In oral treatment, the drainage dental handpiece is the most commonly used device, and the function and structure of the dental handpiece are complicated. Due to the many internal pipelines and cavities, the patient’s mouth, saliva, and various debris will splash and contaminate the phone during use. At the same time, the negative pressure generated when the operation is stopped will also enter the blood, saliva and debris. Inside the crumbs, suck back inside. If the dental handpiece is not cleaned thoroughly, the dirt retained in the interior of the dental handpiece, raw materials, etc., will become solid after being inactivated by high temperature, so the fouling matter will adhere to the tube wall, bearings and balls, etc., which will affect the performance of the dental handpiece. And lifespan, which will affect the effectiveness of the dental handpiece infection is a serious infection. This small class will explain in detail the cleaning and maintenance steps of the drainage dental handpiece.
Maintenance Step:
1. Remove the dental handpiece from the quick interface or cable, and remove the bur.
2. Remove the dental handpiece from the quick interface or cable, and remove the bur.
3. Take the cleaned dental handpiece out of the cleaning machine and dry its interior with a pressure air gun.
4. Connect the dental handpiece to the matching oil injection adapter or connector and insert it into the automatic oil injection maintenance machine for oil injection. Choose a suitable oiling program.
5. Pack the dental handpiece after oil injection.
6. Perform pressure steam sterilization on the dental handpiece.
FAQ:
Q: Why do dental handpieces need to be thoroughly cleaned before sterilization?
A: The dental handpiece enters the patient’s mouth directly and is in close contact with the saliva, blood, gingival crevicular fluid and dental plaque in the mouth. When the dental handpieces stops rotating, the air in the head of the dental handpieces is under negative pressure. This negative pressure can cause the saliva, blood, microorganisms, cutting debris and other pollutants in the patient's mouth to be sucked back into the dead corners and water and air ducts inside the dental handpieces. If it is not cleaned, the blood stains, grease stains and other dirt remaining in the internal cavities and gaps of the dental handpieces will be easier to form biofilms after high temperature and high pressure sterilization, thereby preventing effective contact between microorganisms and gases, causing sterilization failure.
Q: Can the oil injection curing machine replace the cleaning machine?
A: The important role of cleaning is to remove all visible dirt, tissues, blood stains and other organic matter to ensure the effect of sterilization. For dental handpieces that do not use a cleaning machine, the oil injection curing machine alone cannot effectively remove the dirt inside and outside of the dental handpieces and the microorganisms (film) on the pipe wall, so that the oil film of the oil injection curing machine cannot contact the dental handpieces well, and the dirt will accumulate more and more. As a result, cross-infection is caused, and the damage rate of dental handpieces will also increase.

Q: Can the dental handpieces that is not cleaned be directly sterilized by high temperature and high pressure? What is the result?
A: Studies have shown that it is easier to form a biofilm in the inner cavity of the dental handpieces if it is not cleaned. The time required for complete sterilization of the bacterial spores wrapped by the biofilm in a pressure steam environment at 134°C is 150 minutes. Three times of pre-vacuum sterilizer working time (3-4 minutes), the sterilization will not be complete, which will cause sterilization failure, thereby increasing the probability of subsequent infection of patients.
