels of postoperative pain after cleaning and shaping of root canals using two different root canal irrigants for debridement. <b>Materials and Methods:</b> Forty patients with irreversible pulpitis, pulp necrosis and non-vital teeth exhibiting acute apical periodontitis requiring root canal treatment were included. At random, canals were cleaned and shaped with the following protocols. 2&#x0025; chlorhexidine solution in group I and 5.25&#x0025; sodium hypochlorite solution in group II were used as an irrigants. Access cavities were closed with a sterile cotton pellet and cavit. The patients recorded degree of pain at various time intervals after cleaning and shaping on a visual analogue scale for 1 week. <b>Results:</b> The mean pain score for group I was between 0.65 and 3.35 and for group II was between 0.95 and 4.50. There was significant difference in the pain level between the two groups only at 6 ^th hour postoperatively (<i>P</i>&lt;0.05) and the pain was more in sodium hypochlorite group. <b>Conclusions:</b> More pain was present in teeth irrigated using 5.25&#x0025; sodium hypochlorite when compared to that in teeth irrigated using 2&#x0025; chlorhexidine solution. Significant difference in pain level was present only at 6th hour postoperatively, and at all other periods (24 ^th hour, 4 ^th and 7 ^th days) there was no significant difference in pain level between the two groups.
