Comparison of Oral Microbe Quantities from Tongue Samples and Subgingival Pockets

Table 4

Spearman’s correlation coefficients (; 95% confidence intervals) between clinical periodontal variables at the mesiobuccal site and relative abundances from subgingival pockets (site level).

(95% CI)	Subgingival plaque

P. gingivalis	0.26 (0.12, 0.39)	0.18 (0.05, 0.30)
A. actinomycetemcomitans	0.18 (0.03, 0.31)	0.10 (−0.03, 0.22)
F. nucleatum	0.23 (0.09, 0.36)	0.07 (−0.06, 0.20)
S. sanguinis	0.07 (−0.08, 0.21)	−0.07 (−0.19, 0.06)
Archaea	0.18 (0.04, 0.31)	0.05 (−0.08, 0.18)
% Archaea	0.17 (0.02, 0.30)	0.04 (−0.09, 0.17)
Total bacteria	0.15 (0.01, 0.29)	0.12 (−0.01, 0.24)
