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.
Desquamative gingivitis involves lesions of the free and attached gingiva.Unlike plaque-induced inflammation of the gums (normal marginal gingivitis), desquamative gingivitis extends beyond the marginal gingiva, involving the full width of the gingiva and sometimes the alveolar mucosa. [3]
Normal gingiva may range in color from light coral pink to heavily pigmented. The soft tissues and connective fibres that cover and protect the underlying cementum, periodontal ligament and alveolar bone are known as the gingivae. The gingivae are categorized into three anatomical groups: the free, attached and the interdental gingiva.
The alveolar bone (C) is surrounded for the most part by the subepithelial connective tissue of the gingiva, which in turn is covered by the various characteristic gingival epithelia. The cementum overlaying the tooth root is attached to the adjacent cortical surface of the alveolar bone by the alveolar crest (I) , horizontal (J) and oblique (K ...
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 marginal gingiva has a more translucent appearance than the attached gingiva, yet has a similar clinical appearance, including pinkness, dullness, and firmness. In contrast, the marginal gingiva lacks the presence of stippling, and the tissue is mobile or free from the underlying tooth surface, as can be demonstrated with a periodontal probe.
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.
At the free gingival margin, the sulcular epithelium is continuous with the gingival epithelium. Both the attached gingivae and the free gingivae are included as part of the gingival epithelium. While the junctional epithelium is a stratified and thin epithelium that is attached to the tooth surface, the epithelium of the gingival sulcus is ...
