How do you sterilize a comprehensive dental treatment machine? See what comprehensive dental treatment machine suppliers have to say

2023-02-09

The supplier of dental comprehensive treatment machine said that when using dental comprehensive treatment machine, the equipment should be cleaned and sterilized regularly to clean the dirt and biofilm attached to the inner wall of the pipeline, to prevent the pipeline from the secondary pollution of the water used for diagnosis and treatment and to control the total number of bacterial colonies. So, do you know how to sterilize the dental comprehensive treatment machine? Let's take a look at the introduction of dental comprehensive treatment machine supplier.

　　1、 Relevant reference standards and norms

　　The supplier of dental comprehensive treatment machine said that the total number of bacterial colonies in the internal medical water of dental comprehensive treatment machine should not be more than 100 cfu/ml. the feed water should be selected at least in line with GB5749 drinking water, and the water treated by the water treatment device as the feed water, so as to solve the problem of the total number of bacterial colonies in the medical water of the dental comprehensive treatment machine exceeds the standard.

　　2, dental comprehensive treatment machine traditional sterilization method analysis

　　Dental comprehensive treatment machine supplier said, dental comprehensive treatment machine water disinfectant selection should follow the principle of low toxicity, no odor, easy to degrade, no significant impact on the characteristics of the water organ. You can choose chlorine disinfectant, ozone, peroxide and so on.

　　Disinfectant: The supplier of dental comprehensive treatment machine said that chlorine disinfectant has good disinfection effect, low price and low cost of use. It can be used for pipe disinfection and water disinfection, and can effectively reduce the number of bacteria in the comprehensive dental treatment table. However, some studies have shown that after chlorine disinfection, the bonding performance of dentin is reduced, the small radius of chlorine ions and strong penetration can destroy the passivation film on the metal surface, accelerating local corrosion (such as pipe penetration corrosion), and the odor and toxicity of chlorine-containing disinfectants (mutagenicity) have always been a major defect. Currently, the use of chlorine is gradually being restricted and reduced worldwide.

　　Ozone: Ozone (O3), also known as "oxygen-enriched water", has excellent disinfecting and sterilizing properties, and has a rapid bactericidal effect on bacteria, according to the supplier of comprehensive dental treatment machines. Ozone is soluble in water and can also be used to disinfect water pipes. However, ozone is not stable in water and is easily emitted and decomposed. When the ozone content exceeds 25%, it can easily explode. Currently, the permissible concentration of ozone is 0.2 mg/m3, and it is difficult to ensure the disinfection effect with this low concentration. Excessive ozone concentration can jeopardize human health. The higher the concentration in water, the easier it is for ozone to diffuse into the air, causing indoor ozone pollution in the examination room.

　　Peroxides: Peroxides, which mainly include hydrogen peroxide and hydrogen peroxide, have a strong bactericidal effect and will not be decomposed by acetic acid and oxygen after action. They have a strong odor and strong corrosiveness, not applicable to metal pipes. The supplier of comprehensive dental treatment machine said that hydrogen peroxide is an ideal disinfectant, which can be decomposed into water and oxygen after action, without residue, and can disinfect pipelines and water bodies, but there are some disadvantages, such as unstable efficacy, temperature, and PH value. The effect is not stable due to the influence of light and other factors.
