Design outcomes

Primary

MeasureTime frame
Evaluate the average probing depth. The probing depth, distance from the gingival margin to the bottom of the sulcus or periodontal pocket, will be evaluated with millimeter periodontal soda in the four sites (mesial, buccal, distal and lingual/palatine) of all present teeth. The probing depth will be recorded in millimeters and the average will be calculated for each individual considering the number of teeth and sites present. Probing depth will be assessed before the intervention and 60 and 90 days after the intervention. A greater reduction in mean probing depth is expected in the test group after intervention compared to the control group. a difference of 1mm in mean probing depth between groups is considered significant.

Secondary

MeasureTime frame
Evaluate bleeding on probing. Bleeding on probing will be evaluated with millimeter periodontal soda in the four sites (mesial, buccal, distal and lingual/palatal) of all present teeth. Bleeding on probing will be recorded as present or absent and the average will be calculated for each individual considering the number of teeth and sites present. Probing bleeding will be assessed before the intervention and 60 and 90 days after the intervention. A greater reduction in mean probing bleeding is expected in the test group after intervention compared to the control group.
