  1. Instrument Decontamination & the Miele

  2. Dangerous little critters • Blood-borne pathogens • Other Potentially Infectious Materials (OPIM) • Creutzfeldt-Jakob disease

  3. Ewwww…there they are

  4. Well, that’s better

  5. IT’S THE LAW! • Section 1005. Minimum Standards for Infection Control: • All licensees shall comply with and enforce the following minimum precautions to minimize the transmission of pathogens in health care settings: • Standard precautions shall be practiced in the care of all patients. • A written protocol shall be developed by the licensee for proper instrument processing, operatory cleanliness, and management of injuries. • A copy of this regulation shall be conspicuously posted in each dental office. • Heat stable critical and semi-critical instruments shall be cleaned and sterilized before use by using steam under pressure (autoclaving), dry heat, or chemical vapor. FDA cleared chemical sterilants/disinfectants shall be used for sterilization of heat-sensitive critical items and for high-level disinfection of heat-sensitive semi-critical items.

  6. We don’t want no scrubs…or do we? • Presoak solution • Hand scrub • Ultrasonic • Washer (Miele) • Presoak & ultrasonic • Scrub & ultrasonic • Presoak & washer • Presoak, scrub & washer

  7. “A quantitative assessment of residual protein levels on dental instruments reprocessed by manual, ultrasonic, and automated cleaning methods.” 3 methods • Hand scrub • Hand scrub + ultrasonic • Washer 6 instruments • sickle scalers • extraction forceps • diamond burs • steel burs • matrix bands • matrix band holders Vassey, M, Budge, C, Poolman, T, et al.

  8. And the results are in: • No single instrument prevailed • No single method prevailed • 72% instruments had residual protein

  9. And the winner is… • Presoak solution • Hand scrub • Ultrasonic • Washer!!! • Presoak & ultrasonic • Scrub & ultrasonic • Presoak & washer • Presoak, scrub & washer

  10. “Decontaminating dental instruments: testing the effectiveness of selected methods” Procedures: • Dishwasher w/ water • Ultrasonic w/ water & rinsed • Presoak w/ 1oz cleanser & rinsed • Presoak w/ 4oz cleanser • Presoak w/ 4oz cleanser, an ultrasonic w/ detergent & rinse • Presoak w/ 4oz of cleanser, rinsed& dishwasher • Presoak w/ 4oz of cleanser & ultrasonic w/ 4oz of cleanser Sanchez E, Macdonald G.
