E.5 End points |
E.5.1 | Primary end point(s) |
Efficacy Primary criterion The main criterion will be the evolution of the Loe and Silness Gingival Index (GI) during the study: mean change between D0 and D14 calculated on 6 sites (3 vestibular and 3 palatin) around 6 target teeth, excluding wisdom teeth. Safety - local tolerance: aspect of the mouth mucosa, - general tolerance (adverse events), Statistical analysis - efficacy:non-parametric analysis of covariance, -safety: descriptive analysis. |
