In Dentistry, critical instruments are those used to penetrate soft tissue or bone, or enter into or contact the bloodstream or other normally sterile tissue. They should be sterilized after each use. Sterilization is achieved by various methods. Traditional sterilization methods are often time consuming for practical use. Today's sterilizers are sophisticated, automatic, and computerized devices that accurately execute programmed jobs, creating uniform conditions inside pressure vessels to achieve sterilization. Specialized knowledge is necessary to ensure that the right cycle is selected; this requires an educated and competent operator. Sterilization practices, standards and products are changing in the health care system and continues to undergo dramatic restructuring. The causes of this restructuring are hospital consolidations, implementation of diagnostic-related-group reimbursement, cost-containment programs, and increasing acceptance of disposable packs.
