The Efficacy of Two Anesthetic Techniques as Primary and Supplemental Injection in Teeth With Acute Pulpitis (An in Vivo Study)

Abstract

The discovery of local anesthesia has enabled the modern dentistry to be performed almost painlessly. Although the anesthetic effect can lead to a painless dental procedure, the delivery of local anesthetic solution and the needle puncturing the mucosa can be uncomfortable. There is a constant search for ways to avoid the invasive and often painful nature of the injection, and to find a more pleasant means of producing local anesthesia before and during dental procedures. A computer-controlled local anesthetic delivery system has been developed as a possible solution to reduce the pain related to the local anesthetic injection. The current study was performed to evaluate and compare the efficacy of the Computer-Controlled Local Anesthetic Delivery System (CCLADS) and Conventional Syringe techniques as primary and supplemental injection in teeth with irreversible pulpitis. 40 patients ranging in age between 20 to 40 years were included in this study. All patients have two adjacent teeth with irreversible pulpitis. The patients were divided into two groups according to techniques of anesthesia : _Group 1: Computer-Controlled Local Anesthetic Delivery System (CCLADS) group. Primary injection (An inferior alveolar nerve block or infiltration) and a periodontal ligament injection of local anesthesia will be made using (CCLADS) in a one tooth of patient. _ Group 2: Traditional syringe group. Primary injection (An inferior alveolar nerve block or infiltration) and a periodontal ligament injection of local anesthesia will be made using traditional syringe in the adjacent tooth of the same patient. Each group included 40 teeth. In each group the local anesthesia was administered using the conventional syringe on the first tooth the first appointment. The adjacent tooth anesthetized using the computerized local anesthetic delivery system (STA system) in the second appointment.
