Lecture 6- Dental plaque induced gingivitis Flashcards
6 common characteristics to all gingival diseases
signs and symptoms limited to gingiva
presence of dental plaque
signs of imflammation
symptoms assoc. on a periodontium with no CAL or on a stable but reduced periodontium
reversibility of the disease by removing the etiology
possible role as a precursor to CAL
common clinical changes from health to gingivitis involve 5 different aspects
color texture/edema bleeding exudate plaque
inflamed gingiva turns red because there is …. vascularization and … epithelial keratinization
increased
decreased
severely inflamed gingiva turns red and cyanotic because of … proliferation and reduction in … + …

venous stasis
gingival bleeding occurs because there is … and … of the capillaries and … or … of the sulcular epithelium
dilation and engorgement
thinning or ulceration
With inflammation, the consistency of the gingiva changes so there is an increase in … and degeneration of… and engorged … and thinning of epithelium

in severe gingival disease, the gingiva has … with grayish flake-like debris (necrosis)
sloughing
chronic inflammation can produce this unexpected change in the consistency of the gums
firm, leathery
fibrosis and epithelial proliferation
T/F stippling is lost with inflammation

one of the main modifiers or gingival diseases are …
endocrine factors (pregnancy, puberty and menstrual cycle assoc gingivitis)
what nutritional deficiencies modify gingival diseases
def. of vitamin C (scurvy)
lack of vitamin A, B2 and B12
3 commonly used drug types that are associated with gingival overgrowth
(BOARD Q)
anticonvulsants (phenytoin sodium or epinutin)
immunosuppressant (cyclosporin A)
Calcium channel blocking agents (nifedipine)
what population usually presents with necrotizing ulcerative gingivitis (NUG)
adolescents or young adults, may be smokers and usually assoc with psychological stress
the clinical symptoms of NUG are …
pain
ulceration and necrosis of interdental papillae
