The flashcards below were created by user anatomy2012 on FreezingBlue Flashcards. What would you like to do?


  1. Be able to label parts on the diagram

    gingival sulcus, marginal gingiva, free gingival groove(marginal groove), attached gingiva, mucogingival junction, alveolar mucosa
    these are in the order to answer the diagram labeling
  2. The free gingival groove corresponds to the depth to the apical border of the ?

    Junctional epithelium
    Gingival sulclus
    Free gingival crest
    Junctional epithelium
  3. What gingival tissue is an extension of attached gingiva and fills in the area between the teeth apical to their contact areas to prevent food impaction?
    Interdental papillae
  4. Attached gingiva is found between the:

    Mucogingival junction and the free gingival groove
    Alveolar mucosa and the marginal gingiva
    Marginal ginigva and free gingival groove
    Teeth of the dentition
    Mucogingival junction and the free gingival groove
  5. Match the following six (6) terms with their descriptors:

    1 Marginal gingiva has a surface layer of what kind of epithelium?

    2 Junctional epithelium

    3 The type of epithelium related to the col

    4 free gingival groove

    5 sulcular epithelium

    6 attached gingiva has a thick layer ofmainly what type of eithelium?

    stratified squamous epithelium either non-keratinized or parakeratinized  with it’s cells tightly packed

    superficial layer does not show any cellular changes releated to maturation like keratinaized tissue

    separates the attached gingival from the marginal gingiva

    Orthokeratinized stratified squamos epithelium

    parakeratinized stratified squamous epithelium

    non-keratinized epithelium
    • Orthokeratinized stratified squamos epithelium
    • superficial layer does not show any cellular changes releated to maturation like keratinaized tissue
    • non-keratinized epithelium
    • separates the attached gingival from the marginal gingiva
    • stratified squamous epithelium either non-keratinized or parakeratinized  with it’s cells tightly packed
    • parakeratinized stratified squamous epithelium
  6. After the tooth crown has emerged into the oral cavity, the part of the reduced enamel epithelium  (REE) which remains near the CEJ after the tooth erupts is hencefortpart referred to as the:

    Gingival epithelium
    Marginal gingiva
    Junctional epithelium
    Enamel cuticle
    Junctional epithelium
  7. [epithelium] is loosely packed with few desmosomes so white blood cells can permeate it
    junctional epithelium
  8. Which of these is NOT a feature of periodontitis?

    Bleeding on probing
    Furcations may be present
    Reversible
    Teeth may be mobile
    reversible
  9. The presence of large amounts of calculus in the gingival sulcus may be expected to: 

    Damage the epithelium of the gingival sulcus, cause resorption of the root apex, and cause
    formation of excessive cementum at the apex

    Damage the gingival group of periodontal ligament fibers, produce additional dentin
    formation beneath the periodontal ligament, and produce inflammation of the gingival tissue

    Damage the epithelium of the ginigval sulcus, produce inflammation and swelling of the surrounding gingiva, damage the fibers of the periodontal ligament in the inflamed area, and result in resorption of the bone of the alveolar crest

    Produce inflammation of the gingival tissue, produce pulpitis beneath the calculus, and result in resoprtion of the bone of the alveolar crest
    • Damage the epithelium of the ginigval sulcus, produce inflammation and swelling of the surrounding gingiva, damage the fibers of the
    • periodontal ligament in the inflamed area, and result in resorption of the bone of the alveolar crest
  10. What contains both the immunological components and cells of the blood; also contains sticky plasma proteins in the sulcus that serve as adhesive for its lining tissue, keeping it in contact?
    gingival crevicular fluid
  11. The MOST superficial part of the marginal gingiva in a healthy situation is called?
    free gingival crest
  12. Marginal gingiva lacks stippling due to its lack of a mucoperiosteum.

    True
    False
    true
  13. The epithelium covering the col consists of the [answer] of the adjacent teeth
    marginal gingiva
  14. Together the sulcular epithelium and junctional epithelium form the ________
    dentogingival junctional tissue
  15. The Junctional epithelium is attached to the tooth surface by the way of the [answer] which acts as a type of seal between the soft gingival tissue and the hard tooth surface
    epithelial attachment
  16. Which part of the ginigval tissues is MAINLY involved in gingival hyperplasia?

    interproixmal gingiva
    free gingival groove
    facial and lingual gingival tissue
    mucogingival juncytion
    interproixmal gingiva
  17. Which of the following is the correct term for an inferiorly placed margin of free gingival crest?

    gingival hyperplasia
    gingival sulcus
    ginigval recession
    gingival tissue
    ginigval recession
  18. MULTIPLE ANSWERS

    Which of the following medications are
    recognized as contributing to the abnormal overgrowth of gingival tissue?

    Phenytoin sodium
    Cyclosporines
    Calcium Channel blockers
    Antihistamines
    • Phenytoin sodium
    • Cyclosporines
    • Calcium Channel blockers
  19. Of the tissues in the entire oral cavity, the ______  has the highest cellular turnover time, which is ______ days.
    • junctional epithelium
    • 4-6 days
