Infection control procedures

  2. 2. Elements in infection control protocol • patient evaluation • personal protection • instrument-cleaning, sterilization and storage • use of disposables • disinfection • laboratory asepsis • disposal of waste
  3. 3. Patient evaluation• Complete medical history should be taken prior to any treatment. • Update the medical history if any prior to each visit. –Identify the infectious diseases.
  4. 4. Personal protection • personal hygiene • clinic clothing • barrier protection (gloves, eye shield, face masks, rubber dam isolation) • immunization procedures.
  5. 5. Personal hygiene Nails • Nails should be cut short and be clean • Nail varnish should be intact, i.e. no chips or flakes. • Artificial nails are not permitted • Artificial nails can be a
  6. 6. Jewellery • No rings, bracelets or wristwatches should be worn during work. • It is not possible to wash hands and/or lower arms if these are covered in jewellery Eating, drinking and smoking
  7. 7. Clothing • During the treatment of patients and the handling of used instruments clothing with short sleeves should be worn in order to make good hand hygiene possible. • This clothing should be changed daily and in the case of visible contamination immediately. • During treatment clothing should not
  8. 8. Immunisation • All dentists and all the practice employees should be vaccinated against hepatitis B • because of the risk of exposure to blood and the possible risks it causes.
  9. 9. • A dedicated clean sink should be provided in the clinic for hand-washing, and the taps should be operated by elbow or foot controls or sensors (no-touch technique). • Thoroughly wash the hands before and after treating each patient using a proprietary antimicrobial handwash (e.g. chlorhexidine gluconate) before putting on gloves. • Hands should also be washed before leaving the surgery for any purpose, and upon return.
  10. 10. • Any obvious cuts or abrasions must be covered with adhesive waterproof dressings. • Liquid (not bar) soap should be used for routine handwashing, and antimicrobial liquids for hand-washing prior to surgical procedures. • Hands should be dried thoroughly using disposable paper towels, and gloves should be worn as the last step before treatment commences. • Moisturizing cream should be used as a
  11. 11. Barrier protection • gloves • eye shields • face masks • rubber dam isolation
  12. 12. Gloves • All dentists and close support personnel should routinely wear disposable latex or vinyl gloves. • to establish standards of hygiene in order to safeguard dental personnel and
  13. 13. • Gloves should be checked for visible defects immediately after wearing them, and immediately changed when breaches occur • never wash and reuse gloves. • allergic reactions to gloves may develop in staff or patients. • Skin creams, a spray-on
  14. 14. • clean, high-quality, protective latex gloves should be used whenever examining a patient's mouth or providing routine dental treatment when no blood-letting procedures are undertaken • sterile gloves should be used for surgical procedures
  15. 15. • heavy-duty utility gloves should be used for cleaning instruments or surfaces or handling chemicals.
  16. 16. Eye shields. • should be worn by dentists and close support personnel • to protect the conjunctivae from spatter and debris generated by high-speed handpieces, scaling (manual or ultrasonic), and polishing and cleaning of instruments.
  17. 17. Face masks. • clean mask should be worn for each patient. • particularly during high-speed instrumentation, as it prevents inhalation of contaminated aerosols
  18. 18. • The filtration efficacy of such aerosols depends upon: the material used for mask manufacture (paper masks are inferior to glass fibre and polypropylene types) length of time the mask is worn the useful life of a mask is about 30- 60 min, particularly if the ! mask is wet.
  19. 19. • Always ensure that masks are well adapted so that the nose and mouth are completely covered. • Masks with metal inserts are preferable as they can be tailored to fit the individual's profile. • Masks should not be touched
  20. 20. Rubber dam isolation • As far as possible rubber dam should be used in operative procedures Use of rubber dam during operative procedures: • provides a clear visual field as the tissues are retracted
  21. 21. • reduces aerosol formation, as saliva pooling does not occur on the rubber dam surface • minimizes the retraction of contaminated oral fluids into the dental unit water systems as the rubber dam prevents pooling of oral fluids and the possibility of suck-back into the water lines.
