-
bacteria or virus (pathogen).
-
the habitat in which the agent normally lives, grows, and multiplies. These include humans, animals, and the environment.
-
refers to the manner in which pathogen exits reservoir (saliva, feces, air droplets).
-
refers to the manner in which a pathogen enters a susceptible host (oral, blood, skin).
-
a host one whose biologic defense mechanisms are weakened in some way.
-
occurs when there is direct contact with infected blood, saliva, or other body fluids.
-
occurs when the dental healthcare professional comes in contact with a contaminated surface without the protection of personal protective equipment (PPE).
-
the process of eliminating or reducing harmful microorganisms from objects and surfaces.

-
used to penetrate soft tissue or bone, or enter into or contact the bloodstream or other normally sterile tissue. They should be sterilized after each use. These include forceps, scalpels, bone chisels, scalers and surgical burs.
-
do not penetrate soft tissues or bone but contact mucous membranes or non-intact skin, such as mirrors, reusable impression trays and amalgam condensers. These devices also should be sterilized after each use. In some cases, however, sterilization is not feasible and, therefore, high-level disinfection is appropriate.
-
come into contact only with intact skin such as external components of x-ray heads, blood pressure cuffs and pulse oximeters. Such devices have a relatively low risk of transmitting infection; and, therefore, may be reprocessed between patients by intermediate-level or low-level disinfection.
