Design outcomes

Primary

MeasureTime frame
Gingival inflammation and bleeding measured by Gingival Index (Löe & Sillness 1963) at baseline, week 2, 4, and 8

Secondary

MeasureTime frame
Measured at baseline, week 2, 4, and 8: 1. Gingivitis-associated oral fluid biomarkers: whole Saliva and GCF (both collected at the clinic) were quantitatively analyzed for the amount of matrix-metalloproteinase (MMP)-8 and interleukin (IL)-1ß by means of ELISA technique 2. Dental plaque measured by Plaque Index (Silness-Löe 1964)
