Biofilm Formation on Root Dentin

Biofilm staining - click for larger versionThe left image shows bacteria (E. faecalis) in a planktonic state on root dentin; we used a fluorescent probe staining for viable (green) and non-viable bacteria (red), which was then visualised in a confocal laser scanning microscope. The right image shows biofilm developed after 3 hours on the same dentin sample in an area where the bacteria could adhere and multiply.
