  1. pulp is formed from the _______ _________ of the dental papilla, which came from the __________ MESODERM
    • central cells
    • ectomesenchyme
  2. why is the pulp involved in the formation of dentin?
    because the ondontoblasts live in the outer layer of the pulp
  3. the pulp has a sensory function because the nerve _______ _______ are located in the ______ layer of the pulp
    • cell bodies
    • outer
  4. the pulp is the nutritional function for the dentin through the _________
  5. what is the pulps protective function?
    secondary is formed from the ondontoblasts in the outer layer of the pulp
  6. what are the five anatomy parts of the pulp?
    • pulp chamber
    • coronal pulp/horns
    • radicular pulp
    • apical foramen
    • accessory canals
  7. the mass of the pulp in the middle, follows the sape of the tooth
    pulp chamber
  8. the pulp in the crown area
    coronal pulp
  9. smaller extensions of the coronal pulp into the crown are:
    pulp horns
  10. the pulp in the root areas. it has an opening through the dentin and cementum, out to the surrounding periodontal ligament
    radicular pulp
  11. the opening of the pulp into the periodontal ligament, usually at the very apex of the tooth. allows arteries, veins, ________ and nerves to enter the tooth
    • apical foramen
    • lymphatics
  12. extra opening from the pulp to the periodontal ligament
    accessory canals
  13. accessory canals usually run _________ to the root of the tooth
  14. accessory canals occured because:
    HERS ran into a blood vessel while it was forming so it just formed a little canal around the vessel.
  15. do endodontists like accessory canals?
    not bloody likely!
  16. pulp is a ________ tissue, so ti is mainly full of _________
    • connective
    • fibroblasts
  17. the pulp also has ondontoblasts and ______ _______ cells
    white blood
  18. what contains collagen fibers and an extensive vascular supply?
    the pulp striggity!
  19. these may be present in the pulp. calcified masses of dentin inside the pulp chamber
    pulp stones
  20. these only cause problems during endodontic therapy:
    the dang calcified dentin, pulp stones
  21. inflammation of the pulp
  22. pulpitis may be caused by _________ caries, ________ preparation, or traumatic injury
    • extensive caries (MOST COMMON!)
    • cavity
  23. a channel that forms in the bone or soft tissue to rain infection
  24. does a fistula hurt?
    no, it is draining so there is no pressure
  25. pressure from pulpitis can be relieved by _______ and drainage or a ________
    • incision
    • fistula
  26. inflammation of the pulp can exit through the ________ ________ and cause an _______
    • apical foramen
    • abcess
  27. what must be done to save a tooth with pulpitis?
    our good friend root canal
  28. T/F without the pulp, the tooth becomes brittle and more prone to breakage
    true true!
  29. T/F drilling can cause trauma to a tooth and result in a root canal
  30. gutta percha is from:
    a gutta percha tree (rubber) the body accepts it
  31. what needs to be done after a root canal for the long term success of a tooth?
    your tooth gets to be a queen and wear a crown!
  32. do anterior teeth always need to be crowned after a root canal?
    not always, more for aesthetic purposes, tooth will darken
