The both groups are then matched for PI, based on the silness-loe plaque index and when treatment of the first area was determined, the next area was treated using another protocol, Blinding description: The patient and the operator are not aware of the laser or placebo, and the third person makes the laser adjustments. 3 Periodontal disease. Intervention group: all oral areas are treated with SRP using ultrasonic pens. Laser is then performed on the experimental group to remove the inner layer of the pockets and thus reduce the microbial load using the diode laser according to the manufacturer's instructions.. Yes - There is a plan to make this available What will be shared: The charts are in periodontics department of Qazvin dental school When: Starting 2 months after pulication To whom: People working in academic institutions Conditions: Access to view and review data Where to obtain: By sending email to drz.alizadeh@gmail.com How to obtain: This process may last about 1 month Comments:

K05.3 Chronic periodontitis Treatment - Devices Intervention group: all oral areas are treated with SRP using ultrasonic pens. Laser is then performed on the experimental group to remove the inner layer of the pockets and thus reduce the microbial load using the diode laser according to the manufacturer's instructions. Periodontal pocket depth(PPD), bleeding index(BI) ,clinical attachment level(CAL). Timepoint: Before intervention and 1 and 3 months after intervention. Method of measurement: PPD is measured in millimeters from the free gingival margin to the base of the periodontal pockets using a manual periodontal probe. BI was defined as the presence or absence of bleeding 30 seconds after probing (±). CAL is also defined as the distance (mm) from cementoenamel junction (CEJ) to the bottom of the pockets.
