Enamel tufts

This is a histologic cross-section of a tooth and shows enamel (top right, slightly reddish with crack to the surface edge in corner) and dentin (bottom left, two slightly purplish light and then dark bands). The lightish boundary between them is the dentinoenamel junction. From this can be seen enamel tufts growing towards the top right.

Enamel tufts are hypomineralized ribbon-like structures that run longitudinally to the tooth axis and extend from the dentinoenamel junction (DEJ) one fifth to a third into the enamel. They are called ‘‘tufts’’ due to their wavy look within the enamel microstructure.
