HIV/AIDS Precautions - Dental

What precautions should I take when employed in the dental field?

Consider blood, saliva and gingival fluid from all dental patients as infective. Refer to "Routine Practices" for preventing transmission of bloodborne infectious diseases.

  • Use rubber dams in restorative dentistry whenever possible.
  • Report immediately suspect fluid exposure, or a needlestick or sharp injury to a designated person because if post-exposure chemoprophylaxis is to be implemented, it should begin preferably within 1 to 2 hours after exposure.

What personal protection should I use?

Wear gloves:

  • If you have open or healing wounds, or skin infections.
  • When in contact with saliva, mucous membranes or blood.
  • When in contact with blood-soiled items, body fluids or surfaces contaminated by them.
  • When examining all oral lesions.

Replace torn or punctured gloves immediately.

Use new gloves for every patient.

Wear gowns:

  • When blood or body fluids are likely to soil clothing.

Change gowns daily or when visibly soiled with blood or body fluids.

Wear masks, face/eye protection or chin-length plastic face shields (with safety glasses or goggles):

  • To protect oral and nasal mucosa from the splatter of blood, saliva or gingival fluid.

Wash hands:

  • Between patients.
  • After completing procedure and before leaving work area.
  • With germicidal soap before and immediately after removing gloves.

When should I decontaminate and sterilize instruments and equipment?

  • Use disposable materials. Dispose in plastic bags. Place needles and sharp instruments in puncture-resistant containers before disposal. Check with local municipality for disposal of contaminated waste.
  • Routinely sterilize instruments used in all dental procedures. Store in sterile packs or pouches.
  • Sterilize after each use other dental instruments that come in contact with oral tissues such as amalgam condensers, plastic instruments of handpieces and burs. High-level disinfect if this is not possible.
  • Cover with impervious-backed paper, tin foil or clear plastic wrap equipment and surfaces that may become contaminated and are not easy to clean. Remove and replace for each patient.
  • Thoroughly clean blood and saliva from supplies used in mouth (impression material, bite registration). Clean and disinfect.

How should I decontaminate of environmental surfaces?

  • Use absorbent paper towelling to remove blood or saliva.
  • Use a medical grade disinfectant to disinfect all potentially contaminated objects and surfaces.
  • Follow safe work procedures as stated in the material safety data sheets (MSDS) for handling and disposal.
