Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Magnitude of the hyperemia after PORH test | Blood flow changes are measured by LSCI before (baseline), during and after gingiva compression. The scale is an arbitrary unit (0-3000 LSPU); relative changes to the baseline measurement will be calculate. | 5min | |
Secondary | Longevity of the hyperemia after PORH test | Blood flow changes are measured by LSCI before (baseline), during and after gingiva compression. The scale is an arbitrary unit (0-3000 LSPU); relative changes to the baseline measurement will be calculate. | 20min | |
Secondary | Size of the hyperemia after PORH test | Blood flow changes are measured by LSCI before (baseline), during and after gingiva compression. LSCI can measure in several cm2 areas and display blood perfusion as color-coded images. | 20 min | |
Secondary | Difference in the magnitude and longevity of hyperemia induced by PORH test next to an implant born crown between women and men. | Blood flow changes are measured by LSCI before (baseline), during and after gingiva compression. The scale is an arbitrary unit (0-3000 LSPU); relative changes to the baseline measurement will be calculate. | 20 min |
