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 Minimum Standards for Infection Control: c) All licensees shall comply with and enforce the following minimum precautions to minimize the transmission of pathogens in health care settings : 1) Standard precautions shall be practiced in the care of all patients. 2) A written protocol shall be developed by the licensee for proper instrument processing, operatory cleanliness, and management of injuries. 3) A copy of this regulation shall be conspicuously posted in each dental office. 9) 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.
