The effects of 2 % lidocaine with epinephrine 1/80000, 3 %propitocaine with felypressin 0.03IU/ml, 1.5 % etidocaine with epinephrine 1/200000, and 2 % lidocaine without epinephrine, when used for oral infiltration anesthesia, were studied. Ten healthy male volunteers, ranging in age from 20.5 to 34.9 years (mean±SD, 26.7±4.3 years), took part in the study. A volume of 0.5 ml of the respective anesthetic solution was deposited supraperiosteally in the apical area of the maxillary medial incisor. The intensity of 80 was regarded as complete analgesia, and 30 as relative analgesia, and frequency and duration of analgesias were investigated, along the pain threshold value, with the electric pulp stimulator. As a result, etidocaine was shown to have almost the same analgesic effect as propitocaine, but weaker than lidocaine with epinephrine, when applied for oral infiltration anesthesia.
