Which statement about creating a clean field is accurate?

• A. A clean field must be created using only paper towels
• B. A clean field can be created using paper towels or other approved barriers
• C. A clean field is optional during treatment
• D. A clean field must use a glass barrier

Answer: (B)

Establishing a clean field means set­ting up a defined, clean area on the treatment surface using barriers that prevent contaminants from reaching the site. Paper towels are an example of a clean barrier you can use, and many settings also allow other approved barriers, as long as they are clean and suitable for maintaining that field. The important point is that you are creating a clean working area with approved materials, not insisting on a single type of barrier. This helps prevent contamination during the procedure. A glass barrier isn’t a standard option, and treating the field as optional would undermine safety.
