What is the purpose of using a lead apron during dental radiography?

The primary purpose of using a lead apron during dental radiography is to protect the patient from radiation exposure. During radiographic procedures, ionizing radiation is used to create images of the teeth and surrounding structures. While the levels of radiation exposure from dental x-rays are generally low, it is essential to minimize any potential risks to patients, especially sensitive tissues such as those in the reproductive organs and the thyroid gland.

The lead apron acts as a barrier that absorbs and reduces the amount of scatter radiation that may reach the patient's body. By using this protective measure, dental professionals ensure that patients receive the benefits of diagnostic imaging while minimizing their exposure to unnecessary radiation, thereby adhering to the principle of "as low as reasonably achievable" (ALARA) in radiation safety protocols.
