Figure 3.
Principal coordinate analysis (PCoA) among caries-active (CA, blue), periodontitis (P, red), caries-active and periodontitis (CAP, yellow) and healthy controls (H, brown). The PCoA plot showed a reasonable separation of samples from caries-active (blue), periodontitis (red) and healthy controls (brown). The samples from CAP (yellow) were located at the overlap of caries-active and periodontitis groups and were clearly separated from the healthy controls (brown).
