Figure 5. BSE images illustrating laminations in outer enamel.

Figure 5

a. Regularly spaced laminations (arrows) are visible in the outer portion of the enamel (E). In contrast, no laminations are discernible in central and inner enamel. D = dentin. Cuspal to top. b. Detail of Figure 5a. Laminations (arrows) in outer enamel. Note that the outcrop of a lamination on the OES is mostly associated with the presence of a small trough (furrow) on the surface. However, single laminations reach the enamel surface without producing a trough (arrowhead). Cuspal to top.
