Effect of an Enzyme-containing Lozenge on Dental Biofilm in Healthy Individuals.

Preventive Effect of an Enzyme-containing Lozenge on Dental Biofilm Accumulation in Healthy Individuals: A Clinical Pilot Study.

The purpose of the study is to assess the effect of an enzyme containing lozenge on dental plaque accumulation in healthy adults.

The purpose of this study is to examine the clinical effects of a lozenge containing enzymes on dental plaque accumulation and oral microbiome composition after professional dental cleaning, as compared to a placebo lozenge without enzymes. Furthermore, safety of the enzyme lozenge will be assessed by clinical evaluation of the oral hard and soft tissues. The null hypothesis is that the treatment with enzyme-containing lozenges do not affect plaque accumulation, as compared to a placebo control.
