1. Intro to Fixed

Question 1

What are the three patient conditions that complicate treatment

Answer 1

• Medical issues
• Money
• Time (availability)

Question 2

T/F You can do a prophy before a comp oral if the patient’s hygiene is so poor your can’t properly evaluate the teeth

Answer 2

F- You can’t charge as a prophy it is a full mouth debridement (for comp eval and dx)

Question 3

(Amalgam/composite) marginal defects should be treated more aggressively and why

Answer 3

composite because amalgam seals with corrosion products

Question 4

The diameter of the explorer tip is proportional to what

Answer 4

the opening that can be detected

Question 5

The best way to evaluate the existance of an open margin is how

Answer 5

visual inspection + sharp explorer

Question 6

What are the advantages of supragingival margins

Answer 6

• Can be finished without soft tissue trauma
• Easily kept plaque free
• Impressions more easily made
• Easier restoration evaluation
• They are in enamel (subgingival=dentin)
• Exposure to fluoride and saliva

Question 7

When can a subgingival margin be justified

Answer 7

• Dental caries, cervical erosion or restorations extend subgingivally and crown lengthening is not indicated
• Proximal contact extends to the gingival crest
• Additional retention/resistance needed
• Hide a MCC margin (high lip line)
• Root sensitivity can’t be controlled by more conservative means
• Modification of axial contour(i.e provide undercut for retention of RPD clasp)

Question 8

Why do subgingival margins need to be more precise

Answer 8

more susceptible to inflammation and recession

Question 9

If perio surgery is needed, what should happen to the sulcular space?

Answer 9

Should have a postsurgical depth of 2 mm should NOT be eliminated completely

Question 10

How long does the gingival crest take to stabilize after perio surgery

Answer 10

20 weeks

Question 11

Extension of margins with _mm of the alveolar crest leads to resorption

Answer 11

1.5 mm

Question 12

Margins should follow the contour of the gingiva _ on the middle and _ interpreximally

Answer 12

apical… incisal

Question 13

Which has a greater risk of developing perio disease (over/undercountour) horizontal discrepancy

Answer 13

overcontoured

Question 14

(Vertical/horizontal) crown margin discrepancy predisposes to caries

Answer 14

vertical

Question 15

How do you evaluate an FDP for loose retainers

Answer 15

• Pull up on the connector with the explorer
• Push the retainer down with your finger
• Look for bubbling of saliva at the margin

Question 16

What is the definition of a problem

Answer 16

significant finding that has a treatment need which doesn’t fit the classic definition of a diagnosis

Question 17

What does a clinical finding become a problem

Answer 17

• A disease or condition with potential for disease
• Condition of dysfunction
• Esthetic issue with patient
• Condition that can’t be fully determined by simple clinical inspection
• Condition that complicates treatment

Question 18

For any treatment involving indirect restorations (fixed or removable) you must have what before tx.

Answer 18

mounted dx casts

Question 19

How should you address an urgent need for a patient coming in with a comp oral appointment

Answer 19

• Take vitals
• Update med Hx
• Stop the comp oral and discuss the urgent need with a faculty

Question 20

Give examples of dysfuntion

Answer 20

altered speech and mastication
