Figure 2
(a) 3D rendering of a dentin specimen and its frame of reference. The specimen is in the initial position of rotation, where the beam direction is opposite to the x axis. The rotation axis is parallel to the z axis. A rendered volume of the specimen has dimensions of 832 µm (x) × 832 µm (y) × 702 µm (z). (b) Sketch of a typical human tooth. 1: enamel; 2: pulp; 3: dentin. The tubules run from the dentin–enamel junction to the pulp. The trace of the sagittal plane is shown by a dashed line. (c) Diagram of a dentin specimen used for tomographic experiments after compression tests. Specimen dimensions are typically in the range ∼4–5 mm long (l), ∼2–3 mm wide (w) and ∼0.2–0.5 mm high (h). |
