From: Comparison of in vivo 3D cone-beam computed tomography tooth volume measurement protocols

Three-dimensional visualization of inter-observer volume differences for the whole tooth measurement. (A) Entire tooth volume. (B) Entire tooth volume with maximum inter-observer variability removed from palatal root. (C) Entire tooth volume with maximum inter-observer variability removed from apical portion of all three roots. (D) Entire tooth volume with maximum inter-observer variability removed from buccal surfaces of the mesiobuccal and distobuccal roots.
