Background: The purpose of this prospective, randomized, double-blind, placebo-controlled study was to compare the effect of the administration of preoperative ibuprofen, ketorolac, combination of etodolac with paracetamol and combination of aceclofenac with paracetamol versus placebo for the potential increased effectiveness of the inferior alveolar nerve block [IANB] anesthesia. Materials and Methods: A total of 100 endodontic emergency patients in moderate to severe pain diagnosed with irreversible pulpitis of a mandibular posterior tooth randomly received, in a double-blind manner, either a drug or placebo 30 minutes before the administration of a conventional IANB. Cold testing was done before administration of anesthesia to determine level of pain using Heft-Parker Visual Analogue Scale (VAS) score. Success was defined as no pain or pain (VAS) on access or initial instrumentation. Results: Overall success was 54% for all the groups. Success was highest (70%) for the ketorolac group, 55% for both ibuprofen group and combination of aceclofenac with paracetamol group, 50% for combination of etodolac with paracetamol group, and 40% for the placebo group. Conclusions: Under the conditions of this study, the use of preoperative medication did improve the anesthetic efficacy of IANB for the treatment of teeth diagnosed with irreversible pulpitis but not significantly.
