Mean number and mean rank of bands according to treatments (amoxicillin/clavulanate potassium or placebo) and daily frequency of sucrose exposure (0 – no exposure; exposure – 3 or 8 times/day).

SD: standard deviation; n = 11.With regard to the mean number and the mean rank of bands, no statistical significance was found either for different treatments (p>0.05; Paired T-test) or for different frequencies of sucrose exposure (p>0.05; Repeated Measures ANOVA test).Note: Although 54 distinct bands have been detected in the DGGE profile analyses, none of the volunteers presented all of them in their profile.
