How to Clean Dental Handpieces

when cleaning a dental handpiece it is important to clean the outer part of the handpiece to prevent contamination of the inner side of the handpiece. First, you need to remove any dental burs from your high speed handpiece/low speed handpiece, then rinse the handpiece with procedural water for 20 seconds. Third, you use the lint-free, pre-soaked, non-protein fixing disinfection wipe to wipe down the external surface of the dental handpiece. When it is done, use the lockable transport box to transport them to the decontamination room.


Do not put the dental handpiece submerge in water, an ultrasonic bath, or any cleaning agent.

Disinfection Inside the Handpiece

After the initial external cleaning of the dental handpiece, the next crucial step is the internal disinfection process. There are two primary methods utilized for this purpose, which are detailed below.

Washer Disinfector

The washer-disinfector has proven that it is an efficient method to reduce contamination. But when you use it, a few things need to be aware of.


You need to strictly follow the instruction of the manufacturers' guidelines because not all implant handpiece and dental handpiece are suitable for use in a washer disinfector.

You should place the dental handpiece on the handpiece stand.

How to Sterilize the Dental Handpiece

It's important to distinguish between sterilization and disinfection. Disinfection is the process of eliminating most pathogenic microorganisms (excluding their spores) from surfaces or objects. Sterilization, however, goes a step further by eradicating all forms of microbial life, including spores, from the dental handpiece.

The most commonly used and acceptable methods to sterilize the 4 hole high speed handpiece and low speed handpiece include chemical vapor sterilizers, dry heat, and autoclave.





How to Lubricate the Dental Handpiece

There are three effective methods for lubricating dental handpieces, including surgical straight models. The initial method involves using an aerosol spray to deliver lubricant directly to the turbine or low-speed motor components. Alternatively, a pin needle dropper can be employed for precise application of lubricant to the handpiece.

If you want to use these two methods, you need to be aware of running that handpiece after lubrication to ensure the lubricant can reach each component of the handpiece. By the way, you also need to clean the extra oil on the dental handpiece holder, to ensure the cleaning of the dental handpiece.

And, the third method is to use the automated handpiece cleaning system. Like the midwest automate handpiece maintenance system, it could do all of the cleaning work for you when you place the handpiece properly into the cleaning system.


All in all, the cleaning, disinfection, and sterilization of the low speed handpiece and dental high speed handpiece led are one of the most useful ways to maintain their normal function and avoid cross infection.
