Study Notes
Infection Control Terminology
- Antiseptic: A substance used to kill microorganisms on the skin.
- Bioburden: The presence of blood, saliva, and other body fluids on a surface.
- Broad-spectrum activity: The ability of a disinfectant to kill a wide range of microbes.
- Chlorine dioxide: A disinfectant used for environmental surfaces and as a sterilant.
- Clinical contact surface: Surfaces touched by contaminated hands, instruments, or spatter during dental treatment.
- Disinfectant: A chemical used to reduce the number of microorganisms on inanimate objects.
- Environmental surface: Surfaces that do not directly involve patient care but may become contaminated during treatment (e.g., countertops, floors).
- Fungicidal: A product that kills fungi.
- Glutaraldehyde: A high-level disinfectant registered by the Environmental Protection Agency (EPA).
- Greener infection control: Minimizing the environmental impact of infection control products and procedures.
- High-level disinfectant: A hospital disinfectant with tuberculocidal activity.
- Hospital disinfectant: A disinfectant that can kill Staphylococcus aureus, Salmonella choleraesuis, and Pseudomonas aeruginosa.
- Housekeeping surface: Surfaces that are not contaminated during dental treatment (e.g., floors, walls).
- Immersion disinfectant: A disinfectant used for soaking heat-sensitive instruments.
- Intermediate-level disinfectant: A liquid disinfectant with EPA registration as a hospital disinfectant with tuberculocidal activity. Used for disinfecting operatory surfaces.
- Iodophor: An EPA-registered, intermediate-level hospital disinfectant.
- Liquid sterilant: A chemical used to sterilize items damaged by heat sterilization.
- Low-level disinfectant: A disinfectant used for general housecleaning (e.g., walls, floors).
- Precleaning: The removal of bioburden before disinfection.
- Residual activity: The ability of a disinfectant to continue working long after initial application.
- Reuse life: The time period during which a disinfectant remains effective during use and reuse.
- Shelf life: The length of time a product can be stored before use.
- Single-use items: Items used only once and then disposed of (e.g., single-use gauze).
- Sodium hypochlorite (household bleach): A surface disinfectant.
- Splash, spatter, and droplet surface: Surfaces that do not directly contact the dental team or contaminated instruments or supplies.
- Sporicidal: Capable of killing bacterial spores.
- Sterilization: The process of killing all microorganisms.
- Surface barrier: A fluid-resistant material used to cover surfaces likely to become contaminated.
- Synthetic phenol: An EPA-registered intermediate-level hospital disinfectant with broad-spectrum disinfecting action.
- Touch surface: Surfaces directly touched and contaminated during a procedure.
- Transfer surface: Surfaces not directly touched but often contacted by contaminated instruments.
- Tuberculocidal: Capable of inactivating tuberculosis-causing microorganisms.
- Virucidal: Capable of killing some viruses.
