Study Notes
Surface Disinfection in Dental Treatment Rooms
- Purpose of Disinfection: Prevent patient-to-patient transmission of microorganisms
-
Methods of Surface Contamination Control:
- Surface barriers
- Surface disinfection
- Single-use Items: Reduce patient-to-patient contamination
- Torn Barriers: Require immediate cleaning and disinfection of the underlying surface
- OSHA Blood-Borne Pathogens Standard: Mandates surface disinfection
- Precleaning: Essential to remove bioburden that can interfere with disinfectant effectiveness
- Barrier Placement: Required for surfaces difficult to clean and disinfect
-
Antiseptics vs. Disinfectants:
- Antiseptics: Antimicrobial agents for skin
- Disinfectants: Chemicals for killing microorganisms on inanimate surfaces
- EPA Regulation of Disinfectants: Environmental Protection Agency regulates disinfectant effectiveness
- Ideal Disinfectant: Rapidly kills a broad range of bacteria
- Iodophor Disadvantage: Can leave reddish or yellow stains
- Synthetic Phenol Disadvantage: Can build up and leave a residue
- Sodium Hypochlorite (Household Bleach): A common disinfectant
- Alcohol Disinfectant Limitation: Ineffective in the presence of blood or saliva
- Chlorine Dioxide Uses: Disinfectant or sterilant depending on contact duration
-
Going Green in Dental Offices:
- Reduce waste and chemical use
- Conserve water and energy
- Utilize recyclable packaging
- Implement electronic patient records and digital imaging
- Employ EPA-registered disinfectants
- CDC Carpet and Cloth Furnishing Recommendations: Avoid in dental operatories, laboratories, and instrument processing areas
-
Housekeeping Surface Cleaning:
- Detergent/low-level disinfectant with water
- EPA-registered hospital disinfectant/detergent
Surface Disinfection
- Dental treatment room surfaces must be disinfected to prevent patient-to-patient transmission of microorganisms.
- Surface barriers and disinfection are methods of dealing with surface contamination.
- Barrier placement is required on surfaces that are not easily cleaned and disinfected.
- Single-use items also reduce the risk of contamination.
- If a barrier becomes torn, the surface must be cleaned and disinfected.
- Precleaning is essential before disinfection, as a thin biofilm can inactivate the disinfectant.
OSHA Requirements
- OSHA's Blood-Borne Pathogens Standard mandates surface disinfection.
Disinfectant Types
- Antiseptics are antimicrobial agents used on the skin (not inanimate objects).
- Disinfectants are chemical agents intended to kill microorganisms on inanimate surfaces.
- The EPA regulates disinfectants.
- Ideal disinfectants rapidly kill a broad range of bacteria.
- Iodophors are a type of disinfectant that can leave a reddish or yellowish stain.
- Synthetic phenols can build up and leave a residue.
- Household bleach (sodium hypochlorite) is a common disinfectant.
- Alcohol disinfectants are not effective if blood or saliva are present.
- Chlorine dioxide products can be used as disinfectants or sterilants, depending on the contact duration.
Office Sustainability
- Dental offices can go green by reducing waste and chemicals, using recyclable packaging, and implementing electronic records and digital imaging.
- Using EPA-registered disinfectants is important for environmental sustainability.
CDC Recommendations
- The CDC recommends against carpeting and cloth furnishings in dental operatories, laboratories, and instrument processing areas.
Housekeeping Surfaces
- Housekeeping surfaces should be cleaned with detergent or low-level disinfectant, or an EPA-registered hospital disinfectant/detergent.
