Clean? Disinfect? Sterilize? What does it all mean??

1. Clean? Disinfect? Sterilize?What does it all mean?? DA 116 Infection Control

2. Instruments, supplies, equipment, surfaces After each patient treatment procedure is completed

3. Clean? (“pre-clean”) • _________________________________ • Reduce the number of microbes and remove bioburden • Prevent debris from harboring microorganisms during sterilization process **if a surface is not CLEAN it cannot be disinfected** • Remove all disposables and contaminated items from operatory first • Use soap and water OR an EPA-registered product that cleans and disinfects

4. __________________ the operatory • _________________________

5. Pre-Cleaning Instruments preferred method: mechanical cleaning ______________________ ______________________

6. _____________? • _______________________________ • NOTthe same as sterilization • Kills most disease-causing microorganisms, but not spores • Non-pathogenic microorganisms may remain on an object after disinfection • Use an EPA-registered hospital disinfectant with tuberculocidal, HIV, and HBV claims • Note: Hydrogen Peroxide is NOT an acceptable disinfectant

8. Levels of Disinfection: • ____________________: (actually cleaning) • Least effective. Does not kill spores or Tuberculosis • _____________________ level disinfection: • Kills TB, which is the most difficult to kill as spores • If you use a process that kills TB spores, you will also be able to kill other organisms that are easier to kill (HBV and HIV) • __________________________disinfection: • Kills some, but not all bacterial spores, including TB as well as other bacteria, fungi and viruses • Almost as effective as true sterilization but not as thorough

9. Disinfectant Comparisonsnote: hydrogen peroxide and rubbing alcohol are NOT OSHA approved disinfectant

10. __________________ How to Use: For surface disinfection – use the 2 step method. • Clean by wiping surfaces thoroughly with disinfectant and paper towels or 4 x 4 gauze to remove all soils. • Disinfect by reapplying disinfectant, keeping surfaces wet for 10 minutes. Wipe off excess solution after contact time is completed. Place barriers.

11. ________________________ How to Use: For surface disinfection – use the 2 step method. • To clean, remove one or more wipe towelettes and wipe surfaces thoroughly to remove all soils. Discard used wipe towelettes. • Remove one or more additional fresh wipe towelettes. Reapply disinfectant to previously cleaned surfaces for a 10 minute contact time.

12. Additional Disinfecting Concerns: _____________________ ____________________ • Film holders and positioners for digital radiographs should be heat sterilized between patients, UNLESS they are disposable items. • Sensors for digital radiographs cannot be sterilized and should be covered with a new barrier sleeve for each patient. • All items used in the mouth should be cleaned and soaked in a high level disinfectant before sending to the laboratory for processing.

13. __________? • ______________________________________________________________ • destroys all living microorganisms, including bacterial spores and viruses. Kills good and bad microorganisms, all life • After proper sterilization, no microorganisms will be alive • Heat or Liquid Chemical

14. Steam under pressure _____________________ ______________________

18. Liquid Sterilant(cold sterilant or high-level disinfectant) • ________________ product

19. Sterilization Monitoring • Biological monitoring with spore tests: Liquid Disinfectant Monitoring: color monitor dip stick (not a spore test) • Process indicators
