Did You Know That Aerosols Can Contaminate The Environment in Dental Sterilization Rooms?

Microbial aerosol is a special kind of aerosol, a colloidal system formed by microorganisms suspended in the air, including viruses, bacteria, fungi, and their by-products. Viruses are the smallest microorganisms, with a diameter of 0.02~0.3μm, although they can only reproduce in host cells, but in the absence of host cells, they can still be attached to droplets such as respiratory secretions to form viral aerosols, which lead to infectious diseases through airborne transmission; bacterial aerosols are usually present alone or carried by other particles, and pathogenic bacteria are easy to pose a hazard to human health; Fungal aerosols often occur in humid environments; molds and other molds in indoor environments can lead to asthma, allergic rhinitis, and so on. Microbial aerosols can enter the human respiratory system as fine particles do, and are retained or settled in the respiratory tract or even in the lungs, and their biological activity makes microbial aerosols a greater threat to humans than ordinary aerosols.

Because the human mouth contains a large number of bacteria and viruses, dental instruments often come into contact with bacteria and viruses during treatment. According to the conventional disinfection process, after collecting these contaminated instruments, the nurse in the sterilization room will go to the cleaning room for cleaning, and then put them into the drying oven for drying treatment before putting them into the sterilizer for thorough sterilization. However, the cleaning process in the previous sequence does not effectively kill these bacteria and viruses. Because the drying oven is to use internal and external air heat exchange for drying, when these instruments in the drying oven for drying, viruses and bacteria will be in the form of aerosols, gradually diffuse into the air of the entire cleaning room, endangering the health of nurses in the sterilization room.

The YESON TSD sterilizer's unique drying process can completely replace the drying box, so that instruments can be packed into the sterilizer directly after cleaning without the need for drying in the drying box. And YESON TSD sterilizer drying belongs to the closed drying, inside and outside the air does not convection, effectively preventing aerosol pollution of the indoor environment, to better protect the health of nurses in the sterilization room.
