Design outcomes

Primary

Measure	Time frame
Pocket Probing Depth. Timepoint: before treatment,1 month and 3 month after treatment. Method of measurement: The distance between the gingival margin and the pocket base, which will be measured at 6 points of each tooth (mesiobuccal, buccal, distobuccal, distolingual, lingual and mesiolingual) with the use of a Williams graduated probe. The mean probing depth at each site will be registered as the probing depth in that area.;Clinical Attachment Level. Timepoint: before treatment,1 month and 3 month after treatment. Method of measurement: Williams probe.;Gingival Level. Timepoint: before treatment,1 month and 3 month after treatment. Method of measurement: Williams probe.;Modified Gingival Index. Timepoint: before treatment,1 month and 3 month after treatment. Method of measurement: Observation.;Papillary Bleeding Index. Timepoint: before treatment,1 month and 3 month after treatment. Method of measurement: Periodontal probe and observation.;Porphyromonas gingivalis. Timepoint: before treatment,1 month and 3 month after treatment. Method of measurement: Real time polymerase chain reaction.;Tannerella forsythia. Timepoint: before treatment,1 month and 3 month after treatment. Method of measurement: Real time polymerase chain reaction.;Treponema denticola. Timepoint: before treatment,1 month and 3 month after treatment. Method of measurement: Real time polymerase chain reaction.	—
