• B. Use an alcohol-based hand rub only when hands are visibly soiled.
• C. Hand hygiene is optional.
• D. Wash with soap and water for at least 20 seconds or use an alcohol-based hand rub when hands are not visibly soiled.

Answer: (D)

Hand hygiene in a dental setting can be achieved by washing with soap and water for at least 20 seconds or by using an alcohol-based hand rub when hands are not visibly soiled. The best choice depends on cleanliness and context: if hands are visibly dirty or contaminated with bodily fluids, soap and water is preferred because it physically removes debris and microbes; when hands are clean, an alcohol-based hand rub quickly reduces microbial load. In dental practice, perform hand hygiene before patient contact and glove use, after removing gloves, and after contact with saliva, blood, or contaminated surfaces to prevent cross-contamination and protect both patients and staff.
