FIGURE 2.

Effects of 1‐month use of delmopinol (a), chlorhexidine (CHX); b), and placebo (c) mouthrinses on microbial profiles and diversity of subgingival plaque from dental surfaces and implant surfaces in time. BL, baseline visit; FU1, first follow‐up (1 month); FU2, second follow‐up (3 months). F‐ and p‐values are based on restricted PERMANOVA. Boxplots are based on Tukey. D, dental plaque; I, implant plaque. Connectors indicate a significant difference in diversity between timepoints (Wilcoxon signed ranks test) [Colour figure can be viewed at wileyonlinelibrary.com]
