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.
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]
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.
Plasma cell gingivitis appears as mild gingival enlargement and may extend from the free marginal gingiva on to the attached gingiva. [6] Sometimes it is blended with a marginal, plaque induced gingivitis, or it does not involve the free marginal gingiva. It may also be found as a solitude red area within the attached gingiva (pictures).
The excessively detailed stippled surface texture of the base area (false gums) can be observed, mimicking the physiologic stippling of gum tissue in nature. Note how there is minimal to no stippling on the marginal gingiva, which is the millimeter or so of pink immediately adjacent to the teeth .
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 ...
Thus, the JE does not mature like keratinized tissue, such as the marginal gingiva or attached gingiva, which fills its matured superficial cells with keratin. Nor does JE mature on a lesser level like nonkeratinized tissue of the sulcular gingiva and throughout the rest of the oral cavity, which enlarges its cells as they mature and migrate ...
