| Popis: | Objective The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of the intraligamentary injection of 4% articaine with 1:100,000 epinephrine and of 2% lidocaine with 1:100,000 epinephrine, administered with computer-controlled local anesthetic delivery system, in mandibular posterior teeth. Study design Using a crossover design, intraligamentary injections of 1.4 mL of 4% articaine with 1:100,000 epinephrine and of 1.4 mL of 2% lidocaine with 1:100,000 epinephrine were randomly administered with a computer-controlled local anesthetic delivery system, in a double-blind manner on the mesial and distal aspects of a mandibular first molar, at 2 separate appointments to 51 subjects. A pulp tester was used to test for anesthesia, in 2-minute cycles for 60 minutes, of the mandibular first and second molars and second premolar. Anesthesia was considered successful when 2 consecutive 80 readings (highest output) were obtained within 20 minutes. Results Successful pulpal anesthesia was obtained 86% of the time for the first molar using the articaine solution and 74% of the time using the lidocaine solution. There were no significant differences ( P > .05) between the articaine and lidocaine solutions. The mean onset times of pulpal anesthesia for the first molar were 1.3 minutes with articaine solution and 2.2 minutes with lidocaine solution. Duration of pulpal anesthesia for the first molar was 34 minutes for the articaine solution and 31 minutes for the lidocaine solution. Conclusion The efficacy of 4% articaine with 1:100,000 epinephrine was similar to the efficacy of 2% lidocaine with 1:100,000 epinephrine for intraligamentary injections. |
