What is one purpose of thyroid collars during dental imaging?

Thyroid collars are specifically designed to minimize radiation exposure to the thyroid gland during dental imaging procedures. The thyroid is particularly sensitive to ionizing radiation, and even small doses can pose potential risks for conditions such as cancer. By using thyroid collars, a protective barrier is created around the neck area, effectively reducing the amount of scattered radiation that reaches the thyroid during X-ray procedures. This protective measure is in line with the principles of radiation safety, which prioritize limiting exposure to radiation wherever possible, particularly for vulnerable organs.

In this context, options related to enhancing imaging resolution or distributing radiation evenly do not align with the primary function of thyroid collars. Similarly, while stabilizing the patient's head may have its own importance during imaging, it is not the intended purpose of thyroid collars. The primary focus of these collars is centered around radiation protection.
