week 12 Flashcards
dysbiosis definition
and 2 ways it can occur
a microbial imbalance
overall loss of microbial diversity
and
when beneficial organisms are lost and potentially harmful organism increase
Early colonization and high levels associated with early childhood caries leads to
a more severe expression of disease
Non-colonization of S. mutans in infants most significantly associated with x because it (2)
parent assisted tooth brushing because it
- physical disrupts biofilm
- creates oral health awarness
Ecological Plaque Hypothesis
plaque mediated diseases are consequences of microflora imbalnces that come from enrichment of pathogens in microbial community
Fungal species that enhances cariogenic biofilm virulence, especially in early childhood caries (ECC)
Candida Albicans
Health-associated organism can counter the low pH produced by acidogenic organisms by using
arginine or urea to generate ammonia.
Streptococcus Mutans immunoassay
detects SM levels and antibodies to SM in the saliva
with 2 tone disclosing
pink will be x
blue will be x
Thin, immature biofilm = PINK
Thick, mature biofilm = BLUE
with tri plaque id gel
pink will be x
dark blue/purple will be x
light blue will be x
Thin plaque = PINK
Old plaque – non-fermenting =DARK BLUE/purple
Old plaque - fermenting=LIGHT BLUE
Old plaque - fermenting
light blue
acid production from plaque/biofilm is about pH 4.5 or lower
Old plaque – non-fermenting
dark blue/purple
areas that have not bean cleaned for 48 hours +
has complex biofilm
thick plaque that causes gingivitis
prebiotic agents can
reprogram behavior of plaque
sugar-free topical crème demonstrated that suppress the emergence of Streptococcus Mutans and lower the production of acidic substances
