Q: When is a package considered to be contaminated? 

A. When it is dropped on the floor
B. When it is punctured
C. When it is wet
D. All of the above

Before opening a dental instrument package, examine it carefully chair side. Packages that are dropped on the floor, punctured, torn or wet are considered contaminated. In those events, repackage and re-sterilize the instruments, let the package dry completely, and carefully transport the sterilized package chair side.


   Answer: (D). All of the above


Now let’s review the most important key points in sterilization for the Dental Assisting National Board® Examination:

Use a closed transportation box to move the instruments to the processing area.

Wear puncture- and chemical-resistant heavy-duty utility gloves for instrument cleaning and decontamination procedures.

Clean debris by hand washing or automated process (ultrasonic cleaner or automatic washer).

Wear puncture-resistant utility gloves when packaging instruments.

An internal chemical indicator should be placed in every package.

In addition, an external chemical indicator (e.g., chemical indicator tape) should be used when the internal indicator cannot be seen from outside the package.

Instrument packs should be allowed to dry inside the sterilizer chamber before they are removed.

Storage area should be enclosed and dry.

Instruments should be cooled before being stored.

      Write the date and sterilizer used on the packaging.

If you use SmarterDA Dental Assisting Boards Review, make sure to review this chapter on Infection Control. The good news is that there is not a ton of information to remember (compared to oral pathology or head and neck anatomy).
