|
|
Definition

Dental Item Classification |
Dental items are classified as critical, semicritical, or noncritical based on the pathways through which cross contamination may occur and the location and technique of instrument use.
|
|
|
Definition
Critical Item |
Instruments and materials that penetrate the skin, mucus membranes, or bone. These items must be sterile before use
|
|
|
Definition
Semicritical |
Instruments, equipment, and materials that frequently contact mucous membrane but cannot be sterilized due to their design or inability to withstand heat. At minimum, items require high-level disinfection
|
|
|
Definition
Noncritical |
Instruments, equipment, and materials that do not normally penetrate or contact mucous membranes but which are exposed to splatter, spray, or splashing of blood, or touched by contaminated hands. Items require intermediate-level disinfecton
|
|
|
Definition
Engineering Controls |
Equipment or methods which isolate or remove bloodborne pathogens from the workspace
|

Definition
Sterilizer (gravity displacement type) |
A type of sterilizer in which incoming steam displaces the residual air through a port or drain usually in or near the bottom of the sterilizer chamber. 30 minutes at 121-123C(250-254F) and 15 to 17 pounds per square inch or 15 minutes at 132-135C(270-274F) and 30 to 32 psi
|
|
|
Definition
Sterilizer (prevacuum type) |
A type of sterilizer which relies on one or more pressure and vacuum exursions at the beginning or end of the cycle.Requires shorter cycle times at 132-135C
|
|
|
Definition
Work Practice Controls |
Controls that reduce the likelihood of exposure by altering the way one performs a task such as having patients brush their teeth, safe technique of recapping needles
|
|
|
Who appoints the Infectious Control Officer?
|
Co and OIC
|
|
|
The ICO must ensure that infection control functions are addressed at least ________
|
quarterly
|
|
|
To identify total resource s required to meet the guidelines of this directive and those of OSHA and the EPA, commands must use the ________
|
The planning, Programming, and Budeting System (PPBS)
|
|
|
Review and revise all infection control policies and procedures at least _______
|
Annually
|
|
|
What is the most preferable sterilization?
|
Heat sterilization
|
|
|
DTFs must have a central sterilization are because ________
|
Activity is safer, provides more efficient use of materials and personnel, and standardizes execution and monitoring procedures.
|
|
|
What are important considerations when planning a functional processing area?
|
The height and overall dimensions of the work surface, plus a clear surrounding area
|
|
|
When receiving and cleaning during sterilization, physical separation from the remainder of the sterilization area is ideal. If physical separation is not obtainable, __________ and _________ are critical
|
proper outfitting and equipment selection
|
|
|
What are the determinants of the space requirements for sterilization areas?
|
Size of and sufficient access for loading, unloading, and servicing the sterilizer.
|
|
|
True or False. Rinse and scrub contaminated instruments or materials in the patient treatment areas before taking it to the receiving section of the sterilization area.
|
False. Following the completion of a patient's treatment, take it directly to the receiving section of the sterilization area. Do not rinse, scrub, or unnecessarily handle contaminated instruments in the DTRs.
|
|
|
What kind of gloves should you wear while handling all potentially contaminated items?
|
Wear heavy, puncture proof gloves.
|
|
|
All contaminated, reusable items must be decontaminated by immersion in an EPA-registered disinfectant unless_________
|
Items are cleaned in an ultrasonic cleaner with an EPA-registered disinfectant which is also approved as an ultrasonic cleaner
|
|
|
The safest and provides an effective cleaning process.
|
Automated Washer Processor
|
|
|
Ultrasonic Cleaning
|
Safer and more effective than manual scrubbing. Always use baskets in the ultrasonic unit to reduce instrument handling and improve cleaning efficiency.
|
|
|
Manual Scrubbing
|
Time consuming and presents increased potential for contamination injury, but effective for cleaning instruments
|
|
|
