Room
Dr Mohd Malik Afroz
Format
• Personal Protective Equipment
• Contamination of Dental Processing Solutions
• Surface Disinfection and Barriers
Specific Learning Objective
•
Improve effectiveness and impact of public
health interventions
Inform clinicians, public health practitioners,
and the public
• Based on a range of rationale, from
systematic reviews to expert opinions
•
Background
Why Is Infection Control Important
in Dentistry?
•
•
•
Both patients and dental health care personnel
(DHCP) can be exposed to pathogens
Contact with blood, oral and respiratory
secretions, and contaminated equipment occurs
Proper procedures can prevent transmission of
infections among patients and DHCP
Modes of Transmission
•
•
•
•
Direct contact with blood or body fluids
Indirect contact with a contaminated
instrument or surface
Contact of mucosa of the eyes, nose, or
mouth with droplets or spatter
Inhalation of airborne microorganisms

Standard Precautions
•
•
Apply to all patients
Integrate and expand Universal Precautions
to include organisms spread by blood and
also
– Body fluids, secretions, and excretions except
sweat, whether or not they contain blood
– Non-intact (broken) skin
– Mucous membranes
Elements of Standard Precautions
•
•
•
•
•
Handwashing
Use of gloves, masks, eye protection,
and gowns
Patient care equipment
Environmental surfaces
Injury prevention
Personal Protective Equipment
• Use of gloves
• Proper handling of contaminated materials
like the exposed x ray films
• It is not usually necessary to wear long gowns,
protective eye wear while exposing the
patients or developing films.
Handling of X ray Films
• The film holder must be sterilized for
each patient.
 Double gloved method for day light
loader.
• Once the x ray film is taken it should
be transferred in a disposable glass.
• The radiographer should use
disposable glove to handle the
exposed radiograph.
• The radiograph must be removed
from its cover in such a way that the
film holder clip fits into it.
• The radiographer
should use disposable
glove to handle the
exposed radiograph.
• The radiograph must be
removed from its cover
in such a way that the
film holder clip fits into
it.
• The gloves must be removed along with the
film packet and should be thrown separately
• The exposed film is individually dipped in the
processing solutions and then kept for drying
Contamination of Processing Solutions
• Cross contamination of the processing
solution due to mishandling of x ray films
• Contamination of solution while transporting
the x ray film from one solution to another
• Then the film is kept for the drying and given
to the patient in a clean cover with name,
type of exposure and the tooth of interest
mentioned on it for interpretation.
