Week 4: Guest Lecturer- Orthodontics

Question 1

Where could bone remodelling occur when talking about teeth?

Answer 1

Could be around the erupting tooth. Drive the tooth and come to the oral cavity

Question 2

What is one possible source of tooth eruption?

Answer 2

Peridontal ligaments

Crowding of the tooth

Question 3

Where is most strain in the mouth?

Answer 3

1. Peridontal ligament

2. Dental follicular tissue

Question 4

Which part of the tooth experiences more tension and which part experiences more resorption?

Answer 4

Apical (bottom of tooth) experiences more tension

More resorption experienced at top (coronal side)

Question 5

Does bone formation and bone resorption occur in the tension or compression zones?

Answer 5

Bone formation occurs in tension zone

Bone resorption occurs in compression zone.

Question 6

What is cortication?

Answer 6

The bone response to altered distribution of force

Question 7

What type of force did the majority of the cyst capsule experience?

Answer 7

compression

Question 8

What is mechanobiology?

Answer 8

Changes due to forces WITHIN the cell

Question 9

Assuming we are using scaffold to simulate the extracellular matrix (ECM), what’s the gap of that to real life cell interaction?

Answer 9

Shear stress and the flow of fluid will affect the cells too, so look at using hydrogel (gel-like ) fluid which is more similar to cell niche.
With just changing the stiffness for the gel we can get the mechanical transition.

Question 10

Do you think dental tissue engineering is very accessible?

Answer 10

Yes but you still need to get patient consent, human ethics and such

Question 11

Example of hard and soft tissue

Answer 11

Hard Tissue: Enamel Dentin

Soft Tissue: Dental pulp

Question 12

what is front loading called?

Answer 12

Incision

Question 13

what is back loading called?

Answer 13

molar biting
