What is the Amelodentinal Junction? The point at which the enamel and dentine meet. Microscopically it has a scalloped appearance. From: amelodentinal junction in A Dictionary of Dentistry »
Where is the Amelodentinal Junction? The line around the tooth that marks the boundary between the crown and root of the tooth; the interface between enamel and cementum.
What is the DEJ of a tooth? The dentin-enamel junction (DEJ), which is the interfacial region between the dentin and outer enamel coating in teeth, is known for its unique biomechanical properties that provide a crack-arrest barrier for flaws formed in the brittle enamel1.
Why is dentino enamel junction scalloped? As a consequence, dentine and enamel would be pushed towards each other during loading (i.e., during mastication). These findings suggest that the scalloped nature of the DEJ confers a biomechanical advantage to the integrity of the tooth during mastication.

What is the shape of DEJ?
The DEJ is a complex structure associating two calcified tissues, preventing the propagation of cracks from enamel to dentin. It is a scalloped structure with convexities toward dentin and concavities toward enamel (Shimizu & Macho 2007 , Brauer et al.
