junction (jungk´shn),

n a place of coming together, or union.

junction, cementoenamel (CEJ) (cervical line),

n the junction of the enamel of the crown and the cementum of the root of a tooth. The area above the junction corresponds to the anatomic crown of the tooth; the area apical to the junction constitutes the anatomic root of the tooth.

junction, dentinocemental (DCJ),

n the line of union or apposition of the cementum and dentin of a tooth.

junction, dentinoenamel (DEJ) (dentoenamel junction),

n the interface of enamel and dentin of the tooth crown, conforming in a general way to the shape of the crown. Older term is
dentoenamel junction.

junction, dentoenamel,

n See junction, dentinoenamel.

junction, dentogingival (DGJ),

n the junction between the gingival attachment, a nonkeratinized epithelium, and the tooth surface.

junction, intercellular,

n a special structure that exists between two or more cells with similar functionality. Most of these structures are anchored to the cytoskeleton and therefore provide mechanical stability to tissues. There are several types, including desmosomes that provide stability, tight junctions where the outer membranes of cells have become fused, and gap junctions where adjacent cells exchange cellular material.

junction, mucogingival,

n the scalloped linear area denoting the separation of the gingivae and alveolar mucosa.
