ABSTRACT
The purpose of this prospective, randomized, double-blind crossover study was to evaluate the anesthetic efficacy of 2% lidocaine with 1100,000 epinephrine, 4% prilocaine with 1200,000 epinephrine, and 4% prilocaine in maxillary lateral incisors and first molars. Sixty subjects randomly received, in a double-blind manner, maxillary lateral incisor and first molar infiltrations of 1.8 mL of 2% lidocaine with 1100,000 epinephrine, 1.8 mL of 4% prilocaine with 1200,000 epinephrine, and 1.8 mL of 4% prilocaine, at 3 separate appointments spaced at least 1 week apart. The teeth were pulp-tested in 3-minute cycles for a total of 60 minutes. Anesthetic success (ie, obtaining 2 consecutive 80 readings with the electric pulp tester) and onset of pulpal anesthesia were not significantly different between 2% lidocaine with 1100,000 epinephrine, 4% prilocaine with 1200,000 epinephrine, and 4% prilocaine for the lateral incisor and first molar. For both lateral incisor and first molar, 4% prilocaine with 1200,000 epinephrine and 2% lidocaine with 1100,000 epinephrine were equivalent for incidence of pulpal anesthesia. However, neither anesthetic agent provided an hour of pulpal anesthesia. For both lateral incisor and first molar, 4% prilocaine provided a significantly shorter duration of pulpal anesthesia compared with 2% lidocaine with 1100,000 epinephrine and 4% prilocaine with 1200,000 epinephrine.
