Details and patient eligibility

About

This study will aim to evaluate postoperative pain after intraligamentary injections of dexamethasone (4mg/ml), diclofenac sodium (25mg/ml), 0.5% bupivacaine and 2% lidocaine given to the patients with symptomatic irreversible pulpitis after completion of the first appointment. Objectives: 1. To evaluate postoperative pain in patients receiving intraligamentary injections of either dexamethasone (4mg/ml), diclofenac sodium (25mg/ml), 0.5% bupivacaine or 2% lidocaine. 2. To compare the postoperative pain in different groups.

Full description

The patients will receive a primary Inferior alveolar nerve block injection using 1.8 mL of 2% lidocaine with 1: 80 000 epinephrine using a direct Halsted approach. The needle will be inserted until bony resistance is felt. After reaching the target area, aspiration will be performed, and the solution will be deposited over 60 seconds. After 10 minutes, the patients will be asked about the lip numbness. Patients without profound lip numbness will be excluded from the study since the block will be considered as 'missed'. A conventional access opening will be initiated after isolation with a rubber dam. After endodontic instrumentation and placement of temporary restoration, the patients shall receive intraligamentary injections of dexamethasone (4mg/ml), diclofenac sodium (25mg/ml), 0.5% bupivacaine, and 2% lidocaine. The patients will be randomly allocated to treatment groups with the help of an online random generator. The presence of postoperative pain (using Heft Parker visual analog pain scale) will be assessed at 2 hours, 6 hours, 24 hours, and 72 hours after treatment. The pain score proforma shall be collected at the subsequent visit.
