We are very concerned with infection control and have therefore followed the recommendations of ADA Council on Scientific Affairs, ADA Council on Dental Practice and the Centers for Disease Control (CDC). The procedures used are termed “Universal Precautions”. Since not all patients with infectious diseases can be identified by medical history, physical examination or readily available laboratory tests, the CDC has introduced the concept of universal precautions. This term refers to a method of infection control in which all human blood and certain humanbody fluids (saliva in dentistry) are treated as if known to be infectious for HIV, HBV and other bloodborne pathogens.Universal precautions means that the same infection control procedures are used for all patients. The following details the steps for the lab and the table shows the materials used.
Receiving area: A receiving area should be established separate from the production area. Countertops and work surfaces should be cleaned and then disinfected daily with an appropriate surface disinfectant used according to the manufacturer's directions.
Incoming cases: All cases should be disinfected as they are received. Containers should be sterilized or disinfected after each use. Packing materials should be discarded to avoid cross contamination.
Disposal of waste materials Solid waste that is soaked or saturated with body fluids should be placed in sealed, sturdy, impervious bags. The bag should be disposed of following regulations established by local or state environmental agencies.
Production area: Persons working in the production area should wear a clean uniform or laboratory coat, a face mask, protective eyewear and disposable gloves. Work surfaces and equipment should be kept free of debris and disinfected daily. Any instruments, attachments and materials to be used with new prostheses or appliances should be maintained separately from those to be used with prostheses or appliances that have already been inserted in the mouth. Ragwheels can be washed and autoclaved after each case. Brushes and other equipment should be disinfected at least daily. A small amount of pumice should be dispensed in small disposable containers for individual use on each case. The excess should be discarded. A liquid disinfectant (1:20 sodium hypochlorite solution) can serve as a mixing medium for pumice. Adding three parts green soap to the disinfectant solution will keep the pumice suspended.
Outgoing cases: Each case should be disinfected before it is returned to the dental office. Dentists should be informed about infection control procedures that are used.
