Why it matters for dental
Dental clinicians handling saliva may encounter non-enveloped viruses that resist alcohol-based hand rubs, so knowing when to wash with soap and water reduces the chance of cross-contamination between patients and staff.
Key points
- 01
CDC guidance states alcohol-based hand rubs are allowed for routine dental exams and nonsurgical procedures, but soap and water must be used when hands are visibly soiled.
- 02
HPV and enteric viruses such as norovirus and rotavirus have a non-enveloped capsid that alcohol cannot penetrate, leaving these pathogens on hands after sanitizer use.
- 03
Soap micelles formed during handwashing physically remove non-enveloped viruses from skin without needing to inactivate them.
- 04
CDC instructs health-care workers to rub hands vigorously with soap and water for at least 15 seconds to achieve adequate removal of resistant viruses.
