(a) Genus-level summary of bacterial communities present in plaque and saliva. Each pair of bars represents one patient, with pre-intervention sample on the left and post-intervention sample on the right of the pair. Plaque and saliva samples are vertically aligned by corresponding patient; (b) boxplots expressing relative sequence abundance of ZOTU1_S. salivarius, mutans streptococci and all other streptococci, relative to the total relative sequence abundance of all Streptococcus sequences. The solid line within each box indicates the median value for each group; data were compared using ANOVA with Tukey’s post-hoc test.
