Dental Laboratory Hygiene

All members of staff must be committed to working in an infection free and safe working environment. This can be achieved in a number of ways:

· Personal hygiene.

· Staff training. There should be a program of staff training in matters relating to health and safety, it is as important as training in the use of equipment and techniques.

· The employer should ensure that all necessary safety equipment and barrier clothing is supplied to staff.

· Staff should not eat or smoke at workbenches.

· It should be encouraged that all staff be inoculated against hepatitis B and influenza.

All materials transported into and out of the dental laboratory should be decontaminated, disinfected and placed into a sealed container.

An area should be set aside to receive incoming jobs. When opening work gloves, mask, glasses and apron should be worn. If required, impressions and jobs should be decontaminated and disinfected. The procedure involves rinsing the job under running water and soaking in a neutral detergent. Dental impressions are contaminated with saliva and sometimes blood. That's why jobs which have already been inserted into the mouth require special attention, e. g. wax bites, try-ins, metal copings and repairs. Any instruments or materials (such as spatulas, wax knives and carvers, tweezers, face-bow parts) which have been in contact with jobs need to be cleaned and disinfected. What cannot be heat sterilized must be chemically treated.

Other features to be considered include:

· Sufficient space to divide the lab into specific work areas, e. g. work area, receiving area, wet area etc.

· Adequate water, with preferably automatically operating taps.

· Natural light.

· Enough ventilation. There should be a constant flow of air so that dust, fumes and heat produced from some laboratory procedures may be removed. Air conditioners which can harbour dangerous microorganisms need to be regularly cleaned.

· Covered bins for receiving waste materials.

· Impervious flooring. Floors should be covered with impervious, moisture resistant material, such as continuous vinyl.

· A similar quality of workbench areas. They must be hard, smooth and easy to clean (stainless steel is a good choice).

· All fixtures and fittings should be designed to allow for easy cleaning and to discourage the accumulation of dust.

· Separate areas for staff changing rooms should be available.

· Food and eating areas should be separate from the changing rooms.
