Operatory surfaces are noncritical and should be disinfected to reduce the microbial load to a safe level. Sterilization is reserved for instruments and not practical for broad environmental surfaces. High-level disinfection is more aggressive and is used for semi-critical items that contact mucous membranes; it’s not necessary for typical surfaces in a dental room. Low-level disinfection often isn’t enough to reliably inactivate many important pathogens. Intermediate-level disinfection provides broad coverage, inactivating a wide range of bacteria, many viruses, and mycobacteria, which is appropriate for cleaning operatory surfaces and reducing cross-contamination risk. Be sure to follow the product’s contact time for effective disinfection.
