The enamel covers the exposed parts of the softer underlyingdentine, and is composed of irregular 4-6-sided columns, the enamelprisms, closely placed and generally vertical to the surface of thedentine. After suitable isolation the enamel prisms appear slightlyvaricose in outline, the minute concavities producing the irregulardark bands often seen traversing the prisms. The prisms are heldtogether by a delicate layer of cement-substance and grouped into Fig 1^3 NORMAL HISTOLOGY. bundles which cross one another, producing the alternate dark andlijrht radial bands seen in the enamel.
