What happens to the epithelial attachment if periodontal disease is present?
What happens to the epithelial attachment if periodontal disease is present?
What is the classic definition of the presence of periodontal disease? It is attachment loss with the presence of plaque-induced gingival inflammation and radiographic evidence of bone loss.
Where is epithelial attachment located?
A collar of non-keratinized epithelial cells forming the biological attachment to the tooth surface at the base of the gingival crevice (sulcus) in the region of the cemento-enamel junction (CEJ). It is formed from the reduced enamel epithelium.
How does junctional epithelium attached to tooth?
The gingival sulcus is bound by the enamel on the crown of the tooth and the sulcular epithelium. The junctional epithelium is immediately apical to the base of the pocket, and coronal to the most coronal of the gingival fibers. The JE is attached to the surface of the tooth with the EA.
What are the attachment tissues of the teeth?
The two mineralized tissues, cementum and alveolar bone, are the abutments to which the fibrous periodontal ligament anchors the tooth into the skeleton. The gingiva is the covering tissue of the periodontium and offers immediate protection for the underlying tissues as well as additional attachment of the tooth.
Does clinical attachment loss mean bone loss?
These observations indicate that attachment loss precedes radiographic evidence of crestal alveolar bone loss during periods of periodontal disease activity.
What is epithelial cuff?
A band of nonkeratinized stratified squamous epithelium that attaches both to the gingiva (on one side) and the crown of the tooth (on the other). Synonym: epithelial attachment; gingival cuff.
Is junctional epithelium attached gingiva?
The junctional epithelium (JE) adjacent to the tooth is that part of the gingiva which attaches the connective tissue to the tooth surface (Fig. 2.14).
Does junctional epithelium regenerate?
The regenerating nerve fibers completely bypassed the zone of epithelial down-growth (long junctional epithelium, LJE) that was briefly present along the tooth from 1-3 weeks after injury. The LJE did not have p75-NGFR-IR and was gradually replaced by a modified thicker regenerated junctional epithelium (RJE).
Why is attached gingiva important?
Historically, the presence of a wide zone of attached gingiva has been considered beneficial, as the gingiva plays an important role in maintaining the periodontium in health. It provides a physical barrier to oral biofilm, dissipates masticatory forces and protects the periodontium from injury.
What is the tissue that surrounds the roots of the teeth and connects them to the alveolar bone?
Periodontal Ligament. A system of collagenous connective tissue fibers that connect the root of a tooth to its socket.
What is attachment loss in dentistry?
Clinical attachment loss occurs when the collagen fibers of the periodontal ligament detach from the cementum on the root surfaces of teeth, causing the gingiva to migrate toward the roots of the teeth, exposing the roots and eventually causing the affected tooth to loosen, migrate, or fall out.
