Composition of microbiota in saliva and dental plaque samples. (A) The Venn plot shows the overlap and differences between the microbiota of dental plaque and salivaa. The blue area represents saliva samples, and the yellow area represents dental plaque samples. (B) Microbial network composition of dental plaque and saliva, with different colored points denoting different species and each species' contribution indicated by the size of the point. (C) Relative abundance of species composition at the genus level in the two groups, with lines connecting samples from saliva (blue) and dental plaque (yellow). (D) Wilcoxon test, indicating significance levels for Actinomyces, Corynebacterium, and Prevotella (* P < 0.05, ** P < 0.01). E Relative abundance of species composition at the phylum level
