Routine hand washing for dental healthcare personnel includes the use of?

  1. Water and antibacterial soap

  2. Hand sanitizer only

  3. Water and plain soap

  4. Sterile gloves without washing

The correct answer is: Water and plain soap

Routine hand washing for dental healthcare personnel should include the use of water and plain soap. Antibacterial soap is not recommended as it increases the risk of bacterial resistance and may not be any more effective than plain soap. Hand sanitizer should be used as a supplementary measure but should not replace hand washing with soap and water. Sterile gloves should not be used without proper hand washing first, as they can become contaminated during glove removal.
