The Efficacy of Different Anesthetic Techniques as Primary Injection in Mandibular Molars with Irreversible Pulpitis (In vivo Study)

Abstract

The aim of this study was to compare the ability of different anesthetic techniques to control the pain during coronal access preparation when used as primary injections in mandibular molars with irreversible pulpitis. Seventy five healthy patients who needed endodontic treatment voluntarily participated in this study and were randomly allocated to the different groups. Patients were randomly assigned into 5 groups, each group had 15 patients; Group 1: received traditional inferior alveolar nerve block (IANB). Group 2: received intraosseous anesthesia (IO). Group 3: received intraligamentary (periodontal ligament PDL) anesthesia. Group 4: received traditional IANB followed by IO injection. Group 5: received traditional IANB followed by PDL injection. The previous injections were administered once, just before the coronal access preparation. The efficacy of anesthesia was determined by using electric pulp tester and pain scale. The results obtained showed that there was no statistical significant difference between the anesthetic techniques which were tested in this study.
