  1. a secondary canal extending canal extending from the pulp to the surface of the root; frequently found near the apex of a root but may occur higher and provide a connection to a perio pocket
    accessory root canal
  2. production and development of enamel
    amelogenesis
  3. dentition that begins in utero
    primary
  4. primary teeth are being exfoliated and permantent teeth come in 6-12 years old
    mixed dentition
  5. mineralization begins at birth and continues into adolescenece
    toots are complete usually by 3 years after eruption
    permanent teeth
  6. the tearing away or forcible separation of a structure or part.
    avulsion
  7. an oral habit of grinding, clenching, or clamping the teeth;
    bruxism
  8. conducive to dental caries
    cariogenic
  9. used to define a carious lesion
    carious
  10. a calcified spherical body composed of cementum, lying free within the pdl, attached to the cementum or imbedded within the cementum
    cementicle
  11. disease of mineralized structures of the teeth characterized by demineralization of the hard components and dissolution of the organic matrix
    dental caries
  12. carious lesion that has become stationary and does not show a tendency to progress further; frequently has a hard surface and takes on a dark brown or reddish-brown color
    arrested caries
  13. occures on surfaces not previously affected; also called initial caries; early lesion may be referred to as incipient caries
    primary caries
  14. widespread formation of chalky white areas and incipient lesions that may increase in size over a comparatively short time
    rampant caries
  15. occures on a surface adjacent to a restoration; may be a continuation of the original lesion; also called secondary caries
    recurrent caries
  16. the natural teeth in a dental arch
    dentition
  17. the permanent teeth that erupt into the positions of exfoliated primary teeth
    succedaneous
  18. what pH does cementum demineralize
    6.0-6.7
  19. what pH does enamel demineralize
    4.5-5.5
  20. the pH at which demineralization occures
    critical pH
  21. localized, post-eruptive, pathologic process of external origin involving softening of the hard tooth tissue and proceeding to the formation of cavity
    dental caries (WHO)
  22. what are the requirements for the development of a cavity (6)
    • microorganisms
    • biofilm
    • carb
    • susceptible tooth surface
    • strepococcus mutans
    • lactobacillus
  23. involves one tooth surface
    simply cavity
  24. involves two tooth surfaces
    compound cavity
  25. involves more than two tooth surfaces
    complex cavity
  26. what are the steps of the formation of cavities
    • phase I (incipient (enternal))
    • Phase II (white marks)(untreated incipient)
  27. what are the three root caries
    • cemental caries
    • cervical caries
    • radicular caries
  28. steps in root caries
    • 1. gingival recession
    • 2. begins near CEJ
    • 3. enamel not envolved
    • pH cementum 6.0-6.7
    • pH enamel 4.5-5.5
  29. clinical recognition of root caries
    cavitated lesions are soft leathery or hard
  30. wearing away of a tooth as a result of tooth-to-tooth contact
    attrition
  31. what is caused from aggressive brushing
    abrasion
  32. what is caused from to much acid
    erosion
