19
Q

The ____ arteries anastomose with the PSA, MSA, ASA, IA, Mental, GP, and SL arteries

Interdental alveolar

20
Q

Cementum is ____ tissue

A

Mesenchymal

21
Q

The first cementum to be formed is ____ cementum

A

Acellular

Forms before the tooth erupts

22
Q

Cellular cementum is formed ____

A

After the tooth reaches the occlusal plane

23
Q

Cellular cementum differs from Acellular cementum in that it is/has:

A

Cells in lacunae
Less calcified than acellular cementum
Fewer Sharpey’s fibers than acellular cementum

24
Q

Cementum permeability ____ with age

A

Decreases

25
Q

Cementum formation is most rapid in the ____ region

A

Apical

26
Q

Cementum is thicker of the ____ than the ____

A

Distal than the Mesial

27
Q

Cementum thickness ____ with age

A

Increases

28
Q

Paget’s disease may correspond to ____

A

Hypercementosis

29
Q

The origin of cementum:

A

HERS disintegrates
Cementoblast differentiation
Cementoid deposition
Mineralization (begins at CEJ, moves apically)

30
Q

Cementum and Recession

A

Apical migration of the JE

Cementum exposed, is permeable, and penetrated by bacteria

31
Q

Which root fractures are repairable?

A

Horizontal root fractures, as long as they are not exposed to the oral cavity
Vertical root fractures are exposed to the oral cavity and are thus non-repairable

32
Q

A 
Alveolar bone
(Resorption and formation constantly occurring)
33
Q

The Alveolar process is a ____ structure

A

Tooth-dependent

Disappears after tooth loss

34
Q

Q

Bundle bone contains ____

A

Sharpey’s fibers

36
Q

Cancellous bone contains ____

A

Trabeculae (irregularly shaped marrow spaces)

37
Q

The Periosteum is ____

A

Layers of differentiated osteogenic CT

38
Q

The interdental space is the ____

A

Narrow space between the teeth

39
Q

Window

The tooth is covered by periosteum and gingiva

40
Q

A Dehiscence is a ____
