Dexamethasone Treatment for Patients Undergoing Endodontics

This Phase IV randomized clinical trial (RCT) evaluated the efficacy of preoperative administration of a single 4 mg oral dose of dexamethasone in reducing postoperative pain and inflammation following endodontic treatment. Conducted at the Department of Endodontics, PhD Program, Faculty of Dentistry, University of Salamanca, the study included 82 participants who were randomly assigned to either the test group (preoperative dexamethasone) or the control group (postoperative ibuprofen 400 mg every 4 hours). Pain intensity was measured using the Visual Analog Scale (VAS) at 4, 6, 8, 12, and 24 hours postoperatively. Results indicated significantly lower pain perception in the dexamethasone group compared to the ibuprofen group at all time points, with the majority of dexamethasone-treated patients reporting only mild pain. No adverse effects were observed in either group, and no patient required additional rescue analgesia. The findings suggest that a single preoperative dose of dexamethasone is a safe and effective strategy for managing postoperative pain in endodontic procedures, providing superior analgesia compared to the standard postoperative ibuprofen regimen.
