California Registered Dental Assistant (RDA) Written Practice Exam

Question: 1 / 400

What should be placed on the dental dam clamp before it is placed in the patient's mouth?

Anesthetic gel

Dental floss

Dental floss would be most correct to place on the dental dam clamp before it is placed in the patient's mouth because it helps create a tight seal around the tooth, preventing any fluids from leaking and ensuring a clean working area for the dentist. Anesthetic gel and dental wax would not provide the same level of security or protection. Additionally, using none of the above option would not serve the intended purpose of the dental dam clamp.
