Temporal change in the total amount of bacteria, microbial richness and diversity.

(A) Temporal change in the total amount of bacteria on a hydroxyapatite disk. (B) Temporal change in the number of operational taxonomic units (OTUs), Shannon diversity index and phylogenetic diversity in the plaque microbiota on a hydroxyapatite disk. To correct for the unequal number of sequences, we evaluated 800 randomly selected sequences. The error bars indicate the standard error.
