  1. caries is _____, _____, _____, ____ and _____ but not yet eradicated!
    • infectious
    • transmissible
    • communicable
    • preventable
    • controllable
  2. what starts the basic caries process?
    acidogenic bacteria
  3. what does acidogenic bacteria do?
    it is in the BIOFILM and it metabolizes the fermentable carbs that is INGESTED by the PT
  4. what are infectious organisms that colonize the teeth and help to form the dental biofilm through their ability to create a sticky environment for survival and multiplication
    streptococcus mutans
  5. what type of bacteria is most active during demineralization of cavity formation?
    streptococcus mutans
  6. what bacteria predominate the caries process
    lactobacillus
  7. what bacteria is active during progression of the cavity
    lactobacillus
  8. what are four fermentable carbs (Mrs. SU, Mr. GLU and their kids FRUC and STAR)
    • sucrose
    • glucose
    • fructose
    • cooked starch
  9. what are the names of the four acids produced during sugar digestion? (ACE and LAC had to FORM a PROP for a school play...yes that is the best I can come up with deal with it)
    • ACEtic
    • LACtic
    • FORMic
    • PROPionic
  10. what is the function of saliva?
    buffer acids and supply minerals to replace those calcium and phosphate ions dissolved from the tooth during mineralization
  11. saliva functions to _____ acids and supply _____ to replace those ____ and _____ ions dissolved from the tooth during mineralization. It is also a source of ____ trasport to tooth surfaces
    • buffer
    • minerals
    • calcium
    • phosphate
    • Fluoride
  12. what are the three mechanisms of fluoride?
    • inhibits demineralization
    • enahnces remineralization
    • inhibits bacteria in the biofilm
  13. fluoride ______ demineralization, _____ remineralization and ______ bacteria in the biofilm
    • inhibits
    • enhances
    • inhibits
  14. what % of reduction is due to water fluoridation?
    40-60%
  15. what is used in the process of caries detection?
    • adequate lighting
    • sharp eyes
    • blunt probes
    • tri syringe
    • bitewing radiographs or vertical bitewings
  16. what are the four stages of caries?
    • initial
    • early
    • white
    • cavitation
  17. during the early stages of caries they are generally _____
    invisible
  18. during the initial stage of the caries _____ ____ infect the tooth.
    mutans streptococci
  19. what stage is it when it is clinging to smooth tooth, creating biofilm producing acid from fermentable carbs, acid diffuses thru microchannels between enamel rods, dissolves tooth minerals and create subsurface lesions
    INITIAL
  20. what do you do for an early white area?
    exam w/air under bright light, smooth surface with blunt probe
  21. what happens if surfaces is broken during an early white area?
    further demineralization and prevent remineralization
  22. t/f during a late white lesion remineralizeation may still be allowed
    true
  23. what stage of caries is a definitive lesion?
    cavitation
  24. what is the process by which minerals of tooth structure are dissolved by organic acids produced from fermentable carbs by the acidoogenic bacteria
    demineralization
  25. what provides protective factors in promoting remineralizatioin?
    saliva and fluoride
  26. what are the 6 factors of caries risk for adults?
    • social history
    • medical history
    • use of fluoride
    • dietary habits
    • biofilm
    • clinical/oral
  27. what are the three factors for early childhood risk of ral disease
    • family factors
    • health considerations
    • dietary considerations
