Design outcomes

Primary

Measure	Time frame
Treatment status. Timepoint: Baseline study, one month after the beginning of the intervention and two months after the beginning of the intervention. Method of measurement: Treatment index: First, the number of decayed, missing and filled teeth in primary (dmft) and permanent (DMFT) dentition, will be assessed.Treatment index will be calculated by these formulas:((M+F)/DMF)100 and ((m+f)/dmf)100 .Also, D, M, F, d, m, f indices will be reported separately.;Gingival bleeding. Timepoint: Baseline study, one month after the beginning of the intervention and two months after the beginning of the intervention. Method of measurement: Bleeding on probing index (BOP): The presence or absence of gingival bleeding in all teeth will be evaluated using the WHO Periodontal Probe. The surrounding gingiva of each tooth is assessed for the presence or absence of bleeding.;Oral hygiene. Timepoint: Baseline study, one month after the beginning of the intervention and two months after the beginning of the intervention. Method of measurement: Oral Hygiene Index-simplified (OHI-S): The Calculus Index (CI) and Debri Index (DI) for six teeth (16,11,26,36,31,46) will be evaluated and will be scored from 0 to 3 for each tooth and will be recorded in the examination form. The sum of calculus scores, divided by the number of examined teeth will represent the CI and and the sum of debri scores, divided by the number of examined teeth will represent the DI. Finally, the sum of CI and DI will be reported as OHI-S.	—
