Semithin longitudinal section of tooth (t) and jaw (j) in the region where the tooth protrudes from the jaw (at the bottom of the photograph). The pillar bridges on the surface of the tooth have vanished. The ligament can be seen at the top of the micrograph (arrow), but gradually degrades towards the bottom, where a number of cells and extracellular material of indistinct structure fill the space between tooth and jaw.

Figure 27. Semithin longitudinal section through the vanishing tooth ligament. The space between tooth (t) and jaw (j) is crowded with cells that replace the ligament. Figure 28. Ultrathin section of a presumed phagocyte in the degrading tooth ligament. Arrow points to an invagination that contains collagen-like fibrils.
