Does a Dental High Speed Handpiece need to be sterilized?
The working principle of the dental high speed handpiece is based on the combination of air pressure and motor drive to provide efficient cleaning of tartar and plaque. In this process, water, as one of the cleaning media, is mixed with air and sprayed onto the tooth surface by a high-speed rotating nozzle. This mixed fluid can more effectively penetrate and wash the dirt on the surface of the teeth, improving the cleaning effect.
As a special treatment instrument for stomatologists, high-speed dental handpieces directly touch the patient's mouth during use, so there is a high risk of cross-infection. In order to ensure the safety of patient treatment and prevent the spread of disease, dental high-speed handpieces must be strictly cleaned, disinfected and sterilized after use.
In the dental treatment process, it is essential to prevent cross infection. Dental high-speed handpieces may come into contact with patients' saliva and body fluids during use, which may contain germs. Using water as a cleaning medium can help flush out these potential sources of contamination and reduce the risk of cross-infection. At the same time, regular washing and disinfection of the dental chair water system is also one of the important measures to prevent cross infection.
What is the disinfection process of dental high-speed handpieces？
Preliminary cleaning: After the end of use, the water and air routes inside the dental handpiece should be washed in time to remove surface pollutants and debris. This can be done through the water and air system of the dental integrated treatment table, and the irrigation time is generally not less than 30 seconds.
Manual cleaning: Remove the dental handpiece from the fast connector or cable, remove the needle, and wipe the visible stains on the surface of the handpiece with a wet cotton ball. Then, the dental handpiece is cleaned under running water to remove surface contaminants.
Enzyme cleaner soak: For a more thorough cleaning of the dental handpiece, you can use enzyme cleaner soak. Soak your dental handpiece in an enzyme cleaner for 2-5 minutes, then scrub or use an ultrasonic cleaner to clean it.
High-pressure water gun flushing: For the lumen inside the dental handpiece, a high-pressure water gun or syringe should be used to flush the lumen to ensure that contaminants are completely removed.
Distilled water rinse and dry: Rinse the dental handpiece with distilled water to remove residual cleaning agent. Then, use a high-pressure water gun or syringe to dry the water on the surface of the pipe and wind wheel bearing.
Disinfection and sterilization: Disinfection and sterilization is a key part of the dental handpiece cleaning process. The inside and outside surfaces of the dental handpiece can be disinfected with 75% ethanol, and then sterilized with an autoclave. The sterilization temperature and time should be strictly controlled to ensure the sterilization effect.
Oil lubrication: In order to extend the service life of the dental handpiece and maintain its good working condition, it should be injected with oil lubrication after sterilization. Professional handpiece lubricating oil should be used when filling oil, and ensure that the lubricating oil is evenly covered in the bearing ball and wind wheel shaft.
Packaging and storage: Dental handpieces after disinfection and sterilization should be sealed in paper-plastic sheet packaging and marked with sterilization date and expiration date. It is then stored in the sterile items storage area for next use.
To sum up, dental high-speed handpieces must be strictly cleaned, disinfected and sterilized after use. This is not only to ensure the safety of the patient's treatment, but also to prevent the spread of the disease and the occurrence of cross-infection. Therefore, dental medical institutions should establish a sound dental handpiece cleaning disinfection and sterilization system, and operate in strict accordance with the norms.
Conclusion
As a key tool in oral therapy, the disinfection of high-speed handpieces during use is very important. In summary, dental high-speed handpieces do need to be disinfected.
First of all, from the point of view of preventing cross-infection, dental high-speed handpieces will be in direct contact with the patient's saliva, blood and other body fluids during use, which may contain pathogenic microorganisms, such as bacteria, viruses and so on. If the dental high-speed handpiece is not strictly disinfected, these pathogenic microorganisms may cause cross-infection when the next patient uses it, seriously threatening the health and safety of patients.
Secondly, from the perspective of protecting the safety of patients and medical personnel, disinfection is an important measure to ensure the sterility of dental high-speed handpieces. Sterile dental high-speed handpieces reduce the risk of patients contracting diseases from the use of unsterilized or inthoroughly sterilized instruments, while also protecting medical personnel from pathogenic microorganisms and maintaining their occupational health.
Moreover, from the point of view of improving the treatment effect, disinfection can ensure that the dental high-speed handpiece is in good working condition before each use. Sterile dental high-speed handpieces can more effectively remove dirt and plaque from tooth surfaces, improving treatment outcomes and patient satisfaction.
Therefore, dental high-speed handpieces need to be strictly cleaned and disinfected after each use. Medical institutions should establish a sound disinfection system and process, and adopt appropriate disinfection methods and equipment to ensure the disinfection quality of dental high-speed handpieces. At the same time, medical personnel should also strictly abide by disinfection norms to ensure that each patient can use a safe and sterile dental high-speed handpiece.
