Summary
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 opposite side), and after the aspiration of the
contents of each cartridge in a 1 minute period It is injected. After 15 minutes, in case of
numbness of the lips, the patient begins to study and the access cavity begins on the desired
tooth. In each of the stages of acquiring the access cavity or entering the initial file to
the canal, in the event of pain, the treatment is suspended and the patient signs his pain on
the pain assessment chart based on the Heft-parker VAS and at this stage the study It's over.
In the absence of anesthetized lips, the patient is excluded from the study and after
completing the injection, the root canal is given.
