Enamel Spindles at the DEJ
In this ground section, dentin (A) lies to the lower right, enamel (B) to the upper left. The black lines seen in the dentin represent odontoblast processes (C). Note that a few of these processes project across the D-E junction (D) into the enamel. These finger-like projections of odontoblast processes, not withdrawn during cytogenesis at the DEJ, are referred to as enamel spindles (E). Being extensions of the odontoblast process, they do not conform with the direction of enamel rods.
