Dental autoclaves are machines that are commonly used during sterilization in dentistry, 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 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.

High-level disinfection via chemical germicides cannot be biologically monitored to assure sterility. For instance, sterilization is a necessary part of the maintenance of your dental handpiece. This process also puts your handpiece under the most stress with wear and tear. Maximum temperatures in your autoclave shouldn’t reach more than 140 degrees Fahrenheit. This can help to preserve your handpiece just a bit longer in between the need for service.

Since many germs can be transferred simply by touching contaminated surfaces, 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.

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.

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.

Any devices that can not be subjected to moisture or intense heat must be sterilized with other methods. Chemicals are often used during sterilization in dentistry as well. Some of the chemicals used to kill germs and sterilize dental tools are typically iodine or alcohol based, since both of these chemicals are very effective at killing germs.
