Evaluation of etidocaine hydrochloride for local anesthesia and postoperative pain control in oral surgery.

Etidocaine hydrochloride, an amide-type local anesthetic with prolonged duration of action, was evaluated and compared with a standard local anesthetic, lidocaine, to determine its efficacy as a local anesthetic and its effect on postoperative pain following removal of impacted third molars. The findings indicate that 1.5% etidocaine hydrochloride with 1:200,000 epinephrine, in comparison with 2% lidocaine hydrochloride with 1:100,000 epinephrine, suppresses the magnitude of postoperative pain, and results in anesthesia comparable with that obtained by lidocaine, but results in greater blood loss during surgery.
