ABSTRACT Background: Pain management during and after root canal treatment is a major challenge for dental practitioners. The present study was conducted to compare bupivacaine vs lignocaine in single sitting endodontic treatment. Materials & Methods: The present study was conducted on 60 patients who underwent single sitting root canal treatment of both genders. Patients were divided into 2 groups of 30 each. In group I, 2% lignocaine was administered and in group II, 0.5% bupivacaine was administered followed by single sitting root canal treatment. The pain in both groups was compared using the visual analogue scale (VAS) before treatment and 3, 6, 12 and 24 hours after treatment. Results: The mean VAS before treatment in both group I was 76, at 3 hours was 4.6 in group I and 4.0 in group II, at 6 hours was 4.0 in group I and 3.4 in group II, at 12 hours was 3.2 in group I and 2.1 in group II, at 24 hours was 2.2 in group I and 1.5 in group II. The difference was significant (P< 0.05). Conclusion: Single sitting root canal treatment, bupivacaine found to be superior in controlling pain as compared to lignocaine.
