EFDA Rubber Dam Placement and Removal 2

Question 1

Which lubricant is applied to the rubber dam before placement to help it pass through tight interproximal contacts?

Accepted Answer

Water-based lubricant or shaving cream

Answer

Water-based lubricants (such as shaving cream or a commercial dam lubricant) reduce friction so the dam slides easily through contacts without tearing.

Question 2

A floss ligature is used in rubber dam placement to:

Accepted Answer

Secure the dam at the anterior tooth and guide it through interproximal contacts

Answer

Dental floss serves as a ligature to hold the dam at the most anterior isolated tooth and to work the dam through tight contacts by flossing it into place.

Question 3

What is the primary purpose of the rubber dam napkin placed between the dam and the patient's face?

Accepted Answer

To provide patient comfort by absorbing moisture and cushioning the skin

Answer

The rubber dam napkin (cloth or paper) is positioned between the dam and the patient's face to absorb moisture, prevent skin irritation, and increase patient comfort.

Question 4

A winged rubber dam clamp differs from a wingless clamp in that it:

Accepted Answer

Has lateral projections that hold the rubber dam during simultaneous placement of the clamp and dam

Answer

Winged clamps have lateral wings that hold the rubber dam material, allowing the clamp and dam to be placed together in one step rather than placing the clamp first.

Question 5

If the rubber dam tears during a procedure, the EFDA should:

Accepted Answer

Remove and account for the torn piece, then replace the dam if necessary

Answer

A torn dam piece must be located, removed, and accounted for to eliminate any aspiration or ingestion risk before proceeding; the dam should then be replaced.
