- Structures of the periodontium are:
- Gingiva
- Periodontal Ligament
- Cementum
- Alveolar bone
- All of the above
- The oral mucosa consists of:
- The gingiva & hard palates are composed of what type
of mucosa?
- Specialized mucosa can be found on what oral
structure?
- Is the COL keratinized?
- Which keratinized gingival is located coronal to CEJ
and surrounds tooth in a cuff like manner?
- What occupies the embrasure?
- Attached Gingiva is keratinized, and attached firmly
to bone. Tightly connected to cementum on cervical 1/3 of the root &
periosteium of alveolar bone. What does it lie between?
- What are the boundaries of the gingival sulcus:
- The gingival sulcus is lined with what kind of
epithelium?
- Covers the outer surface of the free gingival &
attached gingival: it extends from the crest of the gingival margin to the
mucogingival junction, keratinized or para keratinized stratified squamous
epithelium.
- Not as thick as outer epithelium, epithelial lining of
gingival sulcus extends from crest of gingival margin to coronal edge of
junctional epithelium. Lining the pocket. Non-keratinized stratified
epithelium without rete pegs.
- Not as thick as outer epithelium, separates PDL from
oral environment, determines the base of pocket, most coronal. Forms the
base of the sulcus & joins the gingival to the tooth surface (epithelial
attachment). Thin non-keratinized stratified squamous epithelium.
- Gingival connective tissue is also known as:
- Definition of above:
|
Gingival Fibers/ Supragingival fiber bundles |
A. Embedded in cementum near the CEJ & fan out into
the gingival connective tissue. |
|
Gingivodental fibers |
B. Pass from cementum of one tooth over the crest
of alveolar bone to the cementum of the adjacent tooth. Connect adjacent
teeth to one another & secure their alignment in dental arch. |
|
Circular Fibers |
C. Rope like collagen fiber bundles located coronal
to crest of alveolar bone. Provides rigidity to tissue. |
|
Transseptal Fibers |
D. Encircle tooth, coronal to alveolar crest & are
not attached to cementum, connect adjacent teeth to one another. |
- Secrete collagen:
- Is gingival fluid increased or decreased in disease?
- Which one of the principle fibers is only seen in
multi-rooted teeth?
- What fibers are not present in undeveloped, young,
unerrupted teeth?
- Which fibers resist horizontal pressure against the
crown of the tooth?
- The fibers that resist horizontal movement of the
tooth?
- These fibers resist vertical pressures that threaten
to drive root into its socket and are located apical to horizontal fibers.
- What are Sharpeys fibers?
- Bone Builders=
- Bone eaters, consumers =
- Create cementum =
- Alveolar bone supports & surrounds:
- Cortical bone:
- Cancellous bone:
- Cancellous bone is covered by:
- What is the bony socket, cavity that houses the root:
- Outline of socket:
- Where is the Alveolar crest located in health &
disease:
Health
Disease
- What area of bone lies between the proximal surfaces
of 2 adjacent teeth?
- Interradicular bone is found only in what?
- A window like defect in cortical bone resulting in an
isolated area of root that’s not covered by bone:
- Cleft like defect in the cortical bone including bone
margin:
- Where is bone resorbed?
- Where is bone formed?
- Cementum:
- 1st formed, uncalcified cementum:
- Masses of cementum:
- What % meets at the CEJ?
- What % overlaps the enamel?
- What % has a small gap between the enamel and cementum?
