The Role Of A Sterilizer And Its Importance In Dental Reprocessing

The role of the sterilizer in dental reprocessing goes in line with the success of any dental team. Without a reliable sterilizer, it could be challenging to maintain a large inventory of instruments or the time-consuming process of cleaning them all by hand.

A sterilizer is a machine that uses steam under pressure to kill microorganisms. Sterilizers are used in dental offices to sterilize instruments and materials.

A sterilizer, also known as an autoclave, uses either an internal chamber or an external chamber to sterilize items. An internal chamber is where the items to be sterilized are placed. The internal dental chamber is then sealed and pressurized with steam. The steam penetrates the items in the chamber, killing any microorganisms present.

External sterilizers have a separate compartment for the instruments and materials to be sterilized. This type of autoclave uses a pump to circulate steam outside the chamber. The steam then penetrates the items in the chamber, killing any microorganisms present.

How Does a Sterilizer Work?

Sterilizers work by using steam to kill harmful bacteria and viruses. The steam is generally generated by boiling water, and the pressure inside the sterilizer keeps the water from boiling. The instruments and materials to be sterilized are placed in a chamber inside the sterilizer. The chamber is then sealed, and the steam is turned on.

The steam penetrates the instruments and materials, killing any bacteria or viruses that may be present. The sterilizer then goes through a cooling cycle before the door is opened. Once the door is opened, the sterilized instruments and materials can be removed and used on patients. For more updates, visit:

What are the Kinds of Sterilizers?

Two types of sterilizers are commonly used in dental offices: the gravity displacement sterilizer and the pre-vacuum sterilizer. The gravity displacement sterilizer uses steam to displace the air in the chamber, while the pre-vacuum sterilizer uses a vacuum to remove the air before sterilization.

Why and how often should a dentist clean dental equipment with sterilizers?

One of the best ways to clean and sterilize dental equipment is by using a sterilizer. Sterilizers use high pressure and steam to sterilize equipment. They are the most effective way to destroy bacteria, viruses, and spores.

How often to clean dental equipment with sterilizers depends on how often the equipment is used. If used daily, it should be sterilized at the end of each day. If it is used less frequently, it can be sterilized between uses. However, if there is any visible dirt or debris on the equipment, it should be cleaned before sterilization.

Cleaning and sterilizing dental equipment are essential because it helps to prevent the spread of infection. 


A sterilizer is a critical piece of equipment in dental reprocessing. It sterilizes instruments and materials, ensuring that they are safe to use. Proper sterilizer operation is essential to protect patients and staff from cross-infection. Sterilizers can be complex, and in general, the sterilizer is operated according to a procedure or protocol.

A common example is a “closed-system sterilization cycle,” in which steam penetrates sealed bags containing instruments and other items to be sterilized. After the cycle ends, the sterilizer will be opened to vent excess pressure and closed again. This ensures that all of the items are sterilized properly.

For some dental procedures, it is also critical that instruments be kept at an appropriate temperature after being sterilized in the sterilizer. In this case, they are placed in an instrument warmer until they reach the proper temperature before being used on patients.
