Effect of Photodynamic Therapy as an Adjunct to Non-Surgical Treatment of Periodontitis

Sponsor: Egas Moniz - Cooperativa de Ensino Superior, CRL

Summary

Photodynamic therapy (PDT) is an innovative technique that utilizes light-activated agents, known as photosensitizers, to produce reactive oxygen species capable of targeting and eliminating pathogens. This therapeutic approach has been explored in a variety of medical fields due to its versatility and minimal invasiveness. In the context of periodontal diseases, PDT has emerged as a promising adjunctive treatment in the non-surgical management of periodontitis. Periodontitis, a chronic inflammatory disease caused by the accumulation of pathogenic bacteria in the subgingival environment, is often treated with mechanical debridement, including scaling and root planing (SRP). However, these conventional methods may not always achieve complete bacterial eradication. PDT, when used in conjunction with SRP, has the potential to significantly enhance bacterial elimination. The use of photosensitizers, activated by specific wavelengths of light, leads to the generation of singlet oxygen, which can effectively kill a broad spectrum of periodontal pathogens, including those resistant to antibiotics. As an adjunctive therapy, PDT can improve the clinical outcomes of non-surgical periodontitis treatment by reducing bacterial load, promoting tissue healing, and potentially decreasing the need for more invasive procedures. The ability of PDT to target bacteria without harming surrounding tissues makes it an attractive option for patients who require a non-invasive treatment approach. In conclusion, photodynamic therapy is a valuable addition to periodontal treatment regimens, offering enhanced bacterial reduction and improved therapeutic outcomes in the management of periodontitis.
