Back 17

alveolar (oral) mucosa

Front 18

What are the three zones the gingival epithelium can be divided up into?

Back 18

1. oral epithelium

What type of mucosa is the attached gingiva?

Back 25

keratinized

Front 26

The gingiva includes what three types of epithelium?

Back 26

1. oral epithelium
2. sulcular epithelium
3. junctional epithelium

Front 27

What is the name of the most coronal aspect of the gingiva?

Back 27

marginal gingiva

Front 28

Does the marginal gingiva attach to the tooth?

Back 28

no but it lies passively against it

Front 29

The space between the tooth and the marginal gingival is called?

Back 29

gingival sulcus

Front 30

What is the coronal edge of the marginal gingiva?

Back 30

free gingival margin

Front 31

What distinguishes the free gingival margin from the attached gingiva?

Back 31

the free gingival groove

Front 32

What is the free gingival groove?

Back 32

A slight depression on the coronal gingiva corresponding to normal sulcus depth

Front 33

What attaches the cementum to the alveolar bone by collagen fiber bundles? (sharpey's fibers)

Back 33

periodontal ligament

Front 34

What are the 4 functions of the periodontal ligament?

Back 34

1. sensation
2. holding the tooth in it's socket
3. cushioning of forces to the tooth
4. separation of the dentin from bone

Front 35

What is the name of the fibrous and cellular layer that covers bone and contains cells that become osteoblasts?

Back 37

stabilization of mobile teeth by attaching the teeth to nonmobile adjacent teeth

Front 38

What are the four indications for attempting periodontal splinting?

Back 38

1. To accompany the healing phase of periodontal therapy
2. For stabilization after trauma
