What is the best local anesthetic for intraoral regional analgesia?
Untitled Document
“The local anesthetic of choice for intraoral regional anesthetic blocks is bupivacaine hydrochloride because of its prolonged duration of action. Although bupivacaine has a six- to 12-minute lag until the onset of analgesia, the analgesia will last four to six hours.”
