Gingival complex

Question 1

Epithelium of sulcular epithelium

Answer 1

Non keratinised stratified squamous epithelium

Question 2

Epithelium of free gingiva

Answer 2

Keratinised stratified squamous epithelium

Question 3

Epithelium of attached gingiva

Answer 3

Keratinised stratified squamous epithelium

Question 4

Epithelium of Lining mucosa

Answer 4

Non- keratinised stratified squamous epithelium

Question 5

Epithelium of junctional epithelium

Answer 5

Non- keratinised stratified epithelium

Question 6

Junctional epithelium features

Answer 6

Up to 30 cells wide at its widest
2 basal laminae (against the tooth and adjacent to the connective tissue)
Permeable - inflammatory cells can pass through it

Question 7

What causes stippling

Answer 7

The presence of coarse collagen bundles attaching the epithelium of the attached gingiva to the underlying alveolar bone

Question 8

Transudate GCF

Answer 8

Filtrate of blood arising from increased pressure in veins and blood vessels, forces fluid through the vessel against the plasma osmotic pressure.

This is what you would expect to have in clinically health gingiva

Question 9

Exudate GCF

Answer 9

Fluid which escapes from the intra- vascular to the extra- vascular compartment containing proteins and cellular material, usually as a result of inflammation.

This is what you would expect to have in gingivitis

Question 10

Composition of GCF

Answer 10

Serum, cells, antibodies, inflammatory mediators

Question 11

Is junctional epithelium permeable

Answer 11

Yes - inflammatory cells can pass through
