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

After conventional periodontal treatment, saline gel will be applied in the periodontal pocket and, after 5 minutes, the laser application will be simulated with the device in inactive mode, in order to maintain blinding of the patients.

After conventional periodontal treatment, photosensitization will be performed with 2% chlorhexidine gel with 0.005% methylene blue (Fórmula e Ação Farmácia, São Paulo, SP, Brasil) for 5 minutes and photodynamic therapy will be applied with a rede laser (660nm) usinf DuoⓇ laser (MMOptics, São Carlos, SP, Brazil) with the optical fiber inside the periodontal pocket in back and forth movements, according to the manufacturer's protocol, for 90s, 9 joules of energy, dose of 508.5J/cm2, irradiance of 5.65W/cm2 and power of 100mW.
