[Barrier protection and disinfection].

The practice of dentistry has changed considerably with the proliferation of infectious diseases. A dentist must integrate new universal aseptic measures in his practice to prevent the spread of these diseases. In the first instance, each member of the dental team must be informed of the risks of contamination and infection inherent with their work. They must be properly trained to know and be able to apply all measures which will minimize any possible risk for themselves and for all their patients. Infection control begins with prevention and consists of using protective barrier techniques which will prevent the spread of infection directly from one person to another. Their use is suggested in order to protect those providing care, as well as, patients from cross contamination. One must reinforce these preventive measures by using corrective techniques which will eliminate contamination agents on all instruments, surfaces and equipment. Everything that cannot be sterilized must be disinfected with disinfectants following recommended procedures which are efficient and protect those providing care.
