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.
This is one of the axial sections viewed from a sagittal perspective. If you look carefully, you can see the biofilm appears to be constructed “in layers” and every so often you can observe these “layers” peeling off so you can see what is “underneath”. All of what you are looking at is a biofilm. […]
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 […]
Scheduled for a GW…then I took a CBCT…….. No way, Jose……. Tried to minimize the access just for practice…… not even close to Nishan territory but still trying….. gbc
Tim, What I learned from my bench studies is that, yes, the GW will uncover canal orifii that you didn't realize were there
