IRCT20150924024167N2 IRCT 2020-03-07 Islamic Azad university of medical science, school of dentistry Comparing of effectiveness of two anesthetic techniques on inferior alveolar nerve block Comparison of the effectiveness between conventional and modified inferior alveolar nerve block techniques 2017-09-23 anticipated 37 Complete https://irct.ir/trial/45683 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: The study is performed using the split-mouth method (each side of the mandible as a group) and with the coin method, the starting position (left or right) will be selected for every patient; then each patient, without knowing which numbers correspond to any of the methods, chooses between 1 and 2 numbers in different envelopes (2 as modified and 1 as conventional) to get started, Blinding description: Patients are unaware of the type of anesthesia and side of mandible, which will be performed first. N/A Indication of posterior teeth anesthesia in the form of bilateral. Intervention 1: Intervention group: as modified technique, a 1.8 cc Lidocaine 2% anesthetic solution with 1.80000 epinephrine is used. The syringe body is placed on the occlusal of the first molar on the opposite side, and needle enters perpendicular to the medial mandibular ramus just lateral to the pterygomandibular fold and needle enters on 10 mm or so above the occlusal plane and parallel to it. The techniques will be considered successful if the lip and tongue is anesthetized after 5 minutes and if did not happen for another 5 minutes the injection will be repeated one time more. Intervention 2: Control group: as conventional method, a 1.8 cc Lidocaine 2% anesthetic solution with 1.80000 epinephrine is used. The syringe body is placed on the opposite premolars and needle enters ¾ anterior posterior distance from Coronoid process to pterygomandibular raphe and with the line that is perpendicular to it from the tuberosity, and needle enters on 10 mm or so above the occlusal plane and parallel to it. The techniques will be considered successful if the lip and tongue is anesthetized after 5 minutes and if did not happen for another 5 minutes the injection will be repeated one time more. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is to consider publishing a paper
