Which lubricant is applied to the rubber dam before placement to help it pass through tight interproximal contacts?
Answer: Water-based lubricant or shaving cream
Water-based lubricants (such as shaving cream or a commercial dam lubricant) reduce friction so the dam slides easily through contacts without tearing.
A floss ligature is used in rubber dam placement to:
Answer: Secure the dam at the anterior tooth and guide it through interproximal contacts
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.
What is the primary purpose of the rubber dam napkin placed between the dam and the patient's face?
Answer: To provide patient comfort by absorbing moisture and cushioning the skin
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.
A winged rubber dam clamp differs from a wingless clamp in that it:
Answer: Has lateral projections that hold the rubber dam during simultaneous placement of the clamp and dam
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.
If the rubber dam tears during a procedure, the EFDA should:
Answer: Remove and account for the torn piece, then replace the dam if necessary
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.
The 212 'butterfly' rubber dam clamp is specifically designed for use on:
Answer: Partially erupted or severely broken-down teeth with minimal clinical crown
The 212 clamp has an inverted bow design that allows it to engage tooth structure at or slightly below the gingival margin, making it useful for partially erupted or broken-down teeth.
Before removing the rubber dam at the end of the procedure, the EFDA should:
Answer: Cut all interdental septa of the dam with scissors before pulling it free
Cutting the interdental septa of the dam with scissors prevents the snapping of dam material against delicate gingival tissue and makes removal safe and comfortable.
