crystals structures. The hydroxyapatite crystals are hexagonal in shape, providing rigidity to the prism and strengthening the enamel. In cross-section, it is best compared to a complex “keyhole” or a “fish-like” shape. The head, which is called the prism core, is oriented toward the
118:. The prism core has tightly packed hydroxyapatite crystals. On the other hand, the prism sheath has its crystals less tightly packed and has more space for organic components. These prism structures can usually be visualised within ground sections and/or with the use of a 141:
Enamel prism are found in rows along the tooth. Within each row, the enamel prism's long axis is generally perpendicular to the underlying ADJ amelo-dentinal junction, which is also called the dentino-enamel junction. Such is the case in both permanent and
