Effect of Lidocaine With Magnesium Sulfate on the Success of the Inferior Alveolar Nerve Block

68 healthy patients pulpitis and requiring root canal therapy are selected. . Sampling was done in a simple and non-experimental way from a dental clinic in Isfahan, and then the samples were randomly assigned to one of the two experimental groups (A, B) using simple random numbers. Each vial is filled with distilled water or magnesium sulfate by an individual who is unaware of the nature of the design and is not involved in the design, and each letter A or B is written. This statement is not decoded after the statistical examination. Therefore, the study is blind and blind. In this way, 60 patients are examined in 2 groups of 34 First, patients with recognized pulpitis in mandibular posterior teeth have been identified and information about them is given. Patients will be introduced to the executive phase after the required explanation and clarification of the ambiguity and written consent. After completing the patient information form by the practitioner and complying with all entry and exit criteria, the study begins on each patient. The patient records his pain as an initial pain on the Heath-Parker Visual Analogue Scale (VAS). This pain measurement method involves a 180 mm line with descriptive words that differentiates patients on a line where the best describes their pain. In order to design a standard injection of the maxillary nerve block in all patients, using Aspirating Dental Injection Syringe, Novocol Ontario, Canada, the needle of the 27 mm long 35 mm (Septoject, Septodont, Saint-Maur-des- Fosses cedex, France) Lidocaine 2% with epinephrine 80000/1 mixed with magnesium sulfate or distilled water, injections in the retro-cell region and cm1 above the occlusal mandibular plan. After insertion of the needle at a rate of 3-5 mm into the tissue, aspiration was performed and about 2-3 ml / 2. It is injected from the contents of the cartridge, the syringe 1 mm is returned to the bone hard tissue (in the form of the syringe body in the perimmel area of the o
