Design outcomes

Primary

Measure	Time frame
Comparative assessment of periodontal pocket depth after treatment in the case and control groups. Timepoint: 3 months. Method of measurement: Using a scaled periodontal probe, the distance between the gingival wall and the tooth surface from the gingival margin to the uppermost part of the junctional epithelium is measured and recorded.;Comparative assessment of clinical attachment loss (CAL) after treatment in the case and control groups. Timepoint: 3 months. Method of measurement: Using a scaled periodontal probe, the distance between the border of the enamel and cementum (Cemento-Enamel Junction) to the depth of the pocket is measured and recorded.;Comparative assessment of bleeding on probing (BOP) after treatment in the case and control groups. Timepoint: 3 months. Method of measurement: Checking the presence or absence of blood leakage 30 seconds after probing the periodontal pocket.	—
