Sketch of the flow chamber and flow chamber system.
A) Assembly drawing with test specimen; B) General setup of the closed circuit system. The red arrows indicate the direction of the flow.

3D reconstruction of biofilms in side view.
The cells were stained live/dead and analysed by CLSM. Vital cells are depicted in yellow, viable cells in blue. A) S. gordonii, B) S. oralis, C) S. salivarius, D) P. gingivalis, and E) A. actinomycetemcomitans.
Fig 3.
Biofilm heights on titanium substrata in the flow chamber system.
In each diagram, the mean biofilm heights for five independent experiments are shown. A = S. gordonii, B = S. oralis, C = S. salivarius, D = P. gingivalis, and E = A. actinomycetemcomitans.
