Possible participants will be scheduled to have 2 gum flap surgeries done on 2 similar surgical sites in the mouth. The study looks at two different ways of giving dexamethasone, a medication used to reduce inflammation. The researchers want to learn if taking dexamethasone by mouth works similarly to receiving dexamethasone through the participant's vein (intravenous, or IV) in reducing short-term pain, swelling, and pain medication after periodontal (gum) flap surgery. The periodontal evaluation, treatment planning, IV sedation, gum surgery, sutures, and usual postoperative care are part of standard care and would be done even if a participant does not join the study. After joining the study, participants will be randomly assigned to the order in which they receive dexamethasone. At one surgery, participants will receive IV dexamethasone plus oral placebo (an inactive substance that looks the same but does not contain dexamethasone). At the next surgery, participants will receive oral dexamethasone plus IV placebo. As part of the study, participants will be asked to record your pain, swelling and any other medication use.
There will be two randomized treatment sequences and two study intervention conditions: intravenous dexamethasone with oral placebo, and oral dexamethasone with intravenous placebo. Each participant will receive both intervention conditions and will serve as his or her own control. This cross-over design was selected to reduce between-participant variability in pain perception, inflammatory response, medication use, and healing patterns. The matched placebo blinding approach was selected to preserve blinding while allowing comparison of two different routes of administration. The study intervention consists of a single preoperative dose of dexamethasone administered either intravenously or orally prior to each periodontal flap surgery. Placebo will be administered by the alternate route at each surgical visit to maintain blinding. The intervention duration for each surgical visit is limited to the single preoperative dosing event. Follow-up outcome assessments will occur at 12, 24, 48 and 72 hours after each periodontal surgery. No separate placebo-only or no-treatment control group will be used because the primary study question is whether oral dexamethasone provides comparable short-term patient-centered outcomes to intravenous dexamethasone. Prior periodontal studies have already evaluated dexamethasone compared with placebo or control therapy. In this design, each participant serves as his or her own control by receiving dexamethasone through both routes during two similar surgical procedures.

21-point numerical pain rating scale (NRS-21)
Change in pain on NRS-21, a 21 item scale that is scored using a numeric scale where patients choose from 0-20: 0: No pain at all 1 - 6: Mild pain (noticeable but doesn't disrupt activities) 7 - 13: Moderate pain (interferes significantly with focus, tasks, or sleep) 14 - 20: Severe / Worst imaginable pain (debilitating, unbearable)
Time frame: 12 to 72 hours post surgery
Pain assessment using Verbal Rating Scale (VRS-4)
A rating scale used to assess pain by score rated from 0-3 where; 0 = None (No pain) 1. = Mild 2. = Moderate 3. = Severe
Time frame: 12 to 72 hours post surgery
Patient reported Postoperative swelling using NRS-21
The scale uses integers or half-integers from 0-10 spread across 21 distinct points: 0 represents no swelling. 10 represents the worst or most severe swelling imaginable.
Time frame: 12-72 hours post surgery
Swelling rating using VRS-4
The 4-point pitting edema scale grades swelling depth and how long the skin takes to rebound after pressure graded from 1-4: Grade 1+ (Trace/Mild): Depth of 2 mm; skin rebounds immediately. Grade 2+ (Mild/Moderate): Depth of 3 to 4 mm; skin rebounds in less than 15 seconds. Grade 3+ (Moderate): Depth of 5 to 6 mm; skin takes 10 to 30 seconds (or longer) to rebound. Grade 4+ (Severe): Depth greater than 8 mm; skin takes more than 20 to 30 seconds (up to a few minutes) to rebound.
Time frame: 12 to 72 hours post surgically
Number of patient reported analgesics post surgery
Patient-reported analgesic consumption, including ibuprofen and acetaminophen use
Time frame: 12 - 72 hours post surgery
