Figure 2 in The detection of weakly developed plicidentine in teleost teeth using 3D tomography

Figure 2. - Tomographic imaging of the teeth of various teleostean taxa known to have plicidentine (see the text). A: Arapaima gigas (Arapaimatidae). Lingual dentary plate; the axially sectioned tooth (arrow) corresponds to figure 7 in Meunier et al. (2013); the tooth tip is covered by an enameloid cap (arrowheads); Inset: Virtual cross section of the base of several teeth at various levels, a number of which shows dentin folds in the pulp cavity (asterisks). B-D: Hoplias aimara (Hoplerythrinidae); right premaxilla; B: External view of a fang and a mid-sized caniniform tooth showing the basal ridges (asterisk) and the apical enameloid cap (arrow heads); C: Virtual axial section of the fang showing the folds in the pulp cavity (asterisk), the apical enameloid cap and the premaxillary bone; D: Virtual cross section of the fang (upper) and the mid-sized tooth (lower) showing regular primary folds (arrowheads) and external ridges (arrows); E-F: Lophius piscatorius (Lophiidae); tomographic image of anterior portion of the left palato-pterygoid; E: Basal ridges on the left external surface of a tooth (arrow head); on the right, pulp cavity of two teeth with obvious folds (white arrow). The black arrows point to the attachment bone (bo); F: Virtual cross section of the two teeth on the left on Fig. E; the folds are restricted to a part of the teeth. Scale bars: A, D = 1 mm; B, C, F = 2.5 mm; E = 5 mm.
