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

What this Trial Is About

Researchers are evaluating the effectiveness of periodontal treatment combined with a tongue scraper, compared with the same treatment plus antimicrobial photodynamic therapy (aPDT), in reducing bad breath (halitosis) in people who have periodontal disease and type 2 diabetes. The trial aims to determine if adding aPDT to conventional treatment is more effective for treating halitosis and improving periodontal health. This study is a randomized clinical trial sponsored by the University of Sao Paulo. Participants will receive one of two treatments: scaling and root planing with antimicrobial photodynamic therapy applied to periodontal pockets and the tongue, or scaling and root planing with a tongue scraper only. Treatments will be given once a week for one month. After this active treatment phase, participants will attend maintenance and control visits once a month for up to six months. During the study, participants will visit the clinic weekly during treatment and monthly during follow-up. Researchers will assess halitosis from enrollment through six months, along with periodontal health measurements such as probing depth and clinical attachment level. These evaluations will help determine the added effects of aPDT compared to conventional treatment. The total participation time covers one month of active treatment plus six months of follow-up.
