简要总结
The aim of this prospective randomized double blind trial is to evaluate the anaesthetic efficacy of 4% articaine given as supplementary buccal infiltration after a failed 2% lignocaine which will be given either as inferior alveolar nerve block or Gow Gates nerve block.
114 Patients with symptomatic irreversible pulpitis in mandibular first or second molar will be selected. Patients will be randomly assigned into 2 groups according to the injection method as follows: in group I (n=57) - patients will receive Inferior alveolar nerve block, in group II (n=57) - patients will receive Gow Gates nerve block. 3.6 ml of 2% lignocaine with 1:80,000 epinephrine will be injected according to their assigned groups. After 15 minutes , the success of the anaesthetic technique will be evaluated in their respective groups and endodontic treatment will be initiated. Pain during the endodontic treatment will be assessed using the Heft -Parker Visual analog scale. Patients having inadequate pulpal anaesthesia will receive 0.9 ml of 4% articaine with 1:1,00,000 epinephrine as buccal infiltration. After 10 minutes, endodontic treatment will be reinitiated and pain scores will be recorded.
