Reasons for local anesthesia failures.
Abstract
U.S. dental practitioners administer about 4,000,000 local anesthetic blocks and infiltrations annually. The failure rate to achieve adequate anesthesia for the procedure is estimated to be 5 percent to 15 percent. This article describes five different categories of failures and suggest ways to troubleshoot them.
