histoolgy chapter 10-gingival and dentogingival junctional tissue

  1. epithelial tissue covering the alveolar process
  2. gingiva tightly adheared to bone around the roots of the teeth
    attached gingiva
  3. extension of attached gingiva between adjacent teeth
    interdental gingiva (interdental papilla)
  4. unattached band of tissue that encircles the neck of the tooth
    marginal gingiva (free gingiva)
  5. gingiva that faces the tooth
    dentinogingival jusctional tissues
  6. interdental gingiva that is apical to the contact area-concave form-mainly seen between posterior teeth
  7. is the most important tissue to the dental hygienist-provides a barrier to periodontal damage and disease
    gingival tissue
  8. smae as the gingivial margin-easily seen and is an important part of the clinical exam
    free gingival crest
  9. mostly pink-firm and immobile with stippling-width varies
    attach gingiva - in heath
  10. fill the area between the teeth to prevent food impaction-conical in anterior and more blunted in the posterior area
    interdental papilla
  11. similar to the attached gingiva in appearance-lacks stippling and is more mobile-.5-2mm in width
    marginal gingiva-in health
  12. separates the attached gingiva from the marginal (free) gingiva-corresponds to the ase of the sulcus -most prominent in lower anterior and premolar areas
    free gingival groove
  13. firm and immobile - thick layer of paarakeratinized epithelium-interface between epithelium and lamina propria is highly interdigitated
    attached gingival
  14. firm but moile-keratinized stratified squamous epithelium-
    marginal gingiva
  15. junction between tooth surfaces and gingival tissue
    dentinogingival junction
  16. sulcular epithelium and junctional eptihelium together
    dentinogingival junctional tissues
  17. narrow space between tooth and sucular epithelium-normally .5-3mm deep
    gingival sulcus
  18. fills the gingival sulcus and includes WBC and antibodies
    seeps between dpithelial cells into sulcus
    passes form sulcus into the oral cavity
    gingival (crevicular) fluid
  19. lines the floor of the sulcus-attaches to tooth surface on enamel, cementum, or dentin
    junctional epithelium
  20. sulcular eptihelium is nonkeratinized stratified squamous epithelium
  21. the interface between the epithelium and lamina propria is fairly smooth on this type of epithelium
    sulcular epithelium
  22. differs form other types of oral epithellium in several ways
    loosely packed cells with fewer desmosomal junctions
    more intercellular space
    increased flow of WBC from lamina propria
    junctional epithelium
  23. thinner than other tissue, but forms strong seal between gingiva and tooth surface
    rapid rate of mitosis
    junctional eptihelium
  24. cells remain immature
    have many more organelles
    junctional eptihelium
    organelles of the junctional epithelium
  26. cell renewal in dentinogingival junctional tissues
    • 1. new cells form in basal or deepest layer
    • 2. cells migrate coronally-parallel to tooth
    • 3. highest renewal rate in oral cavity-4-6 days
  27. junction between the tooth surface and the gingival tissues
    dentogingival junction
  28. stands away from the tooth creates the gingival sulcus
    sulcular epithelium
  29. space tht is filled with gingival fluid(crevicular fluid)
    gingival sulcus
  30. depth of the marginal tissue
