Table 4

Mean values (±SD) of bacterial cells and extracellular polysaccharides biomass, expressed in μm³⋅μm⁻², of topically treated biofilms of Streptococcus mutans UA 159.

Group	S. mutans cells	Exopolysaccharide matrix (EPS)
A. gratissima (Ag4)	15.63 ± 2.56▼	14.90 ± 7.73▼
B. dracunculifolia (Bd2)	33.41 ± 19.16▼	27.99 ± 14.85▲
C. sativum (Cs4)	22.83 ± 12.63▼	20.49 ± 12.08▲
L. sidoides (Ls3)	17.45 ± 4.34▼	16.68 ± 7.01▼
Vehicle	36.32 ± 32.77	20.00 ± 3.41

Note: the arrow “▼” indicates statistically significant reduction of cells or EPS compared to the control, whereas the arrow “▲” indicates statistically significant increase of cells or EPS compared to the control (one-way ANOVA with Dunnett’s multiple comparison test, with a significance level of 5%).
