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.
