Adjunctive Photodynamic Therapy in Treatment of Chronic Periodontitis
Efficacy of Adjunctive Photodynamic Therapy in Non-surgical Treatment of Chronic Periodontitis: a Randomized , Controlled Clinical Trial
Sponsor: Fundação de Amparo à Pesquisa do Estado de São Paulo
Listed as NCT01034501, this PHASE4 trial focuses on Chronic Periodontitis and remains completed. Sponsored by Fundação de Amparo à Pesquisa do Estado de São Paulo, it has been updated 6 times since 2010, reflecting limited change activity. This study adds to the evidence base for this therapeutic area through structured, versioned documentation.
Study Description(click to expand)The goal of periodontal treatment is to restore tissue health through the elimination and control of etiologic factors, reducing the microbial aggression. Some microorganisms persist in the root surface even after scraping. Thus, the conventional mechanical treatment may fail to reduce the number of periodontal pathogens to levels compatible with health. This study will verify the efficacy of Photodynamic Therapy (PDT) as an adjunct to non-surgical treatment of chronic periodontitis.
