Biological Mediators

Question 1

These cells are responsible for making new PDL.

Answer 1

Fibroblasts

Question 2

When do you get a long epithelial attachment?

Answer 2

When the epithelial cells from the flap migrate downwards.

Question 3

Perio therapy to restore cementum, PDL, and alveolar bone what was lost from periodontitis.

Answer 3

Regeneration

Question 4

When we cut tissues away rather than regenerate them.

Answer 4

Resection

Question 5

Need this kind of closure when placing a graft or barrier membrane.

Answer 5

Primary (sutures)

Question 6

Excluding the epithelia while causing regeneration of the PDL and alveolar bone.

Answer 6

Guided Tissue Regeneration (GTR).

Question 7

What are barrier membranes a barrier to?

Answer 7

Gingival epithelium and CT from entering the site.

Question 8

What do barrier membranes allow into the site?

Answer 8

Fibroblasts and osteoblasts to form new CT and bone.

Question 9

In addition to barrier membranes, these are used to create a barrier from epithelial cells and CT cells.

Answer 9

Bone grafts

Question 10

Answer 10

Osteoconductive.

Question 14

Allows mesenchymal cells to morph into bone cells.

Answer 14

BMPs

Question 15

The only molecule that can TRANSFORM a mesenchymal cell to an osteoprogenitor cell.

Answer 15

BMP

Question 16

A commercial BMP

Answer 16

Infuse bone graft

Question 17

Term for this:

Localized alveolar ridge augmentation following extraction.

You extract the tooth and fill the hole with bone.

Answer 17

Socket preservation

Question 18

Poke some bur holes into the cortical bone to allow for bleeding, which makes the graft take to the bone.

Answer 18

Cortical penetration

Question 19

Mobility of the implant means it has lost this.
