What is the primary function of a mouth mirror in dental practice?

1. To measure periodontal pockets

2. To reflect light into the oral cavity

3. To place medications in the oral cavity

4. To capture digital images of teeth

The correct answer is: To reflect light into the oral cavity

The primary function of a mouth mirror in dental practice is to reflect light into the oral cavity. This reflective quality allows dental professionals to visualize areas of the mouth that may be difficult to see directly, such as the back surfaces of teeth and other hidden structures. By illuminating the oral cavity, the mouth mirror enhances visibility, making it easier for dental practitioners to examine for any issues like cavities, gum disease, or other dental abnormalities. While measuring periodontal pockets, placing medications, and capturing digital images are important dental tasks, they are typically performed using other specific instruments designed for those functions. The mouth mirror serves as an essential tool in facilitating a thorough examination, ensuring that the dentist can provide the best care possible based on a complete assessment of the patient's oral health.
