Role of the anesthetic solution in intrapulpal anesthesia

John Birchfield, Paul A. Rosenberg

Research output: Contribution to journalArticlepeer-review


After local infiltration or regional block, 56 patients had inadequate anesthesia for extirpation of the pulp. Adequate anesthesia then was obtained by intrapulpal injection. Sterile normal saline solution was used in 37 instances and lidocaine 2% with epinephrine 1:50,000 in 19 instances. Pressure seems to be the major factor in producing intrapulpal anesthesia.
