The Sterilization Methods in Dentistry

Since many germs can be transferred simply by touching contaminated surfaces, dentists and dental assistants are typically very fastidious about disinfecting the surfaces in their offices and treatment rooms. Solid surfaces, such as counters and sinks, are generally wiped down with antibacterial spray. Portable folding chairs are also usually covered with disposable paper covers that are discarded after each patient. Dentists and their assistants also usually wear protective barriers, such as gloves and face masks, to help prevent spreading germs to their patients.

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.

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.

Maintain sterilized instruments in the pouches or wrapping in which they were sterilized. 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.

Dry heat sterilizers have been used effectively in dental office for many years. Just as with any other sterilization method, dry heat sterilization is highly dependent upon the operator following the manufacturer’s instructions for cycle time, temperature, instrument packaging, and loading technique. Because dry air is not as efficient a heat conductor as moist heat at the same temperature, a much higher temperature is required for a dry heat unit to accomplish sterilization.

Sterilization in dentistry is very important, and dentists and dental assistants typically clean and disinfect most surfaces in a their offices and treatment rooms to help prevent the spread of germs. 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 a dental 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.
