Evaluation of the impact of Laser application on postoperative pain and healing of the donor area of Gingival Graft: randomized clinical trial

INTERVENTION: E02.594.540 Low intensity laser will be applied in half of the sample (n=8), test group and the placebo laser in another half (n=8), control group. The laser used will be the Laser Duo MMOptics, which will be applied for 20 seconds punctually throughout the graft donor area and on the graft, post‐surgical, 1.2.3 days after surgery, with a power of 100 mW and a wavelength of 660 nm, totaling 2 joules of energy. The placebo laser will be made through a layer of acrylic resin placed on the tip of the device, which will prevent the passage of photons. CONDITION: G16.762.891 Surgery, Oral PRIMARY OUTCOME: Postoperative pain, determined through the pain scale (0‐10), in the first seven days after surgery. Pain reduction is expected in the test group. SECONDARY OUTCOME: Bleeding ‐ Clinical evaluation at 1,2,3,4 days after surgery. Decreased bleeding is expected in the test group. Edema‐ Clinical evaluation at 1,2,3,4 days after surgery. Decrease in edema is expected in the test group. Evaluation of epithelialization ‐ Test with hydrogen peroxide at 4, 7 and 14 days after surgery. Faster epithelialization is expected in the test group. ; ; ; ; INCLUSION CRITERIA: Patients over 18 years; periodontal health; to sign of the Declaration of Consent; to present from sites with bleeding to approval of less than 10%.
