DANB DANB Hand Hygiene & Surface Disinfection 2

Question 1

What is the two-step process for cleaning and disinfecting dental surface barriers when they are not used?

Accepted Answer

Clean with detergent, then disinfect with EPA-registered product

Answer

Surfaces without barriers must first be cleaned to remove debris, then disinfected with an EPA-registered hospital-grade product to kill remaining pathogens.

Question 2

Surface barriers (plastic wrap/covers) used in dentistry should be changed:

Accepted Answer

Between each patient

Answer

Surface barriers must be changed between each patient because they become contaminated during procedures and can transmit pathogens if left in place.

Question 3

Which alcohol concentration is most effective as a hand antiseptic?

Accepted Answer

60–95%

Answer

Alcohol concentrations of 60–95% are most effective at denaturing proteins and killing a broad spectrum of microorganisms on hands.

Question 4

When should surgical hand antisepsis be performed in a dental setting?

Accepted Answer

Before surgical procedures only

Answer

Surgical hand antisepsis is required before surgical procedures to reduce the resident microbial count on hands significantly more than routine handwashing.

Question 5

What product should NOT be used for hand hygiene in a dental office?

Accepted Answer

Alcohol-based hand rub

Answer

While alcohol-based hand rubs are acceptable for routine hygiene when hands are not visibly soiled, they should not replace soap and water when hands are visibly dirty or contaminated with blood.
