Effect of intravenous dexamethasone on postoperative pain and swelling following periodontal flap surgery: A randomized controlled trial of patient-centered outcomes.

Background: This randomized, crossover trial sought to determine if a preoperative intravenous (IV) dose of dexamethasone reduces pain, swelling, and analgesic usage following periodontal surgery.

Methods: Thirty-seven patients planned for two similar periodontal flap surgeries under IV sedation were enrolled. Patients were randomized to receive either 2 mL (8 mg) dexamethasone sodium phosphate or 2 mL of IV solution (placebo) before the first surgery, and 2 mL of the other solution before the second surgery.

Dentist-Patient Communication of Treatment Outcomes in Periodontal Practice: A Need for Dental Patient-Reported Outcomes.

Periodontal practice has made tremendous progress toward evidence-based treatment over the past decade. Importantly, a new classification scheme for periodontal and peri-implant treatments has recently been devised that is incorporating current evidence and enabling patient-specific periodontal care. However, this important progress can be further accelerated with the availability of patient-perceived outcomes of periodontal and implant interventions.

Effect of different concentrations of commercially available mouthwashes on wound healing following periodontal surgery: a randomized controlled clinical trial.
