What is the primary aim of using a washer-disinfector in dental practice?

The primary aim of using a washer-disinfector in dental practice is to clean and disinfect items. This equipment is designed to automate the cleaning process of dental instruments and ensure they are free from contaminants such as blood, saliva, and other debris. The washer-disinfector uses a combination of water, detergent, and controlled thermal disinfection to achieve this.

While sterilization is a critical part of infection control in a dental setting, it is a separate process that typically occurs after items have been cleaned and disinfected. Sterilization ensures that all microorganisms, including spores, are destroyed, which is not the sole function of a washer-disinfector. Unlike storage or packaging, which are important in the overall management of dental instruments, the washer-disinfector's focus is on preparing instruments for subsequent sterilization or use by ensuring they are properly cleaned and disinfected.
