| 释义 |
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. The dentinoenamel junction is thought to be of a scalloped structure which has occurred as an exaptation of the epithelial folding that is undergone during ontogeny. This scalloped exaptation has then provided stress relief during mastication and a reduction in dentin-enamel sliding and has thus, not been selected against, making it an accidental adaptation.[3] References1. ^A.Nanci.
