Objective: To compare the anesthetic efficacy of 2% Lidocaine with 1: 80,000 epinephrine and 0.5% Bupivacaine with 1: 200,000 epinephrine in one-visit root canal treatment in patients with symptomatic irreversible pulpitis.
Methods: A total of 60 patients presenting with symptomatic irreversible pulpitis with normal periapical tissues on periapical radiography of mandibular 1st and 2nd molars, reporting moderate to severe pain as assessed by visual analogue scale (VAS) for at least 24 hours were included in this study. All patients received local anesthesia via the inferior alveolar nerve block technique by the investigator. These patients were randomly allocated into two groups in which first group received 2% lidocaine with 1: 80,000 epinephrine and the second group received 0.5% bupivacaine with 1: 200,000 epinephrine. Patients were instructed to rate the intensity of pain during root canal treatment which was then noted on visual analogue scale (VAS).
Results: The average age of the patients was 34.15±9.49 years, in which 32 (53.3%) were male and 28 (46.7%) were female. The anesthetic efficacy was significantly high in bupivacaine as compared to lidocaine local anesthesia group (76.7% versus 40%; P=0.004).
Conclusion: The administration of bupivacaine anesthetic agent for inferior alveolar nerve block (IANB) injections can be a better and appropriate pain management aid as compared to lidocaine during root canal treatment of patient with symptomatic irreversible pulpitis. (EEJ-2019-12-125)
