|---|---|
| Probing pocket depth. Timepoint: Baseline, one month, three month. Method of measurement: Probing pocket depth was measured to nearest millimeter from gingival margin to base of the clinical pocket by William`s periodontal probe.;Clinical attachment loss. Timepoint: Baseline, one month, three month. Method of measurement: it was calculated as distance in millimeter from a cement-enamel junction to the bottom of probable pocket at experimental sites.;Bleeding upon probing. Timepoint: Baseline, one month, three month. Method of measurement: recording the presence or the absence of bleeding up to 30 second after probing with a William`s periodontal probe. Bop was measure in 6 sites per each tooth. | — |
