Periodontitis patient with stage II (moderate periodontitis) to stage IV (advanced periodontitis with extensive tooth loss) based on clinical attachment loss (CAL) of ≥ 3 mm around the teeth and disease severity according to 2017 international periodontology workshop were selected. As all patients in our study didn’t have full mouth periapical radiography and no risk factor that may affect systemic health according to eligible patients, the grade of periodontitis was estimated with moderate progression rate (grade B).For all the patients, the probing depth (PD) was measured by the Williams probe, which is a distinctive and calibrated device, at six points of each tooth: mesiobuccal, mid-buccal, distobuccal, mesiolingual, mid-lingual, and distolingual. These areas were coded, and 10 points were randomly selected from at least three quadrants for the post-intervention clinical measurements [Clinical attachment loss (CAL) was also recorded in these areas by measuring the distance between the CEJ (cementoenamel junction) and the pocket depth. In addition, the O’Leary plaque index [
