This should illustrate better

If we look at the cut section along the edge of the calal so we observe the biofilm edge-on—you can see how these layers are constructed.

It is helpful to recall Dr. Costerton’s diagramatic pics of mature biofilms to develop a conceptual understanding of what you are observing. In looking at “the good root” in our fracture case (the root that wasn’t fractured), one wouldn’t expect a mature biofilm…but that is exactly what we see….everywhere. Shedding of planktonic cells from the […]

Had many emails on how to interpret some of the sections from our “fracture case” on TDO. I forget I’ve been looking at biofilms for almost 15 years so fail to remember how confusing they can be…..I’ll publish a series that may help. In most cases, biofilms look different from planktonic organisms. Biofilms enmesh themselves […]
