  1. substances with cleaning and polishing properties utilized in the formulation of a dentifrice to be compatible with fluoride compounds and other ingredients and not alter the tooth structure unfavorable
    abrasive system
  2. producing acid or acidity
    acidogenic
  3. a group of minerals of the general formula Ca10(PO4)6X2 wherein the X might included hydroxyl (OH) carbonate (CO) fluoride (F) or oxygen (O), crystalline mineral component of hard tissues
    apatite
  4. Ca10(PO4)6(OH)2 the form of apatite that is the principal mineral component of teeth bones and calculus
    hydroxyapatite
  5. the form of hydroxyapatite in which fluoride ions have replaced some of the hydroxyl ions with fluoride, the apatite is less soluble and therefore more resistant to acids formed from carbohydrate intake
    fluorapatite
  6. apatite formed when low concentrations of fluoride react with tooth mineral; at higher concentrations calcium fluoride is formed
    fluorhydroxyapitite
  7. exposure of a tooth surface to an acid attach; acid is from the action of dental biofilm and cariogenic food ingestioin
    cariogenic challenge
  8. exerting an inhibitory action on the progress of dental caries
    cariostatic
  9. lowering the amount of fluoride in fluoridated water to an optimum level for the prevention of dental caries and dental fluorosis
    defluoridation
  10. breakdown of the tooth structure with a loss of mineral content, primarily calcium and phosphorus
    demineralization
  11. with reference to a product an efficacious product produces a statistically and clinically significant benefit under ideal testing conditions in carefully controlled clinical trials
    efficacy
  12. a salt of hydrofluoric acid occurs in many tissues and is stored primarily in bones and teeth
    fluoride
  13. form of enamel hypomineralization due to excessive ingestion of fluoride during the development and mineralization of the teeth; depending on the the length of exposure and the ppm of the fluoride the area may appear as a small white spot or as severe brown staining with pitting
    fluorosis
  14. semisolid or solid phase of a colloid solution
    gel
  15. process by which sugar is metabolized by bacteria to produce acid
    glycolysis
  16. deficient calcification
    hypocalcification
  17. defect of enamel maturation caused by hereditary or systemic irregularities
    enamel hypocalcification
  18. occurs when foods and beverages processed in a fluoridated community are imported and consumed in a nonfluoridated community
    halo or diffusion effect
  19. stage or process of becoming mature or attaining maximal development with respect to tooth development, it results from the continuous dynamic exchange of ions into the surface of the enamel from pellical, dental bioflim and oral fluids
    maturation
  20. over the counter
    OTC
  21. parts per million; measure used to designate the amount of fluoride used for optimum level in fluoridated water, dentifrice, and other fluoride containing preparations
    ppm
  22. restoration of mineral elements in a tooth surface enhanced by presence of fluoride; remineralized lesions are more resistant to initiation of dental caries than is normal tooth structure
    remineralization
  23. demineralized area below the surface of the enamel created by acid that has passed through micropores between enamel rods subject to remineralization by action of fluoridee
    subsurface lesion
  24. type of gel that sets in a gel like state but becomes fluid under stress the fluid form permits the solution to flow into interdental areas
    thixotropic
  25. term used to describe a small area on the surface enamel that contrasts in appearance with the rest of the surface and may be visible only when the tooth is dried; two types of these can be differentiated an area of demineralization and an area of fluorosis
    white spot
