FIG 3-2

Dentinoenamel junction

The dentinoenamel junction (DEJ) in a developing tooth. Enamel matrix (EM) is present. Dentinal tubules (DT) are spaced more widely at the DEJ than further into the dentin (D) (H and Lee stain; ×640).

FIG 3-3

Dentinal tubules

Branching dentinal tubules (arrow) in developing dentin (D) near the dentinoenamel junction (DEJ). Other branches are faintly visible in the deeper dentin (H and Lee stain; ×640).

FIG 3-5

Dentinal tubules

Cross section of dentinal tubules near predentin (PD) shows the globular nature of calcification in circumpulpal dentin. Variably shaped calcification centers, referred to as globular dentin (GD), leave relatively uncalcified areas around the asterisks (H and Lee stain; ×400).

FIG 3-6

Dentinoenamel junction

Dentinoenamel junction (arrows) in a mature tooth. Enamel is represented by the enamel space (ES). Dentinal tubules are visible in the dentin (D) (H and Lee stain; ×640).

Dentinal tubules

Cross section of dentinal tubules (arrows) in a mature, decalcified tooth (H and E stain; ×640).
