What is the function of a thyroid collar during X-ray procedures?

• A. To protect the thyroid gland from radiation
• B. To stabilize the patient's jaw
• C. To enhance image quality
• D. To hold the film in place

Answer: (A)

The function of a thyroid collar during X-ray procedures is to protect the thyroid gland from radiation. The thyroid gland is particularly sensitive to ionizing radiation, which can increase the risk of thyroid cancer and other radiation-induced conditions. The thyroid collar serves as a protective barrier, ensuring that the sensitive area of the neck is shielded from unnecessary exposure during imaging procedures. While other options may relate to various aspects of dental X-ray procedures—such as stabilizing the jaw, enhancing image quality, or holding the film in place—they do not pertain specifically to the role of a thyroid collar. The primary and most critical function of the thyroid collar is the protection it provides against radiation, which is vital in maintaining patient safety during such diagnostic imaging.
