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.
Gingival recession is when there is an apical movement of the gum margin away from the biting (occlusal) surface. [4] It may indicate an underlying inflammation such as periodontitis [ 5 ] or pyorrhea , [ 5 ] a pocket formation, dry mouth [ 5 ] or displacement of the marginal gums away from the tooth by mechanical (such as brushing), [ 5 ...
In dental anatomy, the gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for groove ) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin .
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 ...
The clinical importance of the mucogingival junction is in measuring the width of attached gingiva. [1] Attached gingiva is important because it is bound very tightly to the underlying alveolar bone and provides protection to the mucosa during functional use of the structures of the oral cavity during function, such as chewing.
Healthy gingiva can be described as stippled, pale or coral pink in Caucasian people, with various degrees of pigmentation in other races. The gingival margin is located at the cemento-enamel junction without the presence of pathology. The gingival pocket between the tooth and the gingival should be no deeper than 1–3mm to be considered ...
A number of different 'margins' are involved in dentistry. The edge of tooth structure that is prepared to meet the edge of a prosthetic crown is called a margin, as is the aforementioned edge of the crown; an example of this usage would be "a poorly fitting crown might exhibit marginal leakage."
The terms alveolar border, alveolar crest, and alveolar margin describe the extreme rim of the bone nearest to the crowns of the teeth. [ 7 ] [ 8 ] [ 9 ] The portion of alveolar bone between two adjacent teeth is known as the interdental septum (or interdental bone).
