详细描述
The present study is a double-blinded randomized clinical trial with a duration of 28 days.
80 orally and systemically healthy participant will be allocated in the test (probiotic) and the control (placebo) group at baseline.
The intervention is sugar stress, which will be applied at baseline and continue through day 14, followed by 14 days without sugar stress.
Clinical measurements and sampling will be performed at baseline, day 14 and day 28
Primary endpoint: Changes in microbial composition.
