Clinical Trial Summary

With this design, this study hypothesizes that; (i) ICG-PDT would produce superior clinical, microbiological, and immune-inflammatory outcomes as compared to RSD and (ii) ICG-PDT would produce equal efficacy among different forms of diabetes as produced in non-diabetic subjects and that diabetes mellitus would not produce negative impact on the therapeutic outcomes of ICG-PDT. Therefore, the aim of this randomized controlled clinical trial was to evaluate the efficacy of ICG-mediated aPDT in the treatment of stage III grade C periodontitis among patients with prediabetes, T2DM and non-diabetic subjects.

Intervention

Drug:
• Indocyanine green
Single application of PDT will be performed. A diode laser (HELBO®TheraLite - Bredent Medical, Germany) with 670 nm wavelength, power of 150 mW, fluency of 22 J/cm2 and density of 1.1 W/cm2 will be used in this study. Indocyanine-green photosensitizer (Sigm Aldrich, USA) with 0.005% concentration will be used as a photosensitizer which will be applied inside the periodontal pockets in a depth of 3 mm with the help of a blunt needle for 10 s. Laser irradiation will be performed for 60 s using a flexible tip. Laser irradiation will be performed at 2 points each on buccal and lingual with the tip stabilized perpendicular to the gingival tissues.
