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

Measurement protocol Volume measured ICC CI (lower bound) CI (upper bound) F-text,pvalues
Protocol 1: manual Whole tooth 0.885 0.707 0.967 F (9,18) = 24.158, p < .0005
Protocol 1: manual Roots apical to CEJ 0.904 0.749 0.973 F (9,18) = 29.406, p < .0005
Protocol 2: automated Whole tooth 0.826 0.697 0.952 F (9,18) = 12.215, p < .0005
Protocol 2: automated Roots apical to CEJ 0.899 0.742 0.953 F (9,18) = 27.512, p < .0005
Protocol 3: automated with refinements Whole tooth 0.996 0.989 0.999 F (9,18) = 767.557, p < .0005
Protocol 3: automated with refinements Roots apical to CEJ 0.904 0.751 0.973 F (9,18) = 29.406, p < .0005
  1. CEJ = cemento-enamel junction; CI = confidence interval; ICC = intra-class correlation coefficient.
