Which of the following is NOT a use of a dental mirror during examination?

• A. Taking x-rays
• B. Indirect vision
• C. Retraction
• D. Improved illumination

Answer: (A)

A dental mirror is used to help you see areas that aren’t directly visible, move tissues out of the way, and reflect light to improve visibility. Indirect vision lets you view the backside of teeth or tight spaces by looking in the mirror rather than straight in. Retraction uses the edge of the mirror or its handle to gently hold the cheek, lip, or tongue away from the working area, giving you more space to examine. Improved illumination comes from reflecting light onto surfaces that are shaded, making it easier to detect outlines and irregularities.

Taking x-rays, on the other hand, is done with radiographic equipment and a sensor or film, not the mirror. The mirror doesn’t contribute to image capture or exposure; it merely aids sight and access. So the option that is not a use of a dental mirror is taking x-rays.
