Figure 5. The species associated with dental caries.
The abundances of species-level OTUs were statistically analyzed in 3 levels of dental caries in deep and shallow sites, respectively. The species with a significant difference (α = 0.05) in 3 levels of dental caries were shown. HD_shallow, high decay and shallow site; MD_shallow, moderate decay and shallow site; ND_shallow, non-decay and shallow site; HD_deep, high decay and deep site; MD_ deep, moderate decay and deep site; ND_ deep, non-decay in deep site.
