INTRODUCTION
• A study has found that 67% of materials sent from dental office to laboratories were
contaminated with bacteria of varying degree of pathogencity.`
Why do we need to know about infection control?
Scope of this presentation
Dental care health personnel
Dental assitants
Dental technicians
Dental Students
Dental camps patients
Occupational Risks

• During lab procedures
• When using knives and other sharp items
• Infected saliva or blood

IMPRESSION TRAYS
• Prevention of cross contamination should always be a prime consideration in the dental lab.
Infection control precautions
• Appropiate personal protective equipment
• Frequent hand hygiene
• Organization of dental lab into separate receiving , production & shipping areas.
BARRIER SYSTEMS
Plain or antimicrobial soap
Or an alcohol based hand rub
Personal Protective equipments
Gloves
Mask & protective eye wear
Chin length face shield
Labcoat

METHODS OF DISINFECTION
DENTAL LAB PROCEDURES
INCOMING ITEMS
Rinse to remove blood & saliva
Disinfect Again rinse to remove
disinfectant
Add the annotate form
ORALLY SOILED PROSTHESIS
Scrub with brush and antimicrobial soap.
Place in plastic bag in ultrasonic cleaning solution.
Removed Rinsed Dried
Accomplished required work.
DENTAL PROSTHESISDo not exceed the
recommended contact time to minimize
corrosion.
Do not store in disinfection before
insertion.
Store in diluted mouthwash until
insertion.
DISINFECTION OF CASTSMost difficult to disinfect without causing damage.
Rinsed, handled in aseptic manner
Transfer to the production area.
Dry properly, if shipping.
LAB EQUIPMENTS
Polishing lathe requires specialattention.
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.
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
