A total of 60 patients presenting with single-rooted teeth exhibiting symptomatic apical periodontitis were subjected to a randomized allocation into two groups of 30 each. Irrigation was done using 3% sodium hypochlorite for 5 seconds in all 60 teeth. Group 1 underwent final irrigation utilizing normal saline at room temperature. Group 2 received final irrigation using normal saline refrigerated between 2-5°C. Pain levels were assessed and recorded before the procedure and at 24 and 48-hour time intervals.
