Primary

Measure	Time frame
Inflammation of the gums. Timepoint: Measuring the level of inflammation based on the target index at the beginning of the study (before the intervention) and one month after the intervention. Method of measurement: Based on direct observation.;Dental plaque. Dental plaque is a collection of microorganisms present on the surface of the tooth as a biofilm, which is placed in a matrix of polymers of host and bacterial origin. Timepoint: Measuring the amount of dental plaque based on the target index at the beginning of the study (before the start of the intervention) and one month after the start of the intervention. Method of measurement: Based on direct observation.;Stain; Pigment deposits on the tooth surface are called dental stain. Timepoint: Measuring the amount of dental stain based on the target index at the beginning of the study (before the start of the intervention) and one month after the start of the intervention.
