Infection Control for Dental Assisting
Terms in this set (54)
What are the main causes of disease?
What happens when germs multiply?
Germs become diseases
The chain of infection contains four links:
2.) Number of microogranisms
3.) Susceptible host
4.) Portal of Entry
What is the virluence of an organism?
It's strength or ability to cause disease
Number of Microorganisms
Describes the amount of pathogens present
What is a susceptible host?
Someone who has a compromised immune system
What is the portal of entry?
The way in thich an infection enters the body
What is an infectious disease?
A disease that is contagious an can be transmitted from host to host via the chain of infection.
This route of transmission occurs when there is direct contact with infected blood, saliva, or OPIMs
What does OPIM stand for?
Other Potentially Infectious Materials
This route of transmission occurs when the dental healthcare professional come in contact with a contaminated surface without the protection of PPE.
Personal Protective Equipment
This route of transmission occurs through methods of inhalation.
-Aerosol, Spray, or Spatter
This route of transmission only occurs from blood-to-blood contact with an infected individual.
Refers to germs within or from the dental setting being transmitted to other areas of the dental office or carried out of the dental setting.
Disease Transmission in the Dental Office:
-Patient to Patient
-Healthcare Worker to Patient
-Patient to Healthcare Worker
-Healthcare Worker to Community
What does OSHA stand for?
Occupational Safety and Health Administration
What does CDC stand for?
Centers for Disease Control and Prevention
OSHA's Blood-Borne Pathogens (BBP) Standard
Discusses how the dental office deals with, and its plan for, exposure to blood-borne pathogens.
Mandates that all patients be treated as if they have a deadly disease, regardless or their health history
An expansion of universal precautions.
- The infection control protocol for each patient will be the same, no matter what.
What are OSHA's categories of employees based on?
His/Her exposure risk to blood, saliva, or bodily fluids. (Category 1 is the highest risk category)
What vaccination does OSHA require that every dentist offer and pay for their employees?
Hepatitis B vaccination
Management of Sharps Waste:
Sharps must be disposed of in a biohazard, non-permeable, red plastic container.
What PPE is required for a dental assistant?
Proper PPE includes:
-Safety glasses/face sheild
PPE should be removed in the following manner:
2.) Wash hands
3.) Safety glasses
5.) Lab Coat
6.) Second hand washing
Classification of Waste:
1.) General Waste
2.) Contaminated Waste
3.) Hazardous Waste
4.) Infectious Waste
5.) Biohazardous Waste
The process of killing some microorganisms, but not all
Latex, vinyl, or nitrile materials that are most often worn by members of the dental team
Gloves used to break down a contaminated treatment room and to handle contaminated instruments. (Can be disinfected and/or sterilized in the autoclave)
Gloves used when an assistant must leave the treatment room, open a drawer during the procedure to retrieve a supply, or to make notes.
Gloves utilized during surgical procedures
Used to kill some of the microorganisms prior to sterilization (Two most popular: iodophors & gluteraldehydes)
The process that completely destroys microorganisms (including bacteria & spores) on instruments, equipment, and surfaces.
What are the 3 categories instruments are classified?
1.) Critical Instruments
2.) Semi-critical Instruments
3.) Non-critical Instruments
Instruments that contact of penetrate soft tissue or bone
Examples of critical instruments include:
Scalpels, burs, and scalers
Instruments that come in contact with the oral cavity but do not penetrate soft tissue or bone
Examples of semi-critical instruments include:
Amalgam carriers, and condensers
Instruments that pose the least risk of spreading infection because they do not come in contact with soft tissue, membranes, or broken skin
Examples of non-critical instruments include:
X-ray unit position indicator device, or X-ray film holder
What are the seven steps of instrument processing?
7.) Quality Assurance
What are four of the leading methods of sterilization?
3.) Flash Sterilization
4.) Cold Sterilization
How does an autoclave sterilize instruments?
By converting water to steam and pressurizing it (steam under pressure).
How long is the average cycle of an autoclave?
30 minutes: 20 minutes at 250 degrees, and 10 minutes venting time.
Under what conditions are spores killed?
High heat and pressure (Autoclaving)
Converts chemical vapor into steam and pressurizes it (unpleasant odor)
Utilized in an office when a particular instrument is needed right away (Average cycle = 3 minutes)
Three forms of Sterilization Monitoring:
Involves checking the readings on the indicators to denote that a certain temperature level was reached
Using heat-sensitive chemicals that change color under certain conditions.
Involves spore testing to establish whether the sterilization process was successful.
How often does OSHA mandate that you test every sterilization device utilized in the office?
What are the only two ways to properly sterilize hand pieces?
Steam or chemical vapor sterilizers (hand pieces should be packaged before being sterilized)
