From: Efficiency of biofilm removal by combination of water jet and cold plasma: an in-vitro study
Scanning electron micrographs showing examples of specimen after 5 days of osteoblastic cell cultivation for water jet (WJ), curette + cotton swab (CC) and their combinations with plasma (WJ + CAP, CC + CAP), negative control (NC) with untreated plaque-biofilm, and untreated positive control PC. The white single arrow points to destroyed osteoblastic cells, the double arrow points to microbes, and the circle marks a scratched area (see also Additional file 3). Scale bars: 10 µm
