Buccal Block

In anesthesia for a buccal block, the use of 4% articaine with 100,000 epinephrine should be the drug of choice.¹⁹ A study by Srinivasan et al²² reported that the efficacy of 4% articaine with 100,000 epinephrine was superior to 2% lidocaine with 100,000 epinephrine for buccal infiltrations in maxillary posterior teeth. Another study, by Brandt et al,¹⁸ demonstrated better pulpal anesthesia with articaine versus lidocaine when using it as an infiltration local anesthesia.
