Abstract INTRODUCTION: The study was designed as a randomized double-blind trial to evaluate the anesthetic efficacy of 4\% articaine with 1:100,000 epinephrine in inferior alveolar nerve block (IANB) and infiltration anesthetic techniques to anesthetize mandibular molars with irreversible pulpitis. METHODS: The study was composed of 2 test arms and 1 control arm. Subjects in the test arms received either a standard IANB or a buccal infiltration (B Infil) of 4\% articaine with 1:100,000 epinephrine, whereas the subjects in the control arm received a standard IANB of 2\% lidocaine with 1:100,000 epinephrine. Subject's self-reported pain response was recorded on Heft Parker Visual Analogue Scale after local anesthetic administration during access preparation and pulp extirpation. RESULTS: For statistical analysis Pearson χ(2), Student's paired t test, 1-way analysis of variance, and Friedman tests showed no significant difference in success rates among the 3 arms of the trial. CONCLUSIONS: Although B Infil and IANB of 4\% articaine were equally effective, B Infil can be considered a viable alterative in IANB for pulpal anesthesia in mandibular molars with irreversible pulpitis.
