Which instrument is included in a basic set-up?

• A. Mirror
• B. Handpiece
• C. X-ray Film
• D. Laser scaler

Answer: (A)

In a basic set-up, the items laid out are the instruments and materials you routinely need for a general exam and cleaning. The mirror is included because it serves several essential roles every day: it provides indirect vision, reflects light onto areas that are hard to see, and helps retract soft tissues like the lips and cheeks. These functions are needed in nearly every patient encounter, so the mirror is a standard, foundational instrument in the chairside setup. The other options are more specialized or consumable items that aren’t part of the everyday basic setup. A handpiece is a powered tool used for operative procedures, not something you typically lay out for a standard exam. X-ray film is a material used for radiographs rather than a handheld instrument, and a laser scaler is a specialized device used for periodontal therapy, not part of the routine chairside setup.
