4. Routes of
transmission
Inoculation
Direct contact of previously
damaged skin or mucous
membrane with a lesion or
injury due to contaminated
needle or debris from the oral
cavity
Inhalation
While using high
speed handpiece,
ultrasonic scalers

5. Why is infection control necessary in dentistry ?
Dental staff and patients may be exposed to a
wide variety of pathogenic microorganisms .

role in the infection control
Hepatitis B is a major
health hazard
Hepatitis B Vaccine is must

13. Personal protective equipment ( PPE )
Disposable

14. These PPE must be used whenever you :
Perform other clinical activities that require handling contaminated items e.g.
radiographs , impressions , dentures or contaminated equipment and surfaces .
Any contact with body fluids
Performing tasks that could produce splash or spatter .
vimal sikri pg no 145-149

15. HAND HYGIENE
vimal sikri pg no 145-149
Hand washing is the single most important
procedure for preventing the spread of
infection. So , you must wash your hands
each time before you put on gloves and
immediately after you remove gloves .

17. Before wearing personal protective equipment, the dentist and
staff need to remove chunky jewelry and wrist watch, and examine
their hands for cuts and bruises and hangnails

Water should follow from fingertips to the elbow & not
run back towards the area previously rinsed

19. After hand washing, the cuts and bruises should be medicated and
covered using a band aid/dressing to avoid coming in contact with patient
material

Gloves
Prevents contamination of hand and
control cross infection
Should be changed between patients
Don’t wash with detergents at any time

22. Remove gloves that are
torn, cut or punctured
vimal sikri pg no 145-149

23. Its an important barrier providing protection
from inhalation of aerosols, generated by
handpiece & air water syringes & also prevent
spatter from patients mouth
Don’t touch the mask with gloved hand
When wet should be changed

White Blue
vimal sikri pg no 145-149

26. White side contains
filter & if you have
flu, it should be
attached to your face
so that blue side faces
out so as to prevent the
germs from spreading
outward
vimal sikri pg no 145-149

27. vimal sikri pg no 145-149
Protecting clothing
Wear gowns, lab coats, or uniforms that cover
skin and personal clothing likely to become
soiled with blood, saliva, or infectious material
Change if visibly soiled
Remove all barriers before leaving the
work area

28. Its highly beneficial for dentists
Herpes virus infection of eye & infection
from hepatitis B are possible consequences
of viral contact with the eye by aerosol spray
Put an eyewear before gloving & remove it
with clean hand after gloves are removed

Eyewear

29. Operator’s hair has
to be kept away
from the treatment
field by means of
surgical cap.

30. All sharp instrument
should be disposed of
in designated puncture-
resistant containers

31. Clinical operating area
Special designated
plastic are used to
cover the chair and
unit Changes the bag
after each patient

32. Dental Unit Waterlines and Biofilm
It may be
contaminated
by biofilm.
Ramyya raghu pg no 172

33. Biofilm is the colonization &
proliferation of microorganisms on
surface bathed by fluids
Since the flow rate in dental unit is
very low, biofilms can readily form
here.
Ramyya raghu pg no 172

34. vimal sikri pg no 145-149

35. As a result the water emitted
from handpiece & Air water
spray may have high
concentrations of
microorganisms some of
which may be pathogenic
While using handpieces ,these
organisms can be introduced
into patient’s oral cavity from
where they have the potential
to initiate systemic infections
Ramyya raghu pg no 172

36. VARIOUS WAYS TO REDUCE THE FORMATION OF BIOFILMS
Periodic flushing of dental unit water lines
with sterile water or 1:10 dilution of 5.25%
sodium hypochlorite is recommended .
Minimum of 20-30 sec of flushing of
waterlines between patients is recommended
Ramyya raghu pg no 172

37. VARIOUS WAYS TO REDUCE THE FORMATION OF BIOFILMS
Filters & antiretraction valves may be installed
in the waterline as close as possible to the point
of use.
Ramyya raghu pg no 172

38. VARIOUS WAYS TO REDUCE THE FORMATION OF BIOFILMS
Use of sterile water delivery systems
can also reduce the risk of transferring
potentially infective organisms
Ramyya raghu pg no 172

transmission of dental infections ?

methods in dentistry .
