IntroductionAchieving pulp anesthesia with irreversible pulpitis is difficult. This study evaluated whether nonsteroidal anti-inflammatory drugs assist local anesthesia.MethodsIn a randomized double-blinded clinical trial, 150 patients (50 per group) with irreversible pulpitis were given placebo, 600 mg ibuprofen, or 75mg indomethacin 1 hour before local anesthesia. Each patient recorded their pain score on a visual analog scale before taking the medication, 15 minutes after anesthesia in response to a cold test, during access cavity preparation and during root canal instrumentation. No or mild pain at any stage was considered a success. Data were analyzed by the chi-square and analysis of variance tests.ResultsOverall success rates for placebo, ibuprofen, and indomethacin were 32%, 78%, and 62%, respectively (p < 0.001). Ibuprofen and indomethacin were significantly better than placebo (p < 0.01). There was no difference between ibuprofen and indomethacin (p = 0.24).ConclusionsPremedication with ibuprofen and indomethacin significantly increased the success rates of inferior alveolar nerve block anesthesia for teeth with irreversible pulpitis.
