Gingiva Flashcards
When is it referred to as a ‘pocket’
greater than 3 mm
appearance of ‘stippling’
due to the rete/peg/ridge of the epithelium going into the connective tissue - interdigitations
arterial supply to gingiva
respective branches of maxillary and mandibular arteries
capillary loops
in the papillary layer which is immediately subajacent to the basal epithelial cells and they are important in the gingivial physiology - increased in blood during inflammation - why you see increase in redness
krause’s bulbs
in the lamina propria and function in responding to cold sensitivity - known as an organized nerve ending
disease of gingival epithelium will lead to?
loss of barrier of integrity and possible ulcer formation
- like mucositis (inflammation/ ulcer formation) following head and neck cancer radiation therapy
disease of gingival corium will lead to?
rapid loss of tooth-supporting /tooth investing tissue
vimentin
intermediate filament of PDL fibroblast
- also with many cells of mesenchymal origin
Keratin
intermediate filament protein of the epithelium - and epithelial cells and their derivatives
migration rate of gingival epithelium in a day/ how does this occur
about .5mm/day actin /thin filaments myosin/thick filaments myosin proteins microtubules intermediate filaments = keratins
this is fast which reinfoorces tha tthis is a well developed cytoskeleton for cell movement and migration
intermediate filament of muscle
desmin
junctions common in gingiva
adherens cell-cell and cell-to matrix
adhesion belts
desmesomes
adhesion belts
via cadherins and actin
desmesomes
via cadherins and keratin
adhesion protein for hemidesmosome
integrin - alpha and beta adhesion protein
