Randomized Controlled Trial Comparative Study
Comparing anesthetic efficacy of articaine versus lidocaine as a supplemental buccal infiltration of the mandibular first molar after an inferior alveolar nerve block.
The authors conducted a prospective, randomized, double-blind, crossover study comparing the degree of pulpal anesthesia achieved by means of mandibular first molar buccal infiltrations of two anesthetic solutions: 4 percent articaine with 1:100,000 epinephrine and 2 percent lidocaine with 1:100,000 epinephrine after an inferior alveolar nerve (IAN) block with the use of 4 percent articaine with 1:100,000 epinephrine. ⋯ For a mandibular buccal infiltration of the first molar after a standard IAN block, 4 percent articaine with 1:100,000 epinephrine resulted in a higher success rate (88 percent) than did 2 percent lidocaine with 1:100,000 epinephrine (71 percent success rate).
