Regional analgesia with bupivacaine in dental anaesthesia

Sixty (ASA 1) patients were studied to determine the effect of bilateral local infiltration with 0.25% bupivacaine plain during third molar extraction under general anaesthesia. Bupivacaine infiltration significantly reduced the incidence of wide complex extrasystoles (P less than 0.05) during surgery and the severity of dental pain (P less than 0.05), when assessed at 6 h after operation.
