In order to find out more about the bacteria species that cause early childhood caries, investigators looked at the microbial composition of dental plaque in 42 children with early childhood caries and 40 children without dental caries. Results showed the presence of a pathogen that was not previously known to cause caries: Scardovia wiggsiae. Scardovia wiggsiae was associated with severe early childhood caries and were found in the mouths of children with early childhood caries even when Streptococcus mutans was not. Streptococcus mutans, Veillonella parvula, Streptococcus cristatus and Actinomyces gerensceriae were the other species found to be associated with early childhood caries. Streptococcus mutans and Scardovia wiggsiae were the main caries related species.
