The aim of this randomized, double-blinded, clinical trial was to assess the effect of 3.6 mL 2% mepivacaine hydrochloride with 1:100,000 epinephrine compared to 3.4 mL 4% articaine hydrochloride with 1:100,000 epinephrine on the success of the inferior alveolar nerve block for patients with symptomatic irreversible pulpitis in mandibular molars. Patients were clinically and radiographically examined and their eligibility assessed and preoperative pain was measured using the numerical rating scale (NRS). Patients were randomly assigned to one of 2 groups: experimental group (2% mepivacaine) and the control group (4% articaine). After 15 minutes of the inferior alveolar nerve block (IANB), patients reporting lip numbness had their molars accessed. No-to-mild pain response was considered success during root canal preparation.
