Mean DNA probe count of 41 taxa in supragingival plaque samples from 57 Sjögren’s subjects and 53 healthy subjects. Data for each species were averaged within a subject and then across subjects in the 2 clinical groups separately. The significance of differences among groups was sought using the Kruskal-Wallis test and adjusted for multiple comparisons (Socransky et al. 1991). *P < 0.05. **P < 0.01. ***P < 0.001. Species were ordered according to the complexes described by Socransky et al. (1998).
