Q

4 Desirable characteristics of primary preparations

A

Conservative
Extended sufficiently to remove all caries
Prep design should provide adequate retention for resto. material
Pulpal floor should be of uniform depth and slightly rounded

16
Q

Dimensions of a typical amalgam class I

A

1.5 mm depth

1/3 intercuspal width

17
Q

3 considerations for class II preps

A

The buccal and lingual walls of the prep should converge toward the occlusal surface

The portions of the prep that extend into the buccal and lingual grooves and the marginal ridge area should be PARALLEL or slightly DIVERGE to preserve tooth strength

I deal width of isthmus is 1/3 intercuspal width

18
Q

What is the ideal width of the floor of the box

A

1 mm

19
Q

Axially, how should the proximal box be designed?

A

Slightly into dentin, so the axial wall is slightly undercut

20
Q

Should you bevel the gingival line angle?

A

No

21
Q

Which part of the box should be beveled?

A

Axio-pulpal line angle

22
Q

What should you do if you think your class II prep is encroaching on the pulp?

A

Use a base material, like glass ionomer

23
Q

What is essential for class II restorations

A

Matrix band

24
Q

What type of matrix band is made of soft material in order to readily adapt to contours

A

Tee Band

25
Q

What is another advantage of tee bands?

A

No intraoral apparatus is needed

26
Q

What restoration step is critical when using a Composite material

A

Isolation and moisture control

27
Q

What are the 7 Common errors for Class II Preps/Restorations

ON TEST FOR SURE

A
  1. Failure to extend occlusal outline into all susceptible pits and fissures
  2. Failure to follow the outline of the cusps
  3. Isthmus cut too wide
  4. Flair of proximal walls too great
  5. Angle formed by the axial, buccal, and lingual walls too great.
  6. Gingival contact with adjacent tooth not broken
  7. Axial wall not conforming to the proximal contours of the tooth and the mesial distal width of the gingival floor is too great
28
Q

What two burs are used for a class III restoration

A

No. 33.5 inverted cone OR a small round bur

29
Q

Describe the shape of a class III preparation

A

Triangular, with the base of the triangle at the gingival area

30
Q

How is retention created in the class III prep?

A

Via undercut by the shape of the bur

31
Q

Why is dentin bonding less effective in primary teeth?

A

Less mineralization of tissue

32
Q

When might a crown become indicated when working on a class III

A

If the incisal area becomes thin and you are looking at a class 4. Crowns are used instead of class IV’s

33
Q

Where are class III restorations not well retained

A

Maxillary anterior teeth

34
Q

Where are class III restorations rarely retained

A

Mandibular teeth

35
Q

When doing anterior restorations, what type of matrix is used

A

Mylar

36
Q

What is critical to check before finishing composite resin restorations

A

that the prep is completely dry and free of contaminates such as blood

37
Q

When evaluating a molar for a class V, when is a crown indicated?

A

If the caries extends beyond the line angles of the tooth into the interproximal areas
