[Sterilization and quality control].
The dental profession has always considered the sterilization of surgical instruments as an important element in the prevention of infection. During the last decade the concern with blood and to a lesser degree with saliva in the transmission of infection, due primarily to the hepatitis and HIV viruses, has resulted in many corporate organizations releasing recommendations to reinforce the use of sterilization techniques and disinfection techniques when sterilization is not applicable or justifiable. As a result of the fact that the two terms are often intermingled, the authors review the fact that each one pursues different objectives and put the emphasis on sterilization by briefly reviewing the principal advantages and disadvantages of each method of sterilization presently available for use in dental offices. Subsequently, they stress the importance of introducing quality control in any infection prevention program, in order to assure that the sterilization process is not at the mercy of human error or mechanical failure. The pharmaceutical industry, food chains and hospital centres have for more than 40 years realized the importance of using chemical indicators and especially biological testing. Only biological testing can put one's mind at ease, for the professional in a dental office and the patient receiving care, that the instruments or objects that one comes in contact with are truly sterile. The dental profession did not wait for the discovery of the hepatitis B and HIV viruses to become preoccupied with the spread of disease and have sterilized their surgical instruments for many years.(ABSTRACT TRUNCATED AT 250 WORDS)
