The dentinoenamel junction or dentin-enamel junction (DEJ) is the boundary between the enamel and the underlying dentin that form the solid architecture of a tooth. [1] It is also known as the amelo - dentinal junction, or ADJ. [2]

2005年2月13日 · 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...

2016年9月10日 · In the crowns of human teeth, beneath enamel, a 200–300 μm zone of resilient (less mineralized and elastic) dentin has been found in the DEJ (Zaslansky et al. 2006). The strain distribution in the 200 μm thick zone in dentin beneath the DEJ is a structural adaptation for transferring and minimizing stress (Wang and Weiner 1997 ).

The dentinoenamel junction (DEJ) is an example of a material system in which structural hierarchy contributes significantly to the performance of teeth (Chai et al., 2009; Goldberg et al., 2002; Imbeni et al., 2005; Marshall et al., 2001, 2003; White et al., 2000).

The dentin-enamel junction (DEJ) plays an important role in preventing crack propagation from enamel into dentin. This function stems from its complex structure and materials properties which are different from either dentin or enamel.

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 fl aws formed in the brittle enamel1.

The structure and mechanical properties of the dentin-enamel junction (DEJ) in human teeth play a critical role in transferring stress from hard enamel to soft dentin efficiently in order to preserve the longevity of this functionally gradient biocomposite.

The dentin-enamel junction (DEJ) is known for its special role in teeth. Several techniques were applied for the investigation of the DEJ in human sound molar teeth. The electron (EPMA) and proton (PIXE) microprobes gave consistent indications about the variability of elemental concentrations on this boundary.

2006年4月14日 · The Dentin–enamel junction (DEJ) is a natural junction that unites two mechanically dissimilar calcified tissues: hard, brittle enamel and the subjacent softer, tougher dentin. The DEJ structure, an effective obstacle for enamel-initiated crack propagation, is generally described as a series of 25–100-μm-diameter scallops with their ...

The dentinoenamel junction (DEJ) is a complex and poorly defined structure that unites the brittle overlying enamel with the dentin that forms the bulk of the tooth. In addition, this structure appears to confer excellent toughness and crack deflecting properties to the tooth, and has drawn consider …
