Effects of Periodontal Treatment Associated With Antimicrobial Photodynamic Therapy on Halitosis in Patients With Diabetes Mellitus

Effects of Periodontal Treatment Associated With Antimicrobial Photodynamic Therapy on Halitosis in Patients With Diabetes Mellitus: A Randomized Clinical Trial

The goal of this clinical trial is to evaluate the effectiveness of periodontal treatment associated with the use of a tongue scraper, compared with the same treatment combined with antimicrobial photodynamic therapy (aPDT), in reducing halitosis in individuals with periodontal disease and type 2 diabetes mellitus. The main question it aims to answer is: aPDT treatment is more effective in treating halitosis? aPDT treatment is more effective in periodontitis? Researchers will compare aPDT treatment to conventional treatment (scaling and root planning and tongue scraper) to see if aPDT has additional effects in reducing halitosis and improving periodontal health.
