Evaluation of Antimicrobial Photodynamic Therapy in Multiple Applications as a Coadjuvant in the Surgical Therapy of Access to Scaling

After the sites are indicated for surgical therapy, they receive surgical access therapy associated with scaling and root planing and TfdA using the treatment protocol during periods of 0, 7, 14 and 30 postoperative days, or only surgical access therapy associated with scaling and root planing. As protocol, TfdA will be used laser light source 660nm wavelength in combination with phenothiazine, a photosensitizer with 10 seconds of exposure per site during surgery and 60 seconds in other applications.

Scaling and root planing, also known as conventional periodontal therapy, or deep cleaning, is a procedure involving removal of dental plaque and calculus (scaling or debridement) and then smoothing, or planing, of the (exposed) surfaces of the roots, removing cementum or dentine that is impregnated with calculus, toxins, or microorganisms, the etiologic agents that cause inflammation. This helps to establish a periodontium that is in remission of periodontal disease. Periodontal scalers and periodontal curettes are some of the tools involved.
