t/f caries is infectious, transmissible, communicable, and preventable (not yet eradicated)
true
what is the most active during INITIAL stages of demineralizations and cavity formation?
streptococcus mutans
what are the two types of acidogenic bacteria in this module we talk about with caries?
strep mutans
lactobacillus
which acidogenic bacteria is only active in the ADVANCED lesions for the progression of the cavity?
lactobacillus
what are 4 types of fermentable carbs?
sucrose
glucose
fructose
cooked starch
t/f frequency determines the amount of acid produced and the extent of tooth destruction
true
acid production (4)
acetic
lactic
formic
proprionic
what is used to balance or reverse the destruction of the tooth structure?
saliva
what buffers acids and supplies minerals to replace calcium and phosphate ions dissolved from the tooth during mineralization?
our wet friend saliva!
what is a continued source for fl2 from all of its contacts?
saliva again!
what are the three mechanisms of fl2?
inhibits demineralization
enhances remineralization
inhibits bacteria in the biofilm
____-____% is reduction of caries due to water floridation
40-60%!!!!
in order to detect caries, what 4 items are needed (and used if you are a good clinician)?
adequate lighting
sharp eyes
blunt probe
tri-syring for viewing wet
what is a tri-syringe for?
visual exam
instrumental
radiograph
( i dont get this ) what is a tri syringe!?
which caries stage is infected by mutans strep, subsurface lesion, casued by bacteria clinging to smooth surfaces between microchannels, disolves tooth minerals, but can be mineralized?
initial
if caries is generally invisible, this is what stage?
early subsurface infection
a smooth surface that shouldnt be poked can be remineralized with fluoride. what stage is this?
white area lesion, later stage
when is the plan to appoint for restoration? which stage of caries?
cavitation, definitive lesion
saliva and fl2 provide protective factors to halt or arrest the demineralization process. what is this called?
remineralization
what is the process by which the minerals of the tooth structure are dissolved by the organic acids produced from the fermentable cabs bay the acidogenic bacteria?
demineralization
what are risk factors for caries?
habits
behaviors of life styles or conditions that when present increases the probability of a disease occurring
