EFFICACY OF LOW-POWER LASER IN FIRST INTENTION HEALING AND POSTOPERATIVE PAIN AFTER CLINICAL CROWN AUGMENTATION SURGERY IN AN AESTHETIC AREA: A RANDOMIZED CLINICAL TRIAL
Low Power Laser; Photobiomodulation; Biostimulation; Dental Aesthetics; gingival smile.
Clinical Crown Augmentation (CCA) surgery is the most commonly performed procedure for the treatment of gingival overgrowth. Healing in these surgeries occurs slowly, which requires, in most cases, the application of adjuvant means that assist in tissue repair. The use of Low-level Laser Therapy (LLLT) has attracted interest in Dentistry due to its photobiomodulatory action being effective in the tissue healing process and reducing postoperative pain. Objective: To evaluate the effectiveness of LLLT photobiomodulation in tissue healing by first intention and postoperative pain after ACC surgery in the aesthetic area with a total flap. Methodology: This is a split-mouth, triple-blind, randomized and controlled clinical trial, in which patients will be divided into two groups: group 1 (G1-control): hemiarch submitted only to surgery; and group 2 (G2-test): hemiarch submitted to laser application after surgery - 4J, 660nm, 100W, applied for 5 minutes in continuous movement throughout the entire length of the surgery. Periodontal parameters of Bleeding on Probing (SS), Probing Depth (PS), Gingival Phenotype (FG), Keratinized Mucosa (MQ) and Gingival Smile Classification will be evaluated. Dental Height and Width will also be assessed; healing parameter, using the Landry Index and postoperative pain measured by the Visual Analogue Scale. Assessments will be carried out at baseline, 4th, 7th, 11th, 14th, 45th days, 3 and 6 months after the surgical procedure. For statistical tests, a significance level or p value < 0.05 and 95% confidence intervals were used.
