How to sterilize dental tools? How to clean and disinfect dental instruments?

In dental treatment, disinfection and sterilization is a very important step, which plays a vital role in the health of both patients and doctors.

Therefore, it is crucial to sterilize dental tool correctly and effectively. This article will introduce you to the

disinfection and sterilization methods of dental tools and the steps for cleaning and disinfection.

There are many methods for disinfection and sterilization of dental tool.

Commonly used methods include high temperature and high pressure sterilization, ethylene oxidation sterilization, ultraviolet sterilization, etc.

The following details some commonly used disinfection and sterilization methods:

Autoclave: This is one of the most common methods of sterilizing dental tool.

It uses high temperature and high pressure environment to achieve effective sterilization.

Dental tool are usually placed in a special high-temperature and high-pressure sterilizer and subjected to

high-temperature and high-pressure treatment for a certain period of time to kill bacteria, viruses and fungi.

Ethylene oxidation sterilization: Ethylene oxidation sterilization is a chemical sterilization method that uses the sterilization effect of ethylene oxidation gas to perform disinfection and sterilization.

Ethylene oxidation sterilization can achieve a high degree of sterilization and is suitable for all types of dental instruments, including nickel-chromium alloys.

Ultraviolet sterilization: Ultraviolet sterilization is a method that uses ultraviolet rays to irradiate bacteria and viruses to lose their biological activity and reproductive ability.

This method is simple and fast to operate, and has a good sterilization effect on instruments.

However, it should be noted that ultraviolet sterilization can only irradiate the surface area that ultraviolet rays can reach, and cannot achieve the sterilization effect inside complex instruments.

The above are several common methods for disinfection and sterilization of dental tools. Dentists will choose the most suitable method according to the specific situation.

In addition to disinfection and sterilization methods, cleaning and disinfecting dental instruments is also

very important. Here are the steps for cleaning and disinfecting dental instruments:

Pretreatment: the initial cleaning of dental tool before disinfection and sterilization.

This step is to remove blood, saliva and other substances on the surface. You can use general detergents or washing utensils for cleaning.

Thorough cleaning: Cleaning tools require special cleaning agents and use a cleaning brush to scrub.

During the brushing process, thoroughly clean the surface and interior of all dental tool. And try to avoid

cross-contamination of dental tool during the cleaning process.

Disinfection and sterilization: Disinfect and sterilize the dental instrument and the selected sterilization

and sterilization method. Depending on the sterilization method, the dentist may place the dental tool in

a special sterilizing device or use specific medications to sterilize the tools.

Packaging and storage: Sterilized dental tool should be placed in sealed packaging bags with the sterilization date and expiry date marked.

This keeps tools sterilized and prevents recontamination.
Disinfection, sterilization, cleaning and disinfection of dental tool are important aspects to protect the health of patients and the safety of dentists.

Only by rationally selecting appropriate disinfection and sterilization methods and strictly implementing cleaning and disinfection steps can the efficient sterilization and safe use of dental instruments be ensured.

Everyone should pay attention to the disinfection and sterilization of dental instruments and operate them correctly under the guidance of the dentist to ensure the safety and effectiveness of dental treatment!
