Infection control in dental lab 1
- 1. INFECTION CONTROL IN DENTAL LAB PRESENTED BY: ANKIT PRABHAKAR GENESIS INSTITUE OF DENTAL SCIENCES AND RESEARCH,FEROZEPUR PUNJAB
- 2. CONTENTS 1 Introduction 2 Scope and objectives 3 Transmission of infection 4 Clinical and laboratory disinfection 5 CDC dental guidelines for sterilization of instruments
- 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.`
- 4. Scope of this presentation
- 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 Pathogen Reservoir Susceptible host Portal of entry Direct contact Indirect contact
- 7. GOALS/ ACTIONS Make dental Minimize IC compliance lab safe potential Immunization Barrier techniques Aseptic techniques
- 8. Transmission of infection IMPRESSION IMPRESSION ARTICULATOR TRAYS Transmission of infection CASTS OCCLUSAL RIMS DENTAL PROSTHESIS
- 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 hypochlorite ZOE IMPRESSION Glutaraldehydes, iodophors PASTE POLYSULFIDE Glutaraldehydes, iodophors SILICONE Glutaraldehydes, iodophors
- 14. METHODS OF DISINFECTION Methods of disinfection Spraying Immersion Same Uses less Exposure of all disinfectant can preferrable disinfectant surfaces be used again
- 15. DENTAL LAB PROCEDURES INCOMING OUTGOING ITEMS ITEMS Rinse to Clean and remove blood disinfect & saliva Rinse, dilute Disinfect with mouthwash Again rinse to Place in remove plastic bag disinfectant Add the Label the annotate form plastic bag
- 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 Responsibility Universal Standard Practical code precautions precautions Procedure kept Protect Blood as well cross infection exposure from as from body control blood fluids also.
- 22. GENERAL PREVENTION VACCINATION MEDICAL HISTORY 30 •In order to identify 25 pathological conditions, 20 15 10 •Drug induced conditions 5 0 •Malformations & HIV HBV HCV abnormalities Average Risk of Transmission after Percutaneous Exposure to Blood
- 23. SPECIFIC GUIDELINES These guidelines apply in the care of all patients. Disposal of wastes Cleaning and maintainance Personal hygiene
- 24. SUMMARY Adhering to Wearing Standard protective precautions personal equipments Aseptic techniques PREVENTION OF DISEASE TRANSMISSION

Notes de l'éditeur
- 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
