AIM: To estimate and compare the postoperative pain after root canal treatment using hand and rotary instruments in non- vital teeth. Materials & Methods: A total of 50 patients requiring root canal treatment in non- vital molars were selected and subjected to root canal treatment were divided into Group1. hand instrumentation, Group2 ProTaper rotary instrumentation technique.Patients were instructed to complete a pain diary using a visual analog scale (VAS) at 24 hours, 72 hours and 7 days Statistical Analysis: VAS score 0 was seen in 21 at 24 hours, 23 at 72 hours and 25 at 7 days in group I and 23 at 24 hours, 25 at 72 hours and 25 at 7 days in group II. VAS score 1 was seen in 2 and score 2 in 2 patients in group I at 24 hours, in group II 1 patients each had score 1 and 2 at 24 hours. Conclusion: Compared to hand instrumentation rotary instrumentation had less postoperative pain. Key words: Pain, VAS, Root canal treatment, Rotary instrumentation, Post operative pain.
