Food and Drug Administration (FDA)

division of the US department of Health and Human Services, and regulates the manufacturing and labeling of medical devices and solutions.

Glutaraldehyde

chemical disinfectant that is used for high-level disinfection and sterilization.

Host

simple or complex organism that can be affected by an agent.

Indirect contact

individual contacts the microorganism through another means, such as contaminated instruments, supplies, or equipment.

Infection control

methods to eliminate or reduce the transmission of infectious microorganisms.

Inhalation

to breath in drugs.

Iodophor

intermediate-level disinfectant.

Latex allergies

people who are allergic to latex.

Material safety data sheet (MSDS)

information about labeling and hazardous waste in employee training.

Mode of transmission

process that bridges the gap between the portals of exit from the infectious agent to the portal of entry of the host.

Occupational exposure

any reasonably anticipated eye, mucosa, skin, parenteral, or any contact with blood or saliva that may result in employee injury.

Occupational Safety and Health Administration (OSHA)

regulates requirements that employers must protect their employees from exposure to blood and other potentially infectious materials (OPIM).

Organization for Safety and Asepsis Procedures (OSAP)

national organization that encompasses dental health care workers, distributors of dental equipment and materials, health care instructors, dentists, and others in the field of dentistry.

Other Potentially Infectious Materials (OPIM)

materials that may pose a threat in a dental workplace.

Overglove

gloves that are placed over latex gloves to prevent cross-contamination.

Parenteral

a cut, needlestick, puncture, or abrasion.

Pathogens

disease producing microorganism

Pericardial

heart fluid.

Peritoneal

abdominal fluid.

Personal Protective Equipment (PPE)

worn to protect from contact with bodily fluids, whether or not blood is visible.

Phenolics

chemical disinfectant for intermediate disinfection.

Pleural

lung fluid.

Portal of exit

the route by which an infectious agent leaves the reservoir to be transferred to a susceptible host.

Portal of entry

route by which an infectious agent enters the host.

Recommendations

guidelines that are not mandated.

Regulations

licensing boards which create authority to enforce compliance.

Reservoir

place when an agent can survive.

Sanitized

decontaminated, but not all microorganisms have been destroyed.

Spray-wipe-spray-wipe technique

spray and wipe a surface. Spray again and leave on surface for at least 10 minutes, then wipe down the surface again.

Standard precautions

universal precautions and body substance isolation techniques.

Sterilization indicators

ensures that sterilizing units are not over-packed.

Sterilization

all organisms are destroyed.

Susceptible host

one who lacks resistance to an agent.

Synovial

joint and tendon fluid.

Type 1 Allergic reaction

occurs within minutes of an allergen exposure.

Type IV Allergic reaction

exposure to chemicals that are added to latex, resulting in an allergic reaction.

Universal precautions

all patients are treated as though they are infectious.

Utility gloves

gloves used for disinfection and cleaning up infections.

Vectorborne transmission

occurs when an agent is transferred to a susceptible person host by animate means.

Vehicle transmission

occurs when the agent is transferred to a susceptible host by contaminant inanimate objects.

Emollient

Rubs soothing to the skin that help reduce drying of the skin

Thermal disinfector

Uses heat to kill most vegetative microorganisms

Alcohol-based hand antiseptic

Isopropanol, ethanol, n-propanol, or a combo of these products

Fomite

objects contaminated with infectious agents such as instruments or dressings.
