Evaluation of Chlorhexidine Gel Associated with Photodynamic Therapy in the Treatment of Chronic Periodontitis in Type 2 Diabetics

Plain-language summary

The objective of this clinical trial is to evaluate chlorhexidine gel associated with photodynamic therapy in the treatment of chronic periodontitis in Type 2 diabetics The main questions it aims to answer are: • To evaluate if the use of 2% chlorhexidine gel associated with 0.005% methylene blue and laser therapy is superior to conventional periodontal treatment associated with photodynamic therapy in Type 2 diabetics Participants will receive periodontal treatment carried out with the use of 2% chlorhexidine gel associated with 0.005% methylene blue and laser therapy, associated with conventional periodontal treatment, as well as the use of photodynamic therapy associated to conventional periodontal treatment in Type 2 diabetics patientes. So, 20 periodontitis patients will be selected. Patients will be separated in two groups; Test, use of 2% chlorhexidine gel associated with 0.005% methylene blue and laser therapy + Periodontal Disease with PD\> 5mm and Control, conventional periodontal treatment with gel control with fisiological solution + Laser therapy. Clinical parameters and microbiological parameters were evaluated at baseline and 3 months after periodontal treatment: Plaque Index, Bleeding On Probe, Probing depth, Gingival Recession and Clinical Attachment Level, and Microbiological parameters will be checked by PCR, for evaluating A.a, P.g., T.f., C.albicans.
