NCT05441371

Brief Summary

The purpose of the study is to test the antibacterial effect of Parodontax toothpaste on plaque formation, and thus gingivitis compared to placebo toothpaste. Each subject will be given 2 plastic splints that are individually adapted to their quadrant 1 and 2. In the splint in the 1st quadrant, Parodontax test toothpaste will be placed, while in the splint in the 2nd quadrant, regular toothpaste will be placed, which the subject uses daily. Each person's set of teeth is otherwise professionally cleaned.
