Abstract
The purpose of this prospective, randomized, double-blind study was to evaluate the anesthetic efficacy of 1.8 mL 0.5% bupivacaine with 1:200,000 epinephrine and 1.8 mL of 2% lidocaine with 1:100,000 epinephrine in maxillary lateral incisors and first molars. Sixty-five subjects randomly received, in a double-blind manner, two infiltrations at two separate appointments, in a crossover design. The injections consisted of maxillary lateral incisor and first molar infiltrations of 1.8 mL 0.5% bupivacaine with 1:200,000 epinephrine and 1.8 mL 2% lidocaine with 1:100,000 epinephrine. In maxillary lateral incisors, bupivacaine exhibited a significantly lower anesthetic success rate (obtaining two consecutive 80 readings with the pulp tester within 10 minutes) of 78% when compared with a 97% success rate with lidocaine. In maxillary first molars, bupivacaine's onset of pulpal anesthesia (7.7 minutes) was significantly slower than lidocaine (4.3 minutes). Bupivacaine had a lower success rate than lidocaine (64% versus 82%) but there was no significant difference between the two solutions. Neither solution provided pulpal anesthesia for 1 hour.
