Figure 2.

Effect of rinse, mechanical control of biofilm, and disease on saliva pH. Statistical analyses were performed in a sample of 56 volunteers, 28 per group. ηp²: Partial eta squared. Data plotted as mean and standard deviations (due to Gaussian distribution). Non-significant interactions were suppressed. A single asterisk represents a significant p-value ≤ 0.05. A double asterisk represents p-value ≤ 0.01. Simple effects for Rinse in CF children—Mechanical control of biofilm: α = 0.000 (β-1 = 1.00) ηp² = 0.45 and No mechanical control of biofilm: α = 0.005 (β-1 = 0.82) ηp² = 0.14). Simple effects for Rinse in children with ECC—Mechanical control of biofilm: α = 0.000 (β-1 = 0.97) ηp² = 0.23 and No mechanical control of biofilm: α = 0.000 (β-1 = 0.97) ηp² = 0.23. Simple effects for Biofilm in CF children—Pre-rinse: α = 0.12 (β-1 = 0.35) ηp² = 0.05 and Post-rinse: α = 0.01 (β-1 = 0.75) ηp² = 0.12. Simple effects for Biofilm in children with ECC—Pre-rinse: α = 0.54 (β-1 = 0.09) ηp² = 0.007 and Post-rinse: α = 0.78 (β-1 = 0.06) ηp² = 0.001. Simple Effects for Disease: No significant effect considering a p-value > 0.05. Supplementary material provides complementary information regarding data statistics.
