Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To achieve painless treatment in patients with a failed primary IANB, supplementary anesthesia has been advised. The majority of the studies evaluating intrapulpal injections have been performed on asymptomatic teeth. Very limited research has been dedicated to the evaluation of different variables in intrapulpal injections in patients with symptomatic irreversible pulpitis. The aim of this study was to evaluate postoperative pain after an intrapulpal anesthesia injection given after a failed inferior alveolar nerve block (IANB), in patients with symptomatic irreversible pulpitis. This prospective, randomized, double-blind clinical trial was carried out at the Department of Conservative Dentistry and Endodontics, Faculty of Dentistry, Jamia Millia Islamia. One hundred and eight adult patients, with symptomatic irreversible pulpits in a mandibular first or second molar received an initial IANB with 2% lidocaine. Pain during the endodontic treatment was assessed using a visual analog scale (VAS). Patients experiencing pain on endodontic intervention were randomly allocated to one of the two treatment groups: one group received a supplementary intrapulpal injection while the other received a supplementary intraligamentary injection The presence of postoperative pain was assessed at 1, 2, 3, and 7 days after treatment.
