Abstract

BACKGROUND

The purpose of this randomized, cross-over trial was to determine if a preoperative dose of dexamethasone administered submucosally is as effective as intravenous (IV) dexamethasone in reducing pain, swelling, and analgesic consumption after periodontal flap surgery.

METHODS

Thirty-nine patients planned for two similar flap surgeries under IV sedation were included. Before the first surgery, patients were randomized to receive 8 mg of IV or submucosal dexamethasone. Via the alternate route, 0.9% sodium chloride (placebo) was administered. Dexamethasone was administered via the opposite route during the second surgery. A standardized regimen of 600 mg ibuprofen and 325 mg acetaminophen was used to manage postoperative pain. Patients recorded pain and swelling levels on a 21-point numerical rating scale (NRS-21) and a four-point visual rating scale (VRS-4), as well as analgesic usage via a phone application at 12, 24, 48, 72, and 168 h postoperatively.

RESULTS

While NRS-21 and VRS-4 data suggest a trend toward decreased pain and swelling with IV administration, there were no significant differences in analgesic usage or pain at any time and a significant difference in swelling only at 72 h in favor of IV administration (p = 0.047).

CONCLUSIONS

There was no significant difference in pain or analgesic usage following periodontal flap surgery comparing IV and submucosal dexamethasone. A statistically significant difference in swelling between groups at 72 h is likely of limited clinical relevance. Submucosal dexamethasone is an effective way to mitigate pain following periodontal surgery, particularly when IV access for sedation is not required.
