This will be a randomized, double-blind, split-mouth clinical trial lasting 12 months. Participants will be selected from the Department of Periodontology of the Faculty of Dentistry of Bauru (FOB-USP). The sample will consist of systemically healthy individuals aged between 18 and 70 years. Patients will be included in the study if they meet the following inclusion criteria: (1) clinical diagnosis of multiple gingival recessions with at least one gingival recession ≥ 2 mm, including canines and premolars; (2) Miller class I and II gingival recession areas; (3) non-abrasive, erosive or carious root surfaces (4) unrotated, non-extruded and non-movable teeth (5) systemically healthy patients without contraindication to periodontal surgical procedures. The exclusion criteria will be: smokers, pregnant women, patients with a history of periodontal disease or recurrent abscess formation, patients previously submitted to surgical procedures for root coverage, patients taking anti-convulsant drugs, antihypertensives, contraceptives or immunosuppressors, patientes with low oral hygiene (plaque and bleeding index over 20%). The experimental protocol will be sent to the FOB-USP Human Research Ethics Committee for evaluation. Participants will receive detailed information about the study and will sign the Informed Consent Form after understanding all the steps of the research. All selected patients will be submitted to basic periodontal procedures (scaling, root planning, coronary polishing and oral hygiene instructions) before performing the surgical procedures. Patients should present plaque index and bleeding ≤ 20% throughout the study period.
