- Statistic method: Pearson chi-square test
- Mutans streptococci counts: Low = <105 CFU; Medium = 105- < 106 CFU; High = ≥106 CFU
- Lactobacilli counts: Low = ≤104 CFU; Medium = 105 CFU; High = ≥106 CFU
- Buffer capacity (final pH): Low = blue; Medium = green; High = yellow
- Oral hygiene: Low = QH 0.0-2.0; Medium = QH 2.1-3.4; High = QH 3.5-5.0
- Intake frequency: Low = ≤4 per day; Medium = 5-6 per day, High = ≥7 per day
- Fluoride exposure: Low = no fluoride used; Medium = fluoride toothpaste is used; High = fluoride supplements are used in combination with fluoride toothpaste
- Saliva secretion rate (only for 10-year old children): Low = <0.25 ml/min; Medium = 0.25-0.49 ml/min; High = > 0.5 ml/min
- NS no statistically significant difference
