3. INTRODUCTION
Why do we need to know about infection
control?
•A study has found that 67% of materials sent
from dental office to laboratories were
contaminated with bacteria of varying degree of
pathogencity.`
5. Occupational Risks
•Infected saliva or
Direct contact blood
• From microbial
Airborne laden aerosols
infection
• During lab
spatter procedures
•When using knives and
other sharp items
6. CHAIN OF INFECTION

10. Infection control precautions
• Prevention of cross contamination should always
be a prime consideration in the dental lab.
•Appropiate personal protective
equipment
•Frequent hand hygiene
•Organization of dental lab into
separate receiving , production &
shipping areas.
11. BARRIER SYSTEMS
Hand washing Personal Protective
equipments
Plain or
antimicrobial Gloves
soap
Or an alcohol Mask & protective
based hand eye wear
rub
Chin length face
shield
Labcoat
12. Disinfection of impressions
IMPRESSION Iodophors and sodium
COMPOUND hypochlorite
REVERSIBLE Iodophors and sodium
HYDROCOLLOID hypochlorite
IRREVERSIBLE Iodophors and sodium
HYDROCOLLOID hypochlorite
POLYETHER Iodophors and sodium

ZOE IMPRESSION Glutaraldehydes, iodophors
PASTE
POLYSULFIDE Glutaraldehydes, iodophors
SILICONE Glutaraldehydes, iodophors
14. METHODS OF DISINFECTION
Methods of
disinfection
Spraying Immersion

16. ORALLY SOILED PROSTHESIS
Scrub with brush and antimicrobial
soap.
Place in plastic bag in ultrasonic
cleaning solution.
Removed Rinsed Dried
Accomplished required work.
17. DENTAL PROSTHESIS
Do not exceed the
recommended contact
time to minimize
corrosion.
Do not store in
disinfection before
insertion.
Store in diluted
mouthwash until
insertion.
18. DISINFECTION OF CASTS
Most difficult to disinfect
without causing damage.
In such cases, can be sprayed
with an iodophor or chlorine
product
Rinsed, handled in aseptic
manner
Transfer to the production
area.
Dry properly, if shipping.
19. LAB EQUIPMENTS
Polishing lathe requires special
attention.
Pumice has been shown to pose
a potential contamination risk
Via aerosol or direct contact
This act as a barrier in the path
of cross contamination.
20. CDC DENTAL GUIDELINES
Objectives - protect patients, practitioners , & staff.
All blood and saliva is infectious.
Reviews scientific information & makes recommendations to
protect the health of the population.
Tracks disease trends & investigates disease outbreaks
21. RESPONSIBILITY

Editor's Notes
Strive to make dental lab as safe as possibleMinimize potential for disease transmission viaImmunizationsBarrier techniquesAseptic techniquesIC complianceAdhere to Standard Precautions (SP)Establish written IC policyThe goal is to ensure compliance with universal barriers and other methods to minimize infection risks
Microrganisms capable of causing disease are present in human blood. Contact with blood or saliva mixed with blood may transmit pathogenic microorganisms.above these all can transmit pathogenic microrganisms from dental office to dental lab.
Routine Procedures.Through medical history Asymptomatic carriers Acceptance of patient It is unethical to refuse dental care to those patient with a potentially infections disease on the grounds that it could expose the dental clinician to personal risk.
Sir William Osler once remarked that Soap and water and common sense are the best disinfectants. Use of commonly available antiseptic hand wash like chlorhexidine is generally enough
