Clustering of microbiomes. a. UPGMA (unweighted pair group method with arithmetic mean) tree reveals two microbial clusters. The column leftmost from the tree indicates the positions of the sampled teeth in orange and purple background columns. Next the Periodontal pocket depth (PPD) and Bleeding on probing (BOP) relative values are indicated. The colors in the horizontal bars mark the corresponding elements of the Socransky pyramid. The lengths of the columns are proportional to the relative abundance of the given Socransky group. b. Heat map distribution of the most abundant 30 species in the microbial clusters. c. Significantly different species between the two microbiological clusters. Please nore that these significantly different microbes are not the same as in Fig. 3
