1

Grinding on its own causes little or no wear. You also need: 

Acid. 

2

Loss of posterior suport can increase attrition

True or false

False

3

What do you need to be cautious of when prescribing a splint for wearing at night? 

Does patient have an acid problem? Will pool. 

4

3 endogenous causes of erosion? 

  • Regurgitation
  • Psych issues eg bulimia
  • Saliva quality/quantity eg older patients - low buffering

5

4 exogenous causes of erosion

  • Diet and dietary habits
  • Medicines causing dry mouth (or more than 5) 
  • Occupation/recreation
  • Dehydration

6

What is the most important preventive advice for pts with exogenous erosion? 

Reduce frequecy of acidic foods and drinks, particularly outside meal times

7

How long does it take teeth to remineralise? 

2 hours

8

What is the fastest way to manage dentine hypersensitivity? 

Apply bond. Will last 6 months. might need to give LA to do it. 

9

What are the three main causes of loss of tooth surface

  • Attrition
  • Abrasion
  • Erosion

10

List 6 consequences of excess tooth surface loss

  • Loss of OVD
  • Loss of facial and dental aesthetics
  • Pseudo-prognathism
  • Loss of masticatory efficiency
  • Speech problems
  • Tooth sensitivity
  • Loss of self esteem

11

What is the rationale of txing tooth surface loss with composite/amalgam before fixed pros? 

  • Cost
  • Time
  • Avoid dentures
  • Protection of tooth structure
  • Easy to modify
  • Interim step before C&B

12

What sound indicates you are close to having anterior guidance? 

S

13

When you increase the OVD, the increase in facial height will be: 

Half of that

14

Dentate patients have considerable ability to adapt to increased OVD. 

True or false

True

15

What are the five principles of the occlusal scheme to follow: 

  • Bilateral posterior contact
  • Anterior guidance
  • Flat occlusal plane
  • Inter-arch stability (reduce differential and total wear)
  • Intra-arch stability (reduce tooth movement eg gaps)

16

Most people can function with 5-5 in each arch. What is the main limitation though? 

Smiling shows 6-6

17

What is the leading cause of teeth and cement breaking? 

Non-axial forces

18

How can you adjust teeth to improve axial loading? 

  • Increase fossa height
  • Reduce cusp height

19

What are the three main points to achieve when establishing occlusal contacts: 

  • Centric contacts on point or flats - not inclines
  • Never have a contact on a margin
  • Adjust teeth to reduce cusp angles

20

What is the second leading cause of teeth breaking after non-axial loading? 

Cavity depth

21

Two tools for increasing retention when increasing OVD: 

  • Boxes and grooves (amalgam)
  • Bonding

22

What are the two main reasons for loss of restorations within a short time frame

  • Not enough tooth structure to bond to
  • Haven't checked occlusion and left it high

23

What are the two main reasons composite fractures 

  • Load on tooth too heavy
  • Not enough thickness of material
