Explore how ultrasonic cleaners enhance dental instrument hygiene and prevent cross-contamination. Find the best solutions for infection control in dental clinics at this article.
Update: 2025-06-12 | Industry News
In dental procedures, various instruments such as dental handpieces, forceps, and endodontic tools come into direct contact with a patient's oral tissues, blood, saliva, and other fluids, making them susceptible to pathogen contamination. If cleaning is inadequate, residual bacteria, viruses, fungi, and other pathogens can spread to other patients during the next procedure, leading to cross-contamination risks such as hepatitis B, HIV, syphilis, and other blood-borne diseases. Therefore, thoroughly cleaning medical instruments is the primary step in preventing cross-infection. That's why using an ultrasonic cleaner for medical instruments is the best practice.
In the disinfection and sterilization process of dental instruments, ultrasonic cleaning typically serves as a pre-treatment step to remove large amounts of debris from the instrument surface, providing a solid foundation for subsequent disinfection and sterilization. Additionally, for instruments that are used directly, such as disposable instruments that need cleaning before use, ultrasonic cleaning can also be employed as the final cleaning step to ensure the instruments meet cleanliness standards.
Ultrasonic technology is powerful and can penetrate deep into the fine crevices, blind holes, grooves, and other parts of the instruments that are difficult to reach with traditional hand cleaning. By utilizing the cavitation effect, acceleration effect, and direct flow action of ultrasound in liquid, contaminants are dispersed, emulsified, and stripped away, achieving a high level of cleanliness.
When selecting an ultrasonic cleaner for dental medical instruments, three key factors should be considered: performance, functionality, and compliance.
Choose a model with heating capabilities, as water temperatures between 40-60°C can enhance the activity of cleaning agents. Additionally, consider the tank capacity; small clinics may opt for 6- 10 L models, while larger institutions should consider 15 L or more.
Special cleaning baskets should be used for different instruments such as dental handpieces and endodontic tools to ensure even placement, preventing direct contact with the tank's bottom, which could damage the instruments. Furthermore, the ultrasonic cleaner should be made of stainless steel to ensure corrosion resistance, and it should ideally be ISO 13485 certified for medical devices, ensuring it meets industry standards.
Dental handpieces are among the most commonly used instruments in dentistry. Their internal structures, including turbines, bearings, pipes, and threads, can accumulate debris, saliva, and blood. Ultrasonic cleaning can reach the interior cavities and pipelines to remove residual contaminants, maintaining the handpiece’s performance and extending its lifespan.
Root canal files, reamers, and other tools used in root canal therapy can carry pulp tissue, dentin fragments, and bacteria after use. Ultrasonic cleaning effectively removes these residues, laying the foundation for successful root canal treatment.

Instruments like impression trays and wax carving knives may accumulate plaster, impression materials, and other debris during dental restoration procedures. Ultrasonic cleaning can easily remove these impurities, ensuring the instruments remain clean.
Brackets, archwires, and other orthodontic devices, along with their installation tools, can gather food particles and bacteria during use. Ultrasonic cleaning is ideal for thoroughly cleaning these small, delicate instruments to maintain oral hygiene and treatment effectiveness.
Ultrasonic cleaning gently removes dirt and residue from the surfaces of dental implants, porcelain crowns, and bridges, preserving their smooth finish without causing surface damage.
Before ultrasonic cleaning, remove visible large debris such as tooth fragments and plaster. If instruments have dried blood or bodily fluids, soak them in an enzymatic cleaner for 10-15 minutes to soften the residue.
Select a cleaning agent based on the instrument material and the type of contamination. Options include neutral, alkaline, acidic, or enzymatic cleaners, and ensure the concentration matches the manufacturer’s instructions.
Adjust the cleaning time (10-30 minutes) and temperature (40°C-60°C) based on the type of instrument and cleaning requirements.
Place the pre-treated instruments in the cleaning basket, ensuring enough space between them to avoid overlapping. Submerge the basket in the tank with the appropriate cleaning solution, cover the tank, and activate the machine as per the preset parameters.
Treatment: After cleaning, rinse the instruments with clean or distilled water to remove any remaining cleaning solution. If sterilization or disinfection is required, proceed with the next steps promptly. Regularly clean and disinfect the tank and baskets.
