Abstract OBJECTIVE: The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of 4\% articaine and 2\% lidocaine (both with 1:100,000 epinephrine) for buccal infiltration in patients experiencing irreversible pulpitis in maxillary posterior teeth. STUDY DESIGN: Forty patients with irreversible pulpitis in first premolar or first molar were divided into 4 study groups and received buccal infiltration of either 4\% articaine or 2\% lidocaine in a double-blind manner. Endodontic access was begun 5 minutes after solution deposition. Success was defined as no or mild discomfort (VAS recordings) during the endodontic procedure. RESULTS: The success rate for maxillary buccal infiltration to produce pulpal anesthesia using articaine was 100\% in first premolar and first molar, and for the lidocaine solution, success rate was 80\% in first premolar and 30\% in first molar. There was high significant difference between the articaine and lidocaine solutions (ANOVA; P < .001). CONCLUSION: The efficacy of 4\% articaine was superior to 2\% lidocaine for maxillary buccal infiltration in posterior teeth.
