Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the changes in microbial composition of the oral microbiome after two weeks of regular oral hygiene and use of inulin-containing mouth rinse (wash-in phase), followed by two weeks abstaining from any oral hygiene combined with the use of inulin-mouth rinse (experimental gingivitis phase), and the recovery period of two weeks with normal oral hygiene combined with inulin-mouth rinse use (recovery phase) compared to the baseline and a mouth-rinse containing a placebo rinse. | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the changes 1) in gingival light absorption (GLA), 2) in proportion of the red fluorescing plaque (RFP) and 3) in gingival bleeding on marginal probing (BOMP) after two weeks of regular oral hygiene and use of inulin-containing mouth rinse (wash-in phase), followed by two weeks abstaining from any oral hygiene combined with the use of inulin-mouth rinse (experimental gingivitis phase), and the recovery period of two weeks with normal oral hygiene combined with inulin-mouth rinse use (recovery phase) compared to the baseline and a mouth-rinse containing a placebo rinse. | — |
