Relative abundance of S. mutans in saliva · Individuals assessed for dental caries, predominantly children with early childhood caries (ECC) or severe ECC (age about 1 to 4 years)
A few small studies report Streptococcus mutans relative abundance in caries versus caries-free children without pooling; the evidence is ungraded and not meta-analyzed.

Relative abundance of Veillonella spp. · Individuals assessed for dental caries, predominantly children with early childhood caries (ECC) or severe ECC (age about 1 to 4 years)
Evidence on whether Veillonella spp. relative abundance is higher or lower in children with dental caries than caries-free controls is inconsistent across 7 small observational studies; no pooled estimate was produced and the evidence is ungraded.
