  1. t/f caries is infectious, transmissible, communicable, and preventable (not yet eradicated)
    true
  2. what is the most active during INITIAL stages of demineralizations and cavity formation?
    streptococcus mutans
  3. what are the two types of acidogenic bacteria in this module we talk about with caries?
    • strep mutans
    • lactobacillus
  4. which acidogenic bacteria is only active in the ADVANCED lesions for the progression of the cavity?
    lactobacillus
  5. what are 4 types of fermentable carbs?
    • sucrose
    • glucose
    • fructose
    • cooked starch
  6. t/f frequency determines the amount of acid produced and the extent of tooth destruction
    true
  7. acid production (4)
    • acetic
    • lactic
    • formic
    • proprionic
  8. what is used to balance or reverse the destruction of the tooth structure?
    saliva
  9. what buffers acids and supplies minerals to replace calcium and phosphate ions dissolved from the tooth during mineralization?
    our wet friend saliva!
  10. what is a continued source for fl2 from all of its contacts?
    saliva again!
  11. what are the three mechanisms of fl2?
    • inhibits demineralization
    • enhances remineralization
    • inhibits bacteria in the biofilm
  12. ____-____% is reduction of caries due to water floridation
    40-60%!!!!
  13. 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
  14. what is a tri-syringe for?
    • visual exam
    • instrumental
    • radiograph
    • ( i dont get this ) what is a tri syringe!?
  15. 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
  16. if caries is generally invisible, this is what stage?
    early subsurface infection
  17. a smooth surface that shouldnt be poked can be remineralized with fluoride. what stage is this?
    white area lesion, later stage
  18. when is the plan to appoint for restoration? which stage of caries?
    cavitation, definitive lesion
  19. saliva and fl2 provide protective factors to halt or arrest the demineralization process. what is this called?
    remineralization
  20. 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
  21. what are risk factors for caries?
    • habits
    • behaviors of life styles or conditions that when present increases the probability of a disease occurring
