The aim of this study was to evaluate the effect of two different treatment agents used in conjunction with subepithelial connective graft technique on root coverage outcomes in multiple recession defects. Half of patients will receive root treatment with antimicrobial photodynamic therapy and the other half will receive photobiomodulation therapy by laser on surgery site.
Antimicrobial photodynamic therapy has been widely used in Periodontics to obtain reduction of periodontopathogenic bacteria with absence of systemic side effects and minimal bacterial resistance. Also, it has properties of root demineralization and exposure of collagen fibers. These properties may enhance root coverage in procedures of subepithelial connective graft. Laser photobiomodulation has the potential to increase healing and repair, this can generate gains in the root coverage and dental hypersensitivity.

In the procedure of subepithelial connective tissue graft, exposed dental roots will be treated by scaling and root planing only.
In the procedure of subepithelial connective tissue graft, exposed dental roots will be treated by antimicrobial photodynamic therapy with toluidine blue O (10mg/ml)
After the procedure of subepithelial connective tissue graft the whole surgical site will receive red laser application.

Total root coverage
Total root coverage measured with a periodontal probe in millimeters. Ideal if the distance from cemento-enamel junction to gingival margin = 0 mm
Time frame: One year
Keratinized mucosa width
Keratinized mucosa width is measured with a periodontal probe in mm, from gingival margin to mucogingival junction. Ideal if keratinized mucosa width \> 5mm
Time frame: One year
Probing depth
Probing depth measured with a periodontal probe in millimeters. The distance from gingival margin and the apical point of gingival pocket or sulcus. Ideal if \<2mm.
Time frame: One year
Clinical attachment level
Clinical attachment level measured with a periodontal probe in millimeters. The distance from cemento-enamel junction and the apical point of gingival pocket or sulcus. Ideal if \<2mm.
Time frame: One year
Dentin hypersensitivity
Dentin hypersensitivity measured by applying an air jet on teeth and patient fills up a visual analogue scale. Ideal if = 0.
Time frame: One year
