Aim: This in vivo double-blind randomized control trial was carried out to evaluate the efficacy of a long-acting local anesthetic bupivacaine in preventing postoperative pain associated with single sitting endodontic treatment and to compare it with lignocaine when used as a local anesthetic agent. Methods: A total of fifty patients with symptomatic irreversible pulpitis were selected to be included in the study. The patients were randomly divided into two groups: Group A patients were given lignocaine as local anesthetic and Group B were given bupivacaine. The root canal procedures for the patients were carried out in single sittings under rubber dam using hand ProTaper system, 2.5% sodium hypochlorite as irrigant alternating with normal saline and obturation by lateral condensation technique. A questionnaire employing visual analog scale for pain assessment was given to the patient and instructions on how to fill the form were given. The patients were recalled after 2 days, and the pain was analyzed. The result was tabulated and statistically analyzed for incidence and degree of pain. Results: The mean overall postoperative pain for bupivacaine was lesser than that for lignocaine, and the difference was statistically significant. Conclusion: Based on our findings and in comparison with those of other studies, we reached the conclusion that it may be recommended that bupivacaine may replace lignocaine as the anesthetic of choice in the single visit endodontic protocol in order to reduce the incidence of postoperative pain often seen after single visit endodontic procedures.
