Cariology Flashcards
Dental caries lesions are
lesions that occur due to activity within plaque that covers a tooth
pH that starts to dissolves enamel
5.5 or lower
when the biofilm is left undisturbed
for any period of time, a caries lesion may form
best definition of dental caries lesions
a multi-factorial process of decriminalization and concurrent remineralization, and are often reversible
the effect of metabolic processes within a community of microorganisms that
work together FOR THEIR OWN BENEFIT

Agent factors

- S. mutans
- S. sobrinus
- Lactobacilli
- other pathogens
Host factors
-tooth (anatomy)
Saliva quantity
Saliva quality
Immune responses
Environment factors
dietary fermentable carbohydrates
Another term for describing the results and symptoms of dental carie
localized chemical dissolution of the tooth surface caused by metabolic events taking place in the biofilm covering the affected area
Streptococcus mutan is gram
positive
what is the primary causative agent in the formation of dental cavities
Strep mutans
strep mutans are able to
metabolize sucrose to lactic acid
rate of caires depend on
frequent of intake oral hygen saliva microbes tooth surface host denfense
enamel facts
ectoderm orgin
avascular
acellular
cannot repair itself
emamel ismade up of
95% mineral
5% water
long, thin cystallites of hydroxyapatite or carbonated apatite
once erupted, enamelis in
dynamic trasformation
Dentin is
mesodermal orgin 75% inorganic 25% organic 5% water reparative mechanism (odontoblasts) works in concert with pulp (dentino-pulpal organ)
types of dentin
primary-forms before eruption
secondary-form through root formation
tertiary-forms in response to stimuli from bi-products of bact infections
