Prior to Seating the Patient

  1. Open and Clean the Suction Trap:Using gloves turn the suction off and open the trap to clean the screen.  This can be accomplished using a toothbrush and running water.  The lines should be flushed with an intermediate to high non-corrosive disinfectant.  A semi-synthetic phenolic is acceptable.  Do not use sodium hypochlorite or glutaraldehyde.


  2. Wipe of all surfaces of gross debris using a moist paper towel.Prior to each patient all surfaces in the dental operatory that can be considered non-critical should be wiped with clean moist paper towels to remove gross debris.  Non-critical surfaces are those areas that do not ordinarily contact the patient directly.  Examples include chair handles, light handles, x-ray machines, bracket tables, chair back, counter tops and others.


  3. Surface Disinfection:Once the gross debris has been removed the non-critical surfaces should be sprayed lightly with a intermediate to low surface disinfectant.  A semi-synthetic phenolic is acceptable.  The surface should be wiped dry , sprayed lightly again and allowed to dry.


  4. Remove Gloves:Once the non-critical areas have been disinfected you remove your gloves and wash your hands immediately.


  5. Surface Barriers:Cover all those non-critical areas that are unable to be easily disinfected.  The use of plastic bags in an appropriate manner can be accomplished quickly and easily.  Do NOT  use tape to attach plastic or other coverings.  Flat surface areas that are non-critical can be covered with non-porous paper to protect the surfaces.


  6. Headrest Covers:The use of large plastic bags instead of normal headrest covers will cover and protect the back of the chair.  The large cover will also protect the switches of the chair and enable the operator to adjust the chair without contaminating the field.


  7. Saliva Ejectors and High Speed evacuation Tips:Saliva ejectors and high speed evacuation should NEVER be reused.  They should be disposed of between each patient.


  8. Handpieces:Prior to a procedure the high speed handpiece should be flushed for 30 seconds.


  9. Instruments:Prior to seating the patient all instruments needed for treatment must be accessible.  Instruments used in the deliver of dental care should be considered critical items.


  10. RadiographsPrior to seating the patient, all pertinent radiographs should be placed on the view box and the patient chart placed away from the area of contamination.  Charts should be readily available


  11. Gloves, Mask, and Protective Eyewear:Place a pair of gloves, a mask, and protective eyewear in the operatory.  These are to be worn once the patient is seated and properly positioned.
