Local Dexamethasone Administration in Symptomatic Irreversible Pulpitis

Sponsor: Marmara University

View on ClinicalTrials.gov

Summary

Symptomatic irreversible pulpitis is associated with a high incidence of inadequate pulpal anesthesia during endodontic treatment, particularly in mandibular molar teeth. Failure to achieve profound anesthesia may result in increased intraoperative pain and patient discomfort. Corticosteroids have been suggested as adjunctive agents to improve pain control and reduce inflammatory responses; however, the influence of different local administration techniques on anesthetic success and postoperative pain remains unclear. The aim of this randomized controlled clinical trial is to compare the effects of submucosal and intraligamentary dexamethasone administration on anesthetic success and pain control in patients with symptomatic irreversible pulpitis. A total of 84 participants requiring root canal treatment of mandibular first or second molars diagnosed with symptomatic irreversible pulpitis will be randomly allocated to one of three groups: (1) inferior alveolar nerve block (IANB) followed by submucosal saline injection (control group), (2) IANB followed by submucosal dexamethasone injection, and (3) IANB followed by intraligamentary dexamethasone injection. All participants will receive standardized endodontic treatment under local anesthesia. The primary outcome measure is anesthetic success during access cavity preparation and pulp extirpation. Secondary outcome measures include postoperative pain intensity at 6, 12, 24, 48, and 72 hours, and postoperative analgesic consumption. The results of this study may provide evidence regarding the effectiveness of different local dexamethasone administration techniques and contribute to improved pain management strategies in endodontic practice.
