Figure 5 in The detection of weakly developed plicidentine in teleost teeth using 3D tomography

Figure 5. - Dissostichus eleginoides (Nototheneidae); tomographic imaging of the anterior portion of the left premaxilla. A: Virtual model of the whole premaxilla (pmx) showing the external aspect of three caniniform teeth with external basal ridges (arrowheads); a fourth broken tooth shows ridges in the pulp cavity (white arrow); B: Virtual model of the premaxilla (bo) with axial section of the two widest caniniform teeth that show dentine folds in the pulp cavity (black arrowhead); folds are also shown in the broken tooth (white arrowhead); C: Virtual cross section in the tooth base at the level of the vascular aperture showing folds in the pulp cavity (white arrows); D: Virtual cross section, lightly above the previous level in C, showing dentine folds (white arrows) and external ridges (white arrowheads); the dentine core (de) of the tooth is perforated; E: Virtual axial section of the biggest tooth showing thin cavity and canals in the dentine (de); the tooth is covered by a thin enameloid layer; white arrowheads point to folds in the pulp cavity (pc). Scale bars: A, B = 5 mm; C, D = 2 mm; E = 1 mm.
