IRCT20201129049528N1 IRCT 2020-12-27 Yazd University of Medical Sciences Comparison of success of inferior alveolar nerve block in irreversible pulpitis teeth in supine and upright positions: A clinical study Comparison of success of inferior alveolar nerve block in irreversible pulpitis teeth in supine and upright positions: A clinical study 2020-12-03 anticipated 60 Complete https://irct.ir/trial/52668 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: The samples will be selected from the qualified statistical population using simple sampling or convenient sampling method. Then, the samples will be assigned into the two intervention and control groups randomly; In so doing, 60 questionnaires will be prepared and labeled as A (30 questionnaires) and B (30 questionnaires); then, at the place of intervention, we will want the patient or his or her companion to choose one of them while he or she is blind about the type of treatment or group (blindness). Finally, we will have 30 patients in each group who are selected randomly, Blinding description: Blinding will be performed on patients. N/A Inferior alveolar nerve block. Intervention 1: First Intervention Group: Upright Group: In this study, there are two groups of patients who will go to Yazd dental centers for the treatment of mandibular root canal for whom the diagnosis of irreversible pulpitis has been made. In one group of anesthesia, the inferior alveolar nerve block (IAN) will be injected by upright method and in the second group, this anesthesia will be performed by supine method. The choice of injection for these two groups will be random. The injection will be done with two carpules of 2% lidocaine with epinephrine 1/80000 (Iran Pharmaceutical Company). In the upright method, dental chair headrest has a 75-degree angle with the ground and the occlusal plane of the mandibular teeth is parallel to the ground, and during this injection, the practitioner will stand. The success of IAN block will be compared to measuring the numbness of the corner of the lip within 15 minutes after injection. The presence or absence of pain during the preparation of the access cavity will also be compared. Intervention 2: Second Intervention Group: Supine Group: In this study, there are two groups of patients who will go to Yazd dental centers for the treatment of mandibular root canal for whom the diagnosis of irreversible pulpitis has been Established. In one anesthesia group, the inferior alveolar nerve block (IAN) will be injected using the upright method and in the second group, the anesthetic will be injected using the supine method. The choice of injection for these two groups will be random. The injection will be done with two carpules of 2% lidocaine with epinephrine 1/80000 (Iran Pharmaceutical Company). In the supine group, the headrest of dental chair is lowered so that the patient's foot is a bit above the head and the patient's body is parallel to the floor. The practitioner will sit during this injection. The success of IAN block will be compared to measuring the numbness of the corner of the lip within 15 minutes after injection. The presence or absence of pain during the preparation of the access cavity will also be compared.
