Figure 2

Scanning electron microscopy of Streptococcus mutans biofilms treated with the selected active fractions from selected essential oils and the vehicle. Images a, b, c, and d show the reduction of biofilm formation after treatment with Ag₄, Bd₂, Cs₄, and Ls₃ fractions, respectively, compared with the treatment with the vehicle (image (e)) (magnification of 7000x).
