The Sterilization Methods in Dentistry

Disposable dental supplies are also used whenever possible. Tools that are not disposable are generally scrubbed by hand and placed in a machine known as an autoclave. This machine then disinfects the tools by spraying them with very high-pressure steam, which kills most micro-organisms. Any tools that can not be subjected to high heat or moisture are usually disinfected with chemicals.

Disposable dental tools and supplies are some of the most important items when it comes to sterilization in dentistry. Some disposable dental supplies include bibs and masks wrapped in sterile packaging. Once these are used with one patient, they are simply thrown away.

Maintain sterilized instruments in the pouches or wrapping in which they were sterilized by autoclave sterilizer. If the packaging becomes torn or wet, the items must be repackaged and heat sterilized. Avoid mingling non-sterile packages with sterile ones. There should be a visible indicator, such as chemical indicators or color-change autoclave tape on the outside of each package to allow staff to easily discern sterilized instrument packages from those that have not yet been heat-processed.

Tools that can’t be thrown away, such as dental drills, are generally put through a very intensive dental sterilization process. First they are usually vigorously scrubbed by hand. This is usually done with hot water and detergent, and it helps remove any large particles, such as plaque. They may also be placed in a vibrating tray filled with cleaning solution, which can help remove very small particles.

The Centers for Disease Control and Prevention (CDC), the American Dental Association (ADA), OSAP, most state dental licensing boards, and dental handpiece manufacturers all recommend heat sterilization between patient uses. Virtually all handpieces currently in production are heat-tolerant, and those that are not can be retrofitted to allow heat-processing. Autoclaving and chemical vapor sterilization are considered accepted methods of heat sterilization. High-level disinfection via chemical germicides cannot be biologically monitored to assure sterility. Further, extended contact with chemical germicides may corrode handpiece components.

Sterilization in dentistry also involves killing the invisible germs on tools. Autoclaves are machines that are commonly used during sterilization in dentistry. These machines are usually made from large metal cylinders, and they are similar to pressure cookers. Once the tools are placed in the autoclave, they are sprayed with high-pressure steam. The high pressure inside this machine helps raise the steam to very high temperatures that are necessary for killing disease-causing micro-organisms.
