Effect of calcium on bacterial adhesion. Calcium-supplemented irrigation (shaded bars) decreased adhesion of S. aureus (A), P. aeruginosa (B), and E. coli (C) to fibroblast GD-25 cells and type I collagen compared with irrigation with HEPES-buffered water without calcium (open bars). All data are normalized to bacterial adhesion. (n=18, *p<0.0005)
