What is the primary purpose of cleaning in a dental healthcare setting?

The primary purpose of cleaning in a dental healthcare setting is to remove visible soil and contaminants from surfaces. Cleaning is an essential first step in infection control, as it helps to ensure that surfaces are free from debris, blood, saliva, and other organic materials. This step is crucial because contaminants can shield microorganisms from disinfectants and sterilants, making subsequent disinfection less effective.

While disinfecting instruments and eliminating microorganisms are critical components of infection control, these processes are not the primary focus of cleaning itself. Disinfection involves using chemical agents to reduce or eliminate harmful microorganisms, while sterilization eliminates all forms of microbial life. However, these processes cannot succeed without adequate cleaning first, as the presence of soil can interfere with disinfecting agents' effectiveness. Therefore, emphasizing the removal of visible contaminants is what reinforces cleaning's role as the foundational practice in maintaining a safe and hygienic dental environment.
