Figure 5.

Effect of rinse, mechanical control of biofilm, and disease on salivary α-amylase. Statistical analyses were performed with a sample of 56 volunteers, 28 per group. ηp²: Partial eta squared. Data plotted as median and interquartile range (due to non-Gaussian distribution). To fulfill the ANOVA premises, we used the square root for data. Non-significant interactions were suppressed. A single asterisk represents a significant p-value ≤ 0.05. Simple effects for Rinse in CF children—Mechanical control of biofilm: α = 0.45 (β-1 = 0.12) ηp² = 0.01 and No mechanical control of biofilm: α = 0.74 (β-1 = 0.06) ηp² = 0.002. Simple effects for Rinse in children with ECC—Mechanical control of biofilm: α = 0.28 (β-1 = 0.19) ηp² = 0.02 and No mechanical control of biofilm: α = 0.03 (β-1 = 0.59) ηp² = 0.09. Simple effects for Biofilm in CF children—Pre-rinse: α = 0.04 (β-1 = 0.56) ηp² = 0.08 and Post-rinse: α = 0.09 (β-1 = 0.40) ηp² = 0.05. Simple effects for Biofilm in children with ECC—Pre-rinse: α = 0.42 (β-1 = 0.13) ηp² = 0.01 and Post-rinse: α = 0.04 (β-1 = 0.56) ηp² = 0.08. Simple Effects for Disease: No significant effect considering a p-value > 0.05. Supplementary material provides complementary information regarding data statistics.
