  1. The free gingival groove corresponds to the depth to the apical border of the ?
    Junctional epithelium
  2. 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
  3. Attached gingiva is found between the:
    Alveolar mucosa and the marginal gingiva
  4. 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:
    Junctional epithelium
  5. epithelium] is loosely packed with few desomosomes so white blood cells can permeate it.
    Junctional Epithelium
  6. Which of these is NOT a feature of periodontitis?
  7. The presence of large amounts of calculus in the gingival sulcus may be expected to:
    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
  8. 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? [answer]
    Ginigval crevicular fluid
  9. The MOST superficial part of the marginal gingiva in a healthy situation is called? [answer]
    Free gingival crest
  10. Marginal gingiva lacks stippling due to its lack of a mucoperiosteum.
  11. The epithelium covering the col consists of the [answer] of the adjacent teeth.
    marginal gingiva
  12. Together the sulcular epithelium and junctional epithelium form the [answer]
    Dentogingival junctional tissue
  13. 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
  14. Which part of the ginigval tissues is MAINLY involved in gingival hyperplasia?
    interproixmal gingiva
  15. Which of the following is the correct term for an inferiorly placed margin of free gingival crest?
    ginigval recession
  16. Which of the following medications are recognized as contributing to the abnormal overgrowth of gingival tissue? 
    Phenytoin sodium
