Advantages of long-acting local anesthesia using etidocaine hydrochloride

Abstract

A double-blind clinical evaluation comparing 1% etidocaine with 1/200,000 epinephrine and 2% lidocaine with 1/100,000 epinephrine for third molar surgery was done on 42 patients. Aspects of long-acting and short-acting local anesthesia were compared, including time of onset, potency, regression, duration, and appraisal by the patient. The preference of patients and the experience of postoperative pain are emphasized.
