What is the recommended practice when operating an ultrasonic cleaner?

The recommended practice of covering an ultrasonic cleaner before operation serves multiple purposes that enhance both safety and efficacy. First and foremost, covering the unit helps to minimize aerosol and mist production, which can contain potentially infectious materials. This is crucial in a dental setting where infection control is paramount.

Additionally, covering the ultrasonic cleaner helps maintain the temperature of the cleaning solution, which can enhance the cleaning process. A stable temperature allows for more effective cavitation, the process responsible for dislodging debris from instruments.

Moreover, a cover protects the cleaner from external contaminants and helps prevent evaporation of cleaning solutions, ensuring that the cleaning properties remain effective throughout the operation. This practice aligns with infection control protocols and helps ensure a safe working environment for dental professionals and their patients.
