Conditions

Dental plaque and one of the following endpoints: - enamel decalcification/white spot lesions - remineralized caries at the fissures and accessory cusps - caries - tartar - fluorosis Oral Health

Interventions

At the screening, a dental plaque assessment is performed by a dental professional followed by the exams of enamel decalcification/white spot lesions, remineralization of caries at the fissures and ac

Design outcomes

Primary

MeasureTime frame
At a single time point: 1. Dental plaque (pre-brushing) measured by test device and examiner based dental plaque index. 2. Enamel decalcification/ white spots measured by Enamel Decalcification Index. 3. Oral Conditions (by tooth/surface presence of remineralization of caries at the fissures and accessory cusps, caries, tartar, fluorosis) measured by appropriate common indices.

Secondary

MeasureTime frame
There are no secondary outcome measures.
