Ch. 10 Gingival and Dentogingival Junctional Tissue Flashcards

Flashcards for review of Gingival and Dentogingival Junctional Tissue lecture.

What type of tissue surrounds the teeth and is important in periodontal health?

Gingiva

What is the tightly bound, keratinized tissue from the mucogingival junction to the free gingiva called?

Attached gingiva

What is the gingiva between adjacent teeth that forms interdental papillae?

Interdental gingiva

What is the non-visible concave area apical to the contact between facial and lingual papillae?

Gingival col

What is the free gingiva at the edge of the gingival margin?

Marginal gingiva

What is the shallow depression dividing attached and marginal gingiva?

Free gingival groove

What is the peak of gingival tissue around a tooth crown?

Gingival apex of contour

What type of firm oral mucosa includes attached gingiva and the hard palate?

Masticatory mucosa

What is the interface between the tooth and gingiva, including the sulcular and junctional epithelium?

Dentogingival junction

What type of epithelium lines the gingival sulcus and is nonkeratinized?

Sulcular epithelium (SE)

What type of epithelium forms the epithelial attachment to the tooth and has the fastest turnover rate?

Junctional epithelium (JE)

What fluid from the lamina propria enters the sulcus and aids in defense?

Gingival crevicular fluid (GCF)

What is the hemidesmosomal basal lamina attachment between the tooth and JE?

Epithelial attachment (EA)

What is the inflammation limited to the gingiva that is reversible?

Gingivitis

What is the chronic progression of gingivitis that causes irreversible damage to supporting structures?

Periodontitis

What condition is marked by lifesaver-shaped marginal gingiva from edema?

McCall's festoon

What is the fibrous tissue enlargement of the gingiva, often drug-induced?

Gingival hyperplasia

What is the apical migration of the gingival margin called?

Gingival recession

What is the deepened sulcus due to attachment loss, lined by pocket epithelium?

Periodontal pocket

What does CAL stand for, and what does it measure?

Clinical Attachment Level: Distance from CEJ to base of sulcus/pocket.

Name two examples of Periodontopathogens?

A. actinomycetemcomitans and P. gingivalis.

What is the width of attached gingiva in the maxillary incisor region?

3.5 to 4.5 mm

What is the width of attached gingiva in the mandibular incisor region?

3.3 to 3.9 mm

What is the probing depth of a healthy gingival sulcus?

0.5 to 3 mm (average: 1.8 mm)

Which tissue forms the first attachment to the tooth?

Reduced enamel epithelium (REE) forming JE

Which type of graft uses only lamina propria, not epithelium?

Subepithelial connective tissue graft (SECTG)

Which epithelium has the fastest turnover time in the oral cavity?

Junctional epithelium (4-6 days)

What condition is marked by rolled marginal gingiva from edema?

McCall's festoon

What condition is associated with gingival overgrowth due to medications?

Gingival hyperplasia

How long does junctional epithelium take to turnover?

4 to 6 days

What structure does ameloblasts help form after enamel maturation?

Primary epithelial attachment (EA)

What is a major indicator of early gingivitis?

Bleeding on probing

What's the space between the tooth and sulcular epithelium called?

Gingival sulcus

What forms during apical migration of JE in periodontitis?

Periodontal pocket

Is gingivitis reversible?

Yes
