Which method is NOT suitable for disinfection of surfaces in a dental clinic?

Wiping with soap and water is generally not suitable for disinfection of surfaces in a dental clinic due to its limited ability to kill pathogens. While soap and water are effective for cleaning purposes, they do not possess the strong antimicrobial properties needed to eliminate potentially harmful microorganisms present in a dental environment. Disinfection requires agents that have been proven to effectively reduce or eliminate bacteria, viruses, and fungi, which soap and water alone cannot accomplish.

In contrast, the other methods listed—using EPA-registered disinfectants, alcohol-based cleaners, and fresh bleach solutions—are all accepted practices for disinfecting surfaces. These agents have specific formulations that establish their effectiveness against a wide range of pathogens, making them appropriate for use in a healthcare setting, particularly in areas where the risk of infection is high.
