What Are the Most Common Methods of Sterilization in Dentistry?

Dental burs are one of the most important accessories for dental drills. They consist of a needle and a shank. There are two main ways for dental burs to cause cross infection: one is the surface contamination caused by the burs in contact with the patient's saliva, blood, and debris during the oral operation; the second is the pathogens that remain in the texture during the treatment Microorganisms and so on. There are many patients in the dental clinic, and the fluidity is high, and the use rate and turnover rate of burs are very high. How to better avoid cross infection is one of the important contents of dental care.

Dental bur

First sterilize the used bur for 30 minutes, and the disinfectant is 2% glutaraldehyde. After soaking, use a small-toothed toothbrush to clean the textured part of the bur, and then rinse with water.

Because the needle is operated in the patient's mouth, and often comes into contact with saliva, blood, and mucosal tissues, the choice of disinfectant is more stringent. It should choose a disinfectant with good sterilization effect, irritant and less corrosive to metals. Tan Chengzhu and others No dental bacteria and HBsAg were detected in the dental burs immersed in 20ml / L glutaraldehyde for 30min. At present, we clinically use 20mg / L glutaraldehyde and other chemical disinfectants for disinfection of burs.

Cleaning and disinfection of burs is very important. Because it is related to protecting the health of doctors and patients and preventing cross infection, the cleaning and disinfection of dental burs is based on the current use of "one person, one machine" for dental mobile phones, and it is necessary to promote the work of "one person, one special bur". Should fully arouse the attention of the majority of medical staff.
