The marginal gum varies in width from 0.5 to 2.0 mm from the free gingival crest to the attached gingiva. The marginal gingiva follows the scalloped pattern established by the contour of the cementoenamel junction (CEJ) of the teeth. The marginal gingiva has a more translucent appearance than the attached gingiva, yet has a similar clinical ...
Gingival retraction or gingival recession is when there is lateral movement of the gingival margin away from the tooth surface. [1] [2] It is usually termed gingival retraction as an intentional procedure, and in such cases it is performed by mechanical, chemical, or electrical means in order to perform certain dental surgery procedures.
The gingival fibers, (H), extend from the cementum (B) into the attached gingiva. Some fibers extend coronally into the crest of the free gingiva, some horizontally, and still other extend horizontally over the crest of the alveolar bone, (C), and then apically to connect on the facial aspect of the buccal plate of the alveolar bone.
The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the mesial and distal surfaces of the teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the ...
A gingival pocket presents when the marginal gingiva experiences an edematous reaction, whether due to localized irritation and subsequent inflammation, systemic issues, or drug induced gingival hyperplasia. Regardless of the etiology, when gingival hyperplasia occurs, greater than normal (the measurement in a pre-pathological state ...
Masticatory mucosa, keratinized stratified squamous epithelium, found on the dorsum of the tongue, hard palate, and attached gingiva. Specialized mucosa, specifically in the regions of the taste buds on lingual papillae on the dorsal surface of the tongue; contains nerve endings for general sensory reception and taste perception.

The width of attached tissue is critical, because the more there is available provides a greater sense of protection against the aforementioned insults to the tissue. Using the mucogingival junction as the boundary demarcating the apical border of the attached gingiva, a periodontal probe is inserted into the gingival sulcus to measure how much ...
The tooth is attached to the surrounding gingival tissue and alveolar bone (C) by fibrous attachments. The gingival fibers (H) run from the cementum (B) into the gingiva immediately apical to the junctional epithelial attachment and the periodontal ligament fibers (I), (J) and (K) run from the cementum into the adjacent cortex of the alveolar bone.
