emergency preparedness
100
Penetrate mucous membranes or contact bone, the bloodstream, or other normally sterile tissues (of the mouth) Heat sterilize between uses or use sterile single-use, disposable devices Examples include surgical instruments, scalpel blades, periodontal scalers, and surgical dental burs
What is Critical Instruments
100
May become contaminated Not directly involved in infectious disease transmission Do not require as stringent decontamination procedures
What is Environmental Surfaces
100
Previously suctioned fluids might be retracted into the patient’s mouth when a seal is created Do not advise patients to close their lips tightly around the tip
What is Saliva Ejectors
100
Spread by droplet nuclei Immune system usually prevents spread Bacteria can remain alive in the lungs for many years (latent TB infection)
What is tuberculosis

Contact mucous membranes but do not penetrate soft tissue Heat sterilize or high-level disinfect Examples: Dental mouth mirrors, amalgam condensers, and dental handpieces
What is Semi-critical Instruments
200
sinks walls and floors
What is Housekeeping Surfaces
200
Wear gloves and other appropriate personal protective equipment as necessary Heat sterilize heat-tolerant accessories Transport and handle so that they will not become contaminated Avoid contamination of developing equipment
What is Dental Radiology
200
Assess patients for history Defer elective dental treatment If patient must be treated: DHCP should wear face mask Separate patient from others/mask/tissue Refer to facility with proper infection control precautions
