The purpose of this study was to compare the anesthetic efficacy of articaine, lidocaine and mepivacaine in patients with irreversible pulpitis of mandibular molar.
Conventional inferior alveolar nerve block (IANB) is the most commonly used technique for achieving pulpal anesthesia in posterior mandibular endodontic procedures. However, IANB has a high failure rate and success rates are even lower when applied for the treatment of mandibular posterior teeth with irreversible pulpitis.

-22 patients received inferior alveolar nerve block injections of 3.6 mL (equivalent to 2 cartridges)
Emergency Center of the School of Dentistry at the University of São Paulo
São Paulo, São Paulo, Brazil
pulpal anesthesia
pulpal anesthesia was tested with an electric pulp stimulator
Time frame: Ten minutes after the inferior alveolar nerve block
analgesia
To evaluate the intensity of pain during the pulpectomy a verbal analogic scale was adopted
Time frame: the patients were instructed to report any painful sensation at three phases: 1) dentin 2) pulp chamber 3) root canal
