Closer view of (a) the coronal area of the Straumann® Tissue Level Standard implant; (b) confocal laser scanning microscopy (CLSM) of the 96 h biofilms on the implant surfaces. Specimens were stained with the LIVE/DEAD® BacLightTM Bacterial Viability Kit solution (Molecular Probes B. V., Leiden, The Netherlands) containing SYTO9 and propidium iodine nucleic acid stains. Cells that were dead or dying bacteria were stained in red (PI) whereas cells with an intact membrane were stained in green (SYTO9).
