Enamel is as brittle as glass and yet it can constantly withstand bite forces during chewing as high as 1,000 N many times a day. [11] [12] As such, it has been argued, that enamel tufts is an example of how nature has created a biomechanical solution to the problem of weak internal interfaces that laminate structures would otherwise have. [8]
The dentinoenamel junction or dentin-enamel junction (DEJ) [1] is the boundary between the enamel and the underlying dentin that form the solid architecture of a tooth. It is also known as the amelo - dentinal junction, [ 2 ] or ADJ.

Enamel spindles are often confused with two other entities: enamel lamellae and enamel tufts. Lamellae are linear enamel defects that extend from the surface of the enamel towards the DEJ, or vice versa. Enamel tufts are "small, branching defects that are found only at the DEJ, protruding into the enamel towards the enamel surface.
Enamel mineralization only occurs once (as ameloblasts are lost with eruption within the reduced enamel epithelium); therefore after amelogenesis, enamel production has been finalized. [4] This is in contrast to dentin formation which occurs throughout life (secondary dentin production).
