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. The marginal gingiva is stabilized by the gingival fibers that have no bony support. The gingival margin, or free gingival crest, at the most superficial part of ...
In theory, gingival fibers are the protectors against periodontitis, as once they are breached, they cannot be regenerated.When destroyed, the gingival sulcus (labelled G in the diagram) increases in depth apically, allowing more debris and bacteria to remain in intimate contact with the delicate sulcular and junctional epithelia for longer times.
The gingival margin (F) is the most coronal point of the gingiva, depicted as the zenith of the pink hill in this diagram. To the left lies the sulcular epithelium within the gingival sulcus (G) , and to the right lies the oral epithelium (E) .
Perforating vessels originate from lamina dura and the vessels perforate the socket wall (cribriform plate). Gingival vessels are derived from the gingival tissue. Outer layers of blood supply in PDL may help in mechanical suspension and support of the tooth while inner layers of blood vessels supply surrounding PDL tissues. [11]
The gingival tissue forms a crevice surrounding the tooth, similar to a miniature, fluid-filled moat, wherein food debris, endogenous and exogenous cells, and chemicals float. The depth of this crevice, known as a sulcus , is in a constant state of flux due to microbial invasion and subsequent immune response.
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.
"We use a small probe to measure the space that exists between the tooth and the gum tissue that surrounds it. If this space is between 1 mm and 3 mm, the pocket is classified as healthy. If the ...
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 .
