Bacteria Flashcards
Actinomyces viscosus
root surface caries, healthy gingiva
* primary cause
Prevotella intermedia
acute necrotizing gingivitis and pregnancy gingivitis
- Gram-negative obligate anaerobic bacteria generally found in
Streptococcus salivarius
associated with the tongue
- Gram-positive cocci
Streptococcus mutans
Enamel caries
- Acidogenic/aciduric = metabolizes sucrose to lactic acid, which can demineralize enamel
- glucosyltransferase converts sucrose to glucans and fructans
Streptococcus sanguinis
first bacterial species to adhere to tooth structure
Lactobacillus
Dentinal caries
Most common organism in chronic perio?
Anaerobic G-
In general, predominant Supra gingival to the associated attached plaque?
G+ rods and cocci
Primary bacterial colonizers of the tooth in plaque?
G+ anaerobic
Fusobacterium nucleatum
Large bridging bacteria
Red complex
P Gingivalis
T denticola
T forsythia
Orange Complex
Fusobacteria
Prevotella intermedia
Campylobacter recurs
A actinomycetemcomitans
Aggressive periodontitis
** leukotoxin kills neutrophils
P gingivalis
Chronic periodontitis
** gingipain - protease cleaves host
T denticola
ANUP/ANUG
