  1. how much microorganisms in saliva per milliliter?
    750 million
  2. Disease of the oral mucosa and tissues?
    abcess

    cyst

    ulcer
  3. abcess
    localized collection of pus, commonly caused by bacterial infection.
  4. Cyst
    enclosed pouch or sac containing fluid or semi-solid material
  5. ulcer
    disruption of the superficial covering of mucosa or skin
  6. Vesicles
    small elevation that contains fluid

    leaves superficial ulcers upon rupture
  7. hematoma
    localized collection of blood 

    well defined and turns a dark color with tie
  8. lesions above the surface
    vesicles

    hematoma
  9. non-elevated lesions
    petechiae

    ecchymoses
  10. petechiae
    pound, pinpoint non-raised, purplish-red spots caused by mucosa or dermal hemorrhage
  11. ecchymoses
    large, purplish red areas caused by blood under the skin or mucosa

    turns a blue to yellow color
  12. diseases of the tooth and gingiva
    dental caries

    pulpalgia

    pulpitis

    periapical abcess

    necrosis
  13. dental caries
    caused by streptococci

    first appears as chalky whit spots on enamel(incipient)

    indicates decalcification 

    arrested if it dosent continue, will be dark and hollowd out
  14. recurrent dental caries
    when a dental caries occurs where there is already a restoration.
  15. pit and fissure caries
    Develops in depressions of tooth surfaces
  16. smooth caries
    usually on the proximal surface
  17. pulpalgia
    pain in the dental pulp

    short sharp shooting pain that's worse when lying down or climbing stairs
  18. pulpitis
    inflammation of the dental pulp

    results from dental bacterial infection or a fractured tooth

    dull ache that can progress to severe, pulsating pain
  19. periapical abcess
    pulp becomes inflamed

    smells pus-like

    ulcers form in pulpal canal, can spread to the bone

    tooth feels "high" when biting, sensitive to the touch
  20. necrosis
    death of the tissue

    may not be in any pain

    smells foul, rotten
  21. what is the MOST prevalent disease in mankind?
    Periodantal
  22. periodontal disease
    bleeding with brushing, tender, red swollen gums, tooth shifting, tooth elongation, mobile teeth, purulent exudates in between teeth, halitosis.
  23. Gingivitis
    inflammation of the gingival tissue
  24. Marginal gingivitis
    most common gingival disease

    starts at the tip of the papillea, results in swelling and loss of texture, easy bleeding.
  25. Necrotizing Ulcerative Gingivitis (NUG)

    AKA trenchmouth, Vincent's infection
    redness, swelling, px, accumulation of calculus, bleeding, film and necrotic (white) tissue that can be wiped off leaving a raw red wound.

    ulceration leaves a punched out appearance of gingival crest 

    unpleasent odor and foul taste
  26. Periodontitis
    Chronic inlammatory condition involving gingival, periodantal membrane and alveolar bone

    results in loss of bone, periodantal pocket formation, increases tooth mobility

    gingival becomes bluish red
  27. periodontal pocket
    inflammation forms at the apex of the tooth

    Gingiva bleeds easily, calculus forms shelf-like projection

    interdental papillae is destroyed 

    results in loss of teeth
  28. periodontal abcess
    results from long, continuous irritation.

    surrounding gingival becomes inflamed and swollen
  29. pericoronitis
    inflammation of gingival around a partially erupted tooth

    most common with wisdom teeth

    gingival flap may become infected
  30. recurrent apathous stomatitis (RAS)
    canker sores, painful ulcerations

    seven to ten day healing time
  31. Herpes Simplex
    type 1 is oral

    type 2 is genital
  32. Oral manifestations of HIV
    Candidiasis

    Hairy Leukoplakia

    Kaposis Sarcoma
  33. Candidiasis
    fungal, red or white in color
  34. Hairy leukoplakia
    viral tongue infection

    white, slightly raised lesions
  35. atrition
    loss of substance of a tooth from a wearing away process caused by teeth against teeth
