1
thickness of junctional epithelium coronally
15- 30 cells
2
tissues of the periodontium?
gingiva, cementum, periodontal ligament, alveolar bone
3
role of GCF
defense against microbes and inflammation
4
NAME THE THREE EPITHELIUM
junctional, sulcular, oral
5
what is the internal lamina basal?
Thin layer of extracellular matrix between epithelial cells and enamel
6
What is the significance of keratinised tissue
Not under pressure, not waterproof , very permeable
7
function of rete pegs?
Large surface area provides strength and support from pressure
8
Functions of gingival connective tissue
Strength /integrity, transportation, host response
9
functions of junctional epithelium
attachment, barrier, host defence
10
what are rete pegs (found in oral epithelium) ?
Ridges that join with the connective tissue in a wavy pattern
11
What is the contact point between two teeth gingival?
col
12
layers of the oral epithelium
basal, prickle, granular, keratinised
13
What are desmosomes
connect epithelial cells
14
What is the external basal lamina
Thin layer of extracellular matrix between epithelial cells and gingival connective tissue
15
Characteristics and function of sulcular epithelium
thin, non keratinised, no rete pegs, semi permeable allowing GCF, no epithelial ridges
16
Gingival connective tissue...?
Attaches the gingiva to the cementum of the root and the alveolar bone
17
What are hemidesmosones
Attaches to connective tissue, attachment to tooth surface by them and internal basal lamina
18
only the oral epithelium is keratinised
true
19
Supragingval fibres of connective tissue
Hold teeth in place , made of collagen, gingivitis destroys fibres
20
thickness of junctional epithelium apically
4-5 cells
21
describe the layers of the junctional epithelium
stratified squamous cells, thin, delicate, couple of layers thick
