Q

What is the main goal of harm prevention?

A

1) Prevent excessive saliva and/or moisture pooling
2) Prevents fluids and/or small instruments from being swallowed or aspirated
3) Prevents soft tissues from being cut or damaged.

Q

What are the advantages of Rubber Dam?

A

1) Effective for long appoinments
2) Dry, clean operating field
3) Improved visibility and access
4) Maximizes patient safety
5) Enhances patient comfort
6) Maximizes operator safety and effieciency

17
Q

What are the disadvantages of Rubber Dam?

A

1) Time consumption
2) Patient Objection
3) Cannot be used for all patients

18
Q

What kind of special conditions can a Rubber Dam not be used?

A

1) Partial eruption (unable to hold a retainer)
2) Malpositioned teeth
3) 3rd molars
4) Patients with impaired nasal breathing
5) Lesion position/location

19
Q

What is the advantage of a thin rubber dam material?

A

Easy to apply and comfortable.

20
Q

What is the advantage of a heavy rubber dam material?

A

Improved resistance to tearing and improved retraction.

21
Q

What is the function of the retainer (clamps)?

A

To provide a stable anchor for the system at the most distal aspectb

22
Q

What are the components of a retainer?

A

1) 4 prongs
2) 2 holes
3) Jaw
4) Bow
5) Wings (not present all the time)

23
Q

What is the function of the frame?

A

To hold and stretch the RD material to improve visibility and help create a “space” for access.

24
Q

What does each number hole in the hole punch correspond to?

A 
#1: primary incisors
#2: smallest incisors
#3: maxillary central incisors, canines and premolars
#4: large premolars/small to normal molars
#5: large molars
#6: large molars and the tooth to be clamped
25
Q

When do you use lubricant with a rubber dam?

A

When there is difficult interproximal areas and to aid in patient comfort of the lips.

26
Q

Why is vasoline a poor choice of lubricant?

A

Prevents inversion, difficult to remove and it is not water soluble.

27
Q

What are the 5 steps of rubber dam usage?

A
  1. Determine the operarting field
  2. Prepare the RD
  3. Select the proper retainer
  4. Place the RD
  5. Remove the RD
28
Q

Where do you place the retainer for posterior teeth?

A

A minimum of 1 tooth distal to the tooth being restored & cross the midline with holes.

29
Q

Where do you place the retainer for anterior teeth?

A

From 1st bicuspid to 1st bicuspid.

30
Q

How many retainers should be used for anterior teeth?

A

One retainer MUST be used and two retainers MAY be used.

31
Q

If the rubber dam is powdered, which side does the powder side go?

A

Towards the face of the patient.

32
Q

What must you ALWAYS do with the retainer bridge?

A

Attach floss to it.

33
Q

Where do ligatures go?

A

On the tooth being restored AND on each adjacent tooth.
