Which of the following is a critical organ for dental radiography?

In dental radiography, the thyroid gland is recognized as a critical organ due to its sensitivity to ionizing radiation. The thyroid is particularly vulnerable because it can absorb and retain radioactive iodine, which can increase the risk of developing thyroid cancer following exposure to radiation.

While the eyes, hematopoietic tissue, and skin are also important and can be affected by radiation, they are not considered as critical in the context of dental procedures. The focus on the thyroid often leads to the implementation of protective measures, such as the use of lead aprons with thyroid collars, to minimize exposure during radiographic imaging. This understanding highlights the need for radiation safety in dental practices to protect vital organs, particularly those more sensitive to the effects of radiation.
