Q

Periodontally compromised dentition is defined as

A

-relationship of the tooth with alveolar bone compared with the portion not withinthe alveolar bone

21
Q

Fulcrum of the abutment tooth is a class _ lever

A

I

22
Q

T/F Most roots are conical

A

t

23
Q

How can the CRR be improved

A

Prepping the abutment tooth (decreases the crown height –> decrease in C:R ratio)

24
Q

(T/F) Increased crown mobility is associtated with increased CRR and increased mobiliy is found in teeth with large CRR

A

1= T 2=F

25
Q

What are the four different prognostic factors when evaluating a tooth

A
  • Perio
  • Endo
  • Implant
  • Prosth
26
Q

The different aspects of perio prognostic factors are

A
  • Attachment loos
  • Probing depths
  • Furcation involvement
27
Q

The major prosth prognostic factor is

A

-Amount of coronal tooth structure remaining

28
Q

Endo prognostic factors say that survival rates in FDP abutments with RCT are (more/less) likely to survive

A

less

29
Q

As long as the planned restoration is a _ in an otherwise intact arch a questionable tooth might be accepted

A

single crown

30
Q

Most complications with pins are… second is

A 
1st= loose pin/inadequate penetration of the pin in the channel 
2nd= perforation or pulp/periodontium
31
Q

What is the best core build up material under conventionally cemented crowns

A

amalgam

32
Q

Main disadvantage of amalgam is what

A

hg content

33
Q

The liberation of metalic ions from amalgam is inhibitied by what

A

the crown cement

34
Q

Unless the patient suffers from _ the metalic ions from amalgam will not likely be an issue

A

lichen planus

35
Q

What is wet bonding

A

is it when the dentin is left slightly damp after etching and rinsing to encourage better primer penetration

36
Q

The crown margin should embrace - mm of sound tooth structure cervically

A

1-2 mm (extension of the margin like this= ferrule effect)

37
Q

Describe the risk of ceramic fracture with GI

A

Hydrophilic resin (swelling occurs)

38
Q

How can the seal of a RD be improved

A

OraSeal Putty
Stringent (decrease bleeding
Electrosurgery (reduce the gingival margin)

39
Q

An Apex locator will read what if a pin has perforated the periodontium

A

beyond the apex

40
Q

Which are easier to manage pulpal or periodontal perforations

A

pulpal

41
Q

(T/F) Ferrule lowers the impost of the post and core system, luting agents of endo treated teeth

A

t

42
Q

The need for endo after indirect restorations is higher in single crown or FDP

A

FDP

43
Q

Reduction of tooth stiffness in endo teeth largely due to

A

access

44
Q

What is the most common post and core failure

A

loosening of the post and tooth fracture

45
Q

Threaded posts are the most retentive followed by…

A

cemented and parallel sided

46
Q

What posts produce the least root stress? Most likely to cause root fracture?

A

cemented… threaded

47
Q

As the number of proximal contacts increases the survival rate of RCT with crowns (increases/decreases)

A

increases

48
Q

Parallel sided serrated posts (increased/decreased) RCT tooth longevity

A

increased
