Four species tested showed a correlation between higher levels on teeth and caries, including S. mutans, A. naeslundii/viscosus, V. parvula/dispar, and C. granulosa. One species, D. acidovorans, showed a trend toward association with health (P = 0.08). *, P < 0.05 using Mann-Whitney multivariate logistic regression analysis to account for differences between patients. n = 6 to 10, except general Lactobacillus species, where n = 3 to 7.
