I'm sure I could help with this, but it depends a lot on how much of the tooth/filling has been segmented.  Also, as I'm not a dentist I'm not sure what part of the filling would be considered the isthmus; looking top-down on the tooth, could you find the first slice containing canal but no isthmus in the current segmentation and clear it (using the paint brush tool on the filling mask and pressing "E") and then run a connected component filter on the isthmus to extract it?  Having a model to examine would make solving this a lot easier.

Best wishes,

Paul Holcomb

"Dear author's Seg3d 2.1 tutorial PDF,

I am Ph.D. student and I am trying to measure the volume of the root canal filling material in the isthmus of mandibular molars mesial canals (the material in the space between the canals). How can I measure just the volume in the isthmus excluding the filling material inside the main canals lumen?
In the data filters I selected the neighborhood connected and put seed points in the filling material. I can measure the total volume of the canal filling, including the two canals of the mandibular mesial root and isthmus area, but I don´t know how to measure only the isthmus.
I could select the paint tool or polyline tool this area, but it is difficult and not very trustful… There is an easier way to do that?
If you could help me, I would be very glad.
Thank you"

If you could help me with it I would be very glad.
