Table 1. Total biofilm weight and microbiological colony count of total microbiota and Candida spp. according to treatments (amoxicillin/clavulanate potassium or placebo) and daily frequency of sucrose exposure (0 – no exposure; exposure – 3 or 8 times/day).

Results are expressed as median (minimum – maximum values) – n = 11.

CFU: colony-forming units.

Distinct lower-case superscript letters indicate statistical significance for the comparison between treatments within each frequency of sucrose exposure (p<0.05; Wilcoxon Signed-Rank test).

Distinct capital superscript letters indicate statistical significance for the comparison among different frequencies of sucrose exposure within each treatment (p<0.05 – Friedman test; p<0.017 – Post-hoc analysis with Wilcoxon Signed-Rank Tests conducted with a Bonferroni correction).
