Yes
Does the interdental papilla have keratin?
Yes

The PDL is made of what type of fibers, and what is it not made of?
It is made of collagen fibers, and not elastic fibers
What is the width of the PDL?
0.25 mm
What are PDL fibers shaped like? And what are they not?
They are wavy, not straight
T/F Oblique fibers of the pPDL are inserted in the alveolar bone at a more apical level than in the cementum
False-the oblique fibers are more apical at the cementum than the alveolar bone
Where are Sharpey’s fibers found?
They are part of collagen fibers found in bone/cementum
What is the bundle bone?
The part of the alveolar process where Sharpey’s fibers are present
What is an example where pink gingiva does not mean healthy gums?
Fibrosis
Why is the alveolar mucosa redder than gingiva?
There is keratin in the gingiva
