Clinical and Microbiological Evaluation of Laser Therapy in the Treatment of Periodontal Disease in Stages III and IV
The aim of this clinical trial is to evaluate photodynamic therapy and photobiomodulation in the periodontitis treatment. To evaluate the clinical and microbiological response of conventional periodontal treatment associated with photodynamic therapy and photobiomodulation with red or infrared laser. Participants will receive periodontal treatment carried out with the use 0.005% methylene blue and laser therapy (photodynamic therapy), associated with conventional periodontal treatment, as well as the use of photobiomodulation with red or infrared laser associated with conventional periodontal treatment in participants with periodontitis. So, twenty periodontitis patients will be selected and separated in two groups compared with placebo. Clinical and microbiological parameters will be evaluated at baseline and 3 months after periodontal treatment: plaque Index, bleeding on probe, probing depth, gingival recession and clinical attachment level.
• Adult participants with periodontal disease;
• Four or more periodontal sites with PPD≥6 mm and CAL≥5 mm, non-adjacent;
• Generalized periodontitis, with more than 30% of the sites involved (Caton et al., 2018);
• Stages III and IV of periodontal disease (Caton et al., 2018);
