Fig. 1From: Genetic polymorphism of scrA gene of Streptococcus mutans isolates is not associated with biofilm formation in severe early childhood cariesBiofilm formation of Streptococcus mutans isolates from caries free group and severe early childhood caries group. Streptococcus mutans isolates were incubated on 96-well flat-bottom plates in 1% sucrose BHI media for 24 h. The biomass of Streptococcus mutans isolates from caries free (CF) group and severe early childhood caries (S-ECC) group were evaluated by crystal violet assay. The results showed that isolates from S-ECC group have a higher biomass than CF groupBack to article page
