Figure 3.

Effect of rinse, mechanical control of biofilm, and disease on saliva buffering capacity. 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 log10 transformation. 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 = 0.007 (β-1 = 0.79) ηp² = 0.13 and No mechanical control of biofilm: α = 0.23 (β-1 = 0.22) ηp² = 0.03). Simple effects for Rinse in children with ECC—Mechanical control of biofilm: α = 0.01 (β-1 = 0.72) ηp² = 0.11 and No mechanical control of biofilm: α = 0.07 (β-1 = 0.43) ηp² = 0.06. Simple effects for Biofilm in CF children—Pre-rinse: α = 0.19 (β-1 = 0.26) ηp² = 0.03 and Post-rinse: α = 0.04 (β-1 = 0.55) ηp² = 0.08. Simple effects for Biofilm in children with ECC—Pre-rinse: α = 0.09 (β-1 = 0.39) ηp² = 0.05 and Post-rinse: α = 0.04 (β-1 = 0.49) ηp² = 0.07. Simple Effects for Disease in Pre-rinse condition—Mechanical control of biofilm: α = 0.04 (β-1 = 0.56) ηp² = 0.08 and No mechanical control of biofilm: α = 0.12 (β-1 = 0.33) ηp² = 0.04. Simple Effects for Disease in Post-rinse condition—Mechanical control of biofilm: α = 0.06 (β-1 = 0.46) ηp² = 0.06 and No mechanical control of biofilm: α = 0.04 (β-1 = 0.56) ηp² = 0.08.
