Segmentation criteria for using SegmentGeometry to calculate 2nd moments

I am planning to use Segment Geometry from SlicerBiomech Extension to calculate 2nd moments of area for mouse mandibles based on cross sections. Mouse have large incisors, should I remove them and other teeth or include them for calculating 2nd moments of area?

I saw that in the tutorial video for a cat mandible, the teeth were kept there. Perhaps teeth do not matter?

My second question is, how accurate the cross-section segmentation should be? I can’t find an efficient way to segment out the small cavities (see picture below), particularly those in the trabecular bone. If these small holes are filled, would it impact much of the second moments of area calculation?

Any suggestions would be appreciated! Thanks in advance! @jmhuie
