Randomized Controlled TrialAnesthetic efficacy of articaine and lidocaine for incisive/mental nerve block.
The incisive/mental nerve block (IMNB) could be an alternative to the inferior alveolar nerve block in the mandibular anterior teeth. The effectiveness of articaine has not been tested in IMNB. ⋯ Articaine promoted higher anesthesia success and longer duration of anesthesia than lidocaine for most of the teeth after IMNB although anesthesia success could be considered clinically appropriated only for premolars. The volume of local anesthetic used in the present study may not be appropriate for procedures lasting longer than 10 minutes.

Randomized Controlled Trial Comparative StudyComparative evaluation of effect of preoperative oral medication of ibuprofen and ketorolac on anesthetic efficacy of inferior alveolar nerve block with lidocaine in patients with irreversible pulpitis: a prospective, double-blind, randomized clinical trial.
Anesthetic efficacy of inferior alveolar nerve block decreases in patients with irreversible pulpitis. It was hypothesized that premedication with nonsteroidal anti-inflammatory drugs might improve the success rates in patients with inflamed pulps. ⋯ Preoperative administration of ibuprofen or ketorolac has no significant effect on success rate of inferior alveolar nerve block in patients with irreversible pulpitis.

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.
