Flashcards in the periodontium Deck (24):
what is free gingiva?
coronal epithelial attachment
what is attached gingivae?
tightly bound to underlying bone
what are some signs of gingival health?
firm, pale, pink, stippling, no BOP, knife edged ID papilla,
what are the 4 layers of oral epithelium?
3-granular cell layer
what are the 3 regions of gingival epithelium?
1-oral gingival epithelium
2-oral sulcular epithelium
name some features relating to oral gingival epithelium
-stratified squamous epithelium
name some features relating to the oral sulcular epithelium
-lines the gingival sulcus/crevis
-rete peg pattern
-not directly involved with epithelial attachment
name some features associated with junctional epithelium
-forms epithelial attachment to the tooth
-cells shed from the JE into the gingival crevice
name 4 cells found in gingival connective tissues
what are the 5 different collagen fibres?
what is collagen?
-collagen is a complex network of polysaccharides and proteins secreted by cells
what is the function of the pdl?
what are the 5 principle fibres?
what are the fibers called that attach cementum(root) to the bone?
wha are the 3 main vessels of pdl?
what are the 2 directions of oxytalan fibers?
-parallel to root surface
-oblique to the root surface
what are the two different types of cementum?
what is 'page &shroeder'
-the different lesions (4 phases)
what are the 4 phases of page and shroeder?
1- initial lesion
4- advanced lesion
what is the initial lesion?
-early stages of gingivitis
-24-48 hrs of plaque accumulation
-vasodilation, increase PMNs &GCF
what is the early lesion?
-Ig production and cytokine release
-loss of fibroblasts and collagen
-increased GCF and gingival swelling
what is the established lesion?
-gingival connective tissue largely replaced by inflammatory exudate
-JE shows rete peg growth and ulceration
-bacterial products cause damage
what is the advanced lesion?
-fibrosis in connective tissue
-ulceration and migration of JE
-breakdown of PDL fibres
