Randomized Controlled TrialA prospective, randomized single-blind study of the anesthetic efficacy of the inferior alveolar nerve block administered with a peripheral nerve stimulator.
The purpose of this prospective, randomized single-blind study was to compare the degree of pulpal anesthesia obtained with the inferior alveolar nerve (IAN) block administered by using a peripheral nerve stimulator compared with a conventional IAN block by using a cartridge of 2% lidocaine with 1:100,000 epinephrine. ⋯ We concluded that the IAN block administered with a peripheral nerve stimulator did not increase the success rate of pulpal anesthesia when compared with a conventional IAN block.

Randomized Controlled Trial Comparative StudyA prospective, randomized, double-blind comparison of the anesthetic efficacy of two percent lidocaine with 1:100,000 and 1:50,000 epinephrine and three percent mepivacaine in the intraoral, infraorbital nerve block.
The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of 2% lidocaine with 1:100,000 epinephrine, 2% lidocaine with 1:50,000 epinephrine, and 3% mepivacaine in the intraoral, infraorbital nerve block. ⋯ The intraoral, infraorbital nerve block was ineffective in providing profound pulpal anesthesia of the maxillary central incisor, lateral incisor, and first molar. Successful pulpal anesthesia of the canine and first and second premolars ranged from 75%-92% by using 2% lidocaine with 1:100,000 and 1:50,000 epinephrine. However, pulpal anesthesia did not last for 60 minutes. The use of 3% mepivacaine provided a shorter duration of anesthesia than the lidocaine formulations with epinephrine in the canines and premolars.

Randomized Controlled Trial Comparative StudyA prospective, randomized comparison of the anesthetic efficacy of the greater palatine and high tuberosity second division nerve blocks.
Few clinical studies have evaluated the efficacy of the maxillary second division nerve block. The purpose of this prospective, randomized study was to compare the anesthetic efficacy of the greater palatine second division nerve block and the high tuberosity second division nerve block technique by using 3.6 mL of 2% lidocaine with 1:100,000 epinephrine. ⋯ Both techniques resulted in a high success rate of pulpal anesthesia (95%-100%) for first and second molars. Around 70%-80% of the second premolars were anesthetized with both techniques. Both techniques were ineffective for profound pulpal anesthesia of the anterior teeth and first premolars.

Randomized Controlled TrialA prospective, randomized, double-blind comparison of 2% lidocaine with 1:100,000 and 1:50,000 epinephrine and 3% mepivacaine for maxillary infiltrations.
The purpose of this prospective, randomized, double-blind crossover study was to evaluate the anesthetic efficacy of 2% lidocaine with 1:100,000 and 1:50,000 epinephrine and 3% mepivacaine in maxillary lateral incisors and first molars. ⋯ Anesthetic success and the onset of pulpal anesthesia were not significantly different between 2% lidocaine with either 1:100,000 or 1:50,000 epinephrine and 3% mepivacaine for the lateral incisor and first molar. Increasing the epinephrine concentration from 1:100,000 to 1:50,000 in a 2% lidocaine formulation significantly decreased pulpal anesthesia of short duration for the lateral incisor but not the first molar. For both the lateral incisor and first molar, 3% mepivacaine significantly increased pulpal anesthesia of short duration compared with 2% lidocaine with either 1:100,000 or 1:50,000 epinephrine.

Randomized Controlled TrialAnesthetic efficacy of supplemental buccal and lingual infiltrations of articaine and lidocaine after an inferior alveolar nerve block in patients with irreversible pulpitis.
The success rate of inferior alveolar nerve block (IANB) decreases in patients with irreversible pulpitis. It was hypothesized that supplemental infiltration of lidocaine and articaine may improve the success rates. ⋯ Although supplemental buccal and lingual infiltrations of 4% articaine or 2% lidocaine increased the success rate of the inferior alveolar nerve block in patients with irreversible pulpitis, none of the techniques provided acceptable success rates.
