What should be done with clinical contact surfaces that are not protected by barriers?

For clinical contact surfaces that are not protected by barriers, it is essential to disinfect them using a Cal/EPA registered germicide. This approach is necessary to prevent cross-contamination and enhance infection control in dental settings. Clinical contact surfaces, which can include areas like dental chairs, light handles, and countertops, can harbor pathogens that might pose a risk to patients and healthcare providers.

Using a registered germicide ensures that the disinfectant is effective against a wide range of microorganisms commonly found in a clinical environment. This process typically involves cleaning the surface to remove any debris or organic matter first, followed by the application of the disinfectant according to the manufacturer's instructions, ensuring proper contact time for effective disinfection.

The alternatives presented do not meet the standards necessary for effective infection control. Not treating the surfaces, just cleaning with water, or covering them with plastic wrap alone do not provide sufficient protection against the potential spread of infectious agents. Therefore, employing a registered germicide is the correct and recommended practice for ensuring a safe clinical environment.
