When do thyroid collars need to be used for patients?

Thyroid collars are designed to protect the thyroid gland from unnecessary radiation exposure during radiographic procedures. The correct understanding of their use hinges on the context of the x-ray procedure being performed.

Using thyroid collars when the procedure allows it is essential because it ensures that the patient receives the maximum possible protection from scattered radiation, while simultaneously adhering to the specific requirements and protocols of each radiographic procedure. For instance, in certain imaging modalities, such as panoramic radiography, the design and positioning of the equipment may not accommodate the use of a thyroid collar.

Conversely, in scenarios where the collar can be effectively utilized without compromising the quality of the image or the procedure itself, utilizing it provides an additional layer of safety for the patient. This balanced approach respects both patient safety and the technical aspects of radiography.

The other options do not accurately represent the practice of using thyroid collars. Applying them universally to all x-ray procedures without consideration of the specifics may be impractical, and suggesting their use only for adults or during non-dental exams ignores the potential hazards for other patients, particularly children, who are more sensitive to radiation exposure.
