Figure 5 Figure 5 Human cementum surface, made anorganic, showing mineralized ends of extrinsic fibers, 6 μm diameter, separated by intrinsic fibers.

Figure 6 Figure 6 Human alveolar bone surface made anorganic. The resorption lacunae reveal that the extrinsic (Sharpey's) fibers were only partly mineralized. The remainder of the surface was forming, as evidenced by incomplete mineralization of intrinsic and extrinsic fibers.
