Multiple apical foramina forming a branching pattern at the apex of a tooth reminiscent of a river delta when sectioned and viewed through a microscope that occurs in some brachyodont teeth

Ameloblasts

Epithelial cells involved in the formation of enamel (amelogenesis)

Enamel (E)

Mineralized tissue covering the crown of brachyodont teeth

Anatomical crown (CR/AC)

That part of a tooth that is coronal to the cementoenamel junction (or anatomical root)

Clinical crown (CR/CC)

That part of a tooth that is coronal to the gingival margin; also called erupted crown in equines

Anatomical root (RO/AR)

That part of a tooth that is apical to the cementoenamel junction (or anatomical crown)

Clinical root (RO/CR)

That part of a brachyodont tooth that is apical to the gingival margin

Cementoenamel junction

Area of a tooth where cementum and enamel meet

Reserve crown (CR/RC)

That part of the crown of a hypsodont tooth that is apical to the gingival margin
