Table 3 Comparison of richness and diversity estimates of 16S rRNA gene libraries at 97% similarity between Group BP and BFP.

From: Comparing dental plaque microbiome diversity of extrinsic black stain in the primary dentition using Illumina MiSeq sequencing technique

  1. Values are presented as the Mean ± SD. BP Plaque samples from EBS-positive subjects. BFP Plaque samples from EBS-free subjects
  2. a,bRichness estimators (Chao 1 and ACE) were calculated using MOTHUR
  3. cA higher number indicates less diversity
  4. *One-way ANOVA test was used
