      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Single, Purpose: Treatment, Randomization description: For random specialization of quadrants and their selection as an intervention or control unit, dual block randomization method will be used. (For patients who have 4 complete quadrants to participate in the study and for patients who have only 2 quadrants are eligible to participate in the study Random number assignment method will be used), Blinding description: Due to the fact that each patient selected in the study will be both an intervention group and a control group, they will enter the study split-mouth, ie the patient's mouth will be divided into equal quadrants and a quadrant as a control group under SRP treatment. It will be equipped with ultrasonic devices and hand-held scaling devices, and a quadrant as a laser group will be treated with a diode laser in addition to the SRP, and ultimately the outcome assessor will be completely unaware of the grouping.</study_design>
