  1. what carious lesion begins as subsurface demineralization; acid from bacterial action on the tooth surface passes through microchannels in the enamel, demineralization occurs, and eventually a white spot can be seen clinically
    incipient
  2. true or false. The use of fluoride can help reduce incipient caries.
    true
  3. Are food particles neede in the mouth for biofilm to form?
    no
  4. Certain microorganisms and their toxic products can cause periodontal infectious diseases, where are these microorganisms found?
    in biofilm
  5. Where do the pathogens that can cause periodontal infections exist?
    in biofilm
  6. _________ provides protection and gives the organisms that cause periodonatl infections increased resistance to antibiotics
    biofilm
  7. there is a majority of aerobic, gram-positive organisms, and the number of organisms and white blood cells is relatively low in what type of pocket?
    healthy sulcus
  8. In what type of pocket is there more leukocytes, rods, spirocetes, and more activity?

    materia alba
  13. true or false. surface bacteria in contact with the gingiva contribute to gingival inflammation. tooth surface demineralization and dental caries are seen frequently under materia alba
