What is a major advantage of using a disposable item versus its reusable counterpart?

A)Using disposables is always less expensive.
B)Disposables can be used on two to three patients, saving cleaning and sterilization time and labor.
C)Disposables always have a more efficient operation.
D)Disposables are the best way to prevent patient-to-patient spread of contamination.

C)Touching as few surfaces as possible
D)Using disposable high-volume evacuator tips

Question 13

Which of the following will minimize the spread of patient materials to the dental team?

C)Using a reusable rather that a disposable high-volume evacuator tip
D)Using an overglove when leaving chairside

Question 14

Which of the following procedures would give additional protection (above that from wearing appropriate personal protective barriers) when changing or cleaning the vacuum line trap?
