Dental infection control program
The process of preventing the access of micro-organisms
Washer, sterilizer, dishwasher, or other mechanical washing device.
The number of micro-organisms contaminating an object. AKA bioload or microbial load.
An unprocessed biological monitor from the same lot as the test monitor. When cultured, serves as a control by verifying the viability of the unexposed organisms.
A bacterial endospore test designed to assess whether sterilization has actually occurred. aka as a biological indicator or biological spore test.
Pathogenic micro-organisms that are present in human blood and capable of causing disease in humans.
A diagnostic test of a prevacuum sterilizer's ability to remove air from the chamber and prevent air reentrant. This is not a sterility assurance test.
The destruction or inhibition of most viruses and bacteria while in their active growth phase. The process does not necessarily kill all spores nor can it be verified by a monitor.
Chemical dyes used to determine whether the conditions required for sterilization are met. AkA as chemical monitor, dosage indicator, or process indicator.
The presence of reasonably expected presence of blood or other potentially infectious material on an item or surface.
Laundry that has been visibly soiled with blood or other potentially infectious materials or may contain contaminated sharps.
The propagation and growth of micro-organisms or living tissue cells in or nutrient medium.
Dental items are classified as critical, semicritical, or noncritical based on the pathways through which cross contamination may occur and the location and technique of the instrument use.
Dental Item classification.
Instruments and materials that penetrate the skin, mucous membranes, or bone. These items must be sterile before use. Examples include: surgical instruments, periodontal knives, and suture needles.
Instruments, equipment, or materials, that frequently contact mucous membrane but cannot be sterilized due to their design or inability to withstand heat. At minimum, these items require high-level disinfection. Examples include: radiographic positioning devices and plastic impression trays.
Instruments , equipment, or materials, that do not normally penetrate or contact mucous membranes but which are exposed to splatter, spray, or splashing of blood, or are touched by contaminated hands. These items require intermediate level disinfection. Examples include the dental unit and chair.
A specific eye, mouth, or other mucous membrane, nonintact skin, or percutaneous exposure to blood or other potentially infectious materials.
The total continuous elapsed time during which the sterilizers is operating at preselected sterilizing parameters, such as temperature and pressure.
Equipment or methods which isolate or remove bloodborne pathogens from the workplace. For example: Use of the rubber dam, use of the high volume evacuator during production of splash, splatter, and aerosols, adequate ventilation and air circulation, puncture proof sharps containers, closing the lid of ultrasonic cleaners during operation, use of cassettes to minimize handling of instruments during transport and sterilizing process.
Organisms capable of producing disease in appropriate hosts.
Termed "Regulated waste" defined as liquid or semi-liquid blood or other potentially infectious material (opim) contaminated items that would release blood or opim in liquid or semi-liquid state if compressed; items caked w/ dried blood or opim are capable of releasing the those materials during handling; contaminated sharps; and pathological and microbiological wastes containing blood or opim. Ref A includes saliva in dental procedures, any body fluid that is visibly contaminated w/ blood, and all body fluids in situations where it is difficult or impossible to differentiate between body fluids.
