introduction and cleaning of dental bur

As we all know, the cleaning and disinfection of burs are very important. At present, we clinically use chemical disinfectants such as 20mg/L glutaraldehyde for the disinfection of burs.

Introduction of Dental Bur

Dental bur is one of the important accessories of a dental drill, which consists of a needle head and needle handle. There are two main ways of cross-infection caused by dental burs: one is the surface contamination caused by the contact of the bur with the patient's saliva, blood, and debris during the operation in the oral cavity; the other is the pathogens like Microorganisms retained in the texture of the bur during the treatment process.

Disinfection Methods of Dental Bur

First, the used burs are disinfected by soaking for 30 minutes, and the disinfectant is 2% glutaraldehyde. After soaking, use a toothbrush with a small head to clean the textured part of the bur, and finally rinse it with clean water.

Because the bur is operated in the patient's mouth and often contacts saliva, blood, and mucosal tissue, the selection of disinfectants is more stringent. The disinfectant with a good sterilization effect, less irritation, and less corrosiveness to metals should be selected. For example, there are no bacteria and HBsAg for dental burs soaked in 20ml/L glutaraldehyde for 30min.

So in order to protect dental patients, how to better avoid cross infection is one of the important contents of dental care. Because it is related to ensuring the health of doctors and patients and preventing cross-infection, the cleaning and disinfection of dental burs are based on the current "one person, one machine" and it is necessary to promote the work of "one person, one special bur". Every medical worker should pay attention to this.
