1

Antiseptic

Substance for killing microorganisms on skin

2

Bioburden

Blood, saliva, and other fluids

3

Transfer surfaces

Surfaces that are not directly touched but are often touched by contaminated instruments

4

Splash, splatter, and droplet surfaces

Surfaces that do not contact the members of the dental team or the contaminated instruments or supplies

5

Precleaning

Removal of bioburden before disinfection

6

Residual activity

The action that continues long after initial application

7

Tuberculocidal agent

Capable of inactivating mycobacterium tuberculosis

8

Broad-spectrum

A disinfectant capable of killing a wide range of microbes

9

Iodophor

An EPA-registered intermediate-level hospital disinfectant

10

Synthetic phenol compound

An EPA-registered intermediate-level hospital disinfectant with broad-spectrum disinfection action

11

Glutaraldehyde

A high-level disinfectant or sterilant

12

Chlorine dioxide

Effective rapid-acting enviro surface disinfectant or chemical sterilant

13

Intermediate-level disinfectant

Destroys M. Tuberculosis, viruses, fungi, and vegetative bacteria and is used for disinfecting dental operators surfaces

14

Low-level disinfectant

Destroys certain viruses and fungi and can be used for general housecleaning purposes

15

Greener infection control

Minimizing enviro impact of infection control products and procedures

16

Why surfaces disinfected in dental rooms

Prevent patient to patient trans

17

What is used to prevent surface contamination

Sterilization and disinfectant

18

What is purpose of surface barrier

Prevent cross contamination

19

What agency requires use of surface disinfection

OSHA

20

Why surfaces precleaned

Remove bioburden

21

Where antiseptic used

On skin

22

What agency regulates disinfectants

EPA

23

What chemical solution recommended for heat-resistant items

Glutaraldehyde

24

Name for disinfectant that can leave reddish or yellowish stain

Iodophors

25

Disadvantage of synthetic phenols

Leaves residual film on surfaces

26

Common term for sodium hypochlorite

Bleach

27

Which disinfectant not effective if blood or saliva present

Alcohol

28

Common use of chlorine dioxide

Surfaces disinfectant and sterilant

29

Event-related packaging

It is assumed the contents of package will remain sterile indefinitely unless compromised

30

Sterilant

Agent capable of killing all microorganisms

31

Autoclave

Piece of equipment used for sterilizing by moist heat under pressure

32

Biologic indicators

Vials or strips (spore tests) contain harmless bacterial spores used to determine wether sterilizer working

33

Chemical vapor sterilizer

Used for sterilizing by hot formaldehyde vapors under pressure

34

Critical instrument

Used to penetrate soft tissue or bone

35

Semicritical instrument

Comes in contact with oral tissues but not penetrate soft tissue or bone

36

Noncritical instrument

Come in contact with intact skin only

37

Clean area

Area of sterilization are where everything clean and sterilized are stored

38

Contaminated area

Contaminated items brought for precleaning

39

Biologic monitor

Verifies sterilization

40

Single parameter indicator

Tapes, strips, and tabs change color when exposed to certain temps

41

Endospore

Resistant dormant structure formed inside some bacteria can withstand adverse conditions

42

Ultra sonic cleaner

Loosens and removes debris by sound waves

43

Multi-parameter indicator

Reacts to time, temp, and presence of steam

44

Basic rule of workflow pattern in an instrument processing area

Single-loop

45

If instruments not processed immediately what is done

Placed in holding solution

46

Methods of precleaning instruments

Hand scrubbing, ultra sonic cleaning, thermal washer and disinfector

47

method of precleaning instruments least desirable

Hand scrubbing

48

Kitchen dishwashers cannot be used to preclean instruments because they are

not FDA approved

49

Rusting of instruments prevented by

Lubrication

50

Instruments are packaged for sterilization to

Maintain sterility

51

Why aren't pins paper clips staples used

Cause holes in packaging
