Fig. 3From: Adjunct use of mouth rinses with a sonic toothbrush accelerates the detachment of a Streptococcus mutans biofilm: an in vitro studySEM images of the biofilm structure remaining on the disc after each experimental treatment (C, C + ST, G + ST, and L + ST). The upper row depicts representative SEM images of the dense area of the biofilm structure in each experimental group. The lower row shows representative SEM images of the sparse area of the biofilm structure in each experimental group. Scale bar, 20 μmBack to article page
