  1. What is epidemiology use for?
    • provides info on the processes and on the disease
    • identifies populations at risk or in need of services
    • tests preventive interventions for controlling disease
    • evaluates effectiveness and quality of interventions and programs
  2. What does epidemiology compares?
    • regions and environments
    • social factors and access
    • similarities and differences
  3. Epidemiology of community...
    • survey
    • analysis
    • program plan
    • program operations
    • $ for programs
    • appraisal
  4. what is the epidemiology of patient?
    • examination
    • diagnosis
    • treatment plan
    • treatment
    • $ for treatment
    • evaluation
  5. what is index?
    • standard method of rating on a scale
    • plural = indices
  6. What are the types of measurement?
    • ordinal: good/fair/poor
    • nominal: arbitrary scales (grade)
    • interval/ ration: percentages, x out of y
    • irreversible: survival data
    • reversible: remineralization?
  7. To get relevant, accurate, meaningful data, what can you do?
    • survery methods
    • standardization
    • disease definitions
    • detection methods
  8. What is valid?
    it measures what it says it measure
  9. what is reliable?
    • repeatable
    • reproducible
    • consistent at any time under a variety of conditions
  10. ideal index requires both what?
    validity and reliability
  11. Define prevalence.
    caries at one point in time
  12. what is incidence?
    individual experiencing new caries in a specific time period
  13. what are trends?
    change of differences in prevalence or incidence over time, or location, or socioeconomic.
  14. what are the dental indices?
    • Permanent: DMFT = 0-28 or DMFS = 0=128
    • Primary: deft = 0-20 or defs = 0-88
    • posterior - 5 surfaces
    • anterior - 4 surfaces
    • exclusion for 3rd molars
  15. what is the limitation of the dental indices?
    • not useful for identifying treatment needs
    • indices don't account for sealted teeth
    • indices don't relate to teeth at risk
    • gives equal weight to missing, untreated, or well-restored teeth
    • don't account for teeth lost for other reasons (ortho or perio disease)
  16. what are the exclusions for the dental indices?
    • 3rd molars
    • unerupted teeth
    • congenitally missing or supernumeray teeth
    • teeth lost not to caries
    • retained primary teeth
  17. What is NHANES ?
    National Health and Nutrition Examination Survey
  18. What are the decay patterns of permanent teeth?
    • 5 x occlusal caries = interproximal (MD)
    • 2.5 x BL caries = interproximal (MD)
  19. what is the decay pattersn of primary teeth?
    • occlusal caries = interproximal
    • only slightly greater than BL
  20. DMF ______ with age because people are missing more teeth.
    Females have greater DMF scores because ______.
    • increases
    • they seek treatment more
  21. about ______% of ppl greater than 18 yrs old exhibit root caries.
    25%
  22. root caries lesions increase/decrease with age, related to root exposure, medications, and numbers of retained teeth.
    increase
  23. What is ICDAS?
    • a system of caries detection/ assessment relfecting current scientific understanding of carious process
    • coronal caries
    • root caries
    • caries adjacent to restorations or sealants
  24. how to score an early carious lesion?
    • not yet cavitated
    • appears as a discolored fissure w/o loss of substance
    • white spot
    • radiographically an interproximal shadow
    • not all lesions progress to dentinal lesions
  25. cost of dental care is about _____% of total health care costs. (it is decreasing)
    use of fluoride have saved ______ between 1960 and 2000
    • 5%
    • $40 billion
