Lecture 1 Flashcards
peridontium 3 different states
health
gingivitis
periodontitis
gingiva 4 anatomical areas
free gingiva
gingival sulcus
interdental papilla
attached gingiva
gingival crevicular fluid
increases in the presence of plaque biofilm resulting in gingival inflammation
contained in gingival sulcus
4 types of tissues
epithelial
connective
muscle
nerve
extracellular matrix consists of:
ground substance: gel-like
fibers: collagen, elastin, reticular fibers
extracellular matrix provides
a framework giving connective tissue its strength to withstand mechanical forces
the gingiva consists of both:
epithelial tissue
connective tissue
skin and oral mucosa are made up of
stratified squamous epithelium
gingival epithelium consists of
oral epithelium
sulcular epithelium
junctional epithelium
basal lamina
thin layer of extracellular matrix
gingival connective tissue
more extracellular matrix with less cells
blood vessels and nerve supply
mostly collagen fibers
gingival connective tissue fibers
circular
dentogingival
dentoperiosteal
alveologingival
transeptal
PDL functions
support
sensory
nutrients
formative
resorbtive
sharpey fibers
