SEM morphological observations of the Streptococcus mutans biofilms. The effect of ID23029 on biofilm formation and architecture. The untreated control biofilms were confirmed by the images at ×800 magnification (a) and 2,500× (b). The biofilms of the test group were incubated for 72 h after treatment with 25 mg/mL of ID23029, and their formation was confirmed by the images at a magnification of 800× (c) and 2,500× (d)
