INTRODUCTION: Studies have shown the superiority of 4% articaine with 1:100,000 epinephrine over 2% lidocaine with 1:100,000 epinephrine when used as a primary buccal infiltration of the mandibular first molar. A study using other 4% anesthetic formulations may help determine the role of concentration in the increased efficacy of 4% articaine. The authors conducted a prospective randomized, double-blind, crossover study comparing the pulpal anesthesia obtained with 4% concentrations of articaine, lidocaine, and prilocaine formulations as primary buccal infiltrations of the mandibular first molar.
METHODS: Sixty asymptomatic adult subjects randomly received a primary mandibular buccal first molar infiltration of 1.8 mL 4% articaine with 1:100,000 epinephrine, 4% lidocaine with 1:100,000 epinephrine, and 4% prilocaine with 1:200,000 epinephrine in 3 separate appointments. An electric pulp tester was used to test the first molar for anesthesia in 3-minute cycles for 60 minutes after the infiltrations. Successful anesthesia was defined as 2 consecutive 80/80 readings.
RESULTS: The success rate for the 4% articaine formulation was 55%, 33% for the 4% lidocaine formulation, and 32% for the 4% prilocaine formulation. There was a significant difference between articaine and both lidocaine (P = .0071) and prilocaine (P = .0187) formulations.
CONCLUSIONS: A 4% articaine formulation was statistically better than both 4% lidocaine and 4% prilocaine formulations for buccal infiltration of the mandibular first molar in asymptomatic mandibular first molars. However, the success rate of 55% is not high enough to support its use as a primary buccal infiltration technique in the mandibular first molar.
