What is one of the main safety measures for dental radiography?

Wearing a lead apron is one of the main safety measures for dental radiography because it serves as a protective barrier that absorbs scatter radiation and minimizes exposure to sensitive organs and tissues, particularly the reproductive organs and the thyroid gland. The lead material is effective in blocking harmful ionizing radiation, thus significantly reducing the patient's risk of radiation-related effects.

Choosing to not utilize appropriate protective equipment, like the lead apron, could increase the likelihood of radiation exposure, which can have adverse long-term health effects. Therefore, its use in the practice of dental radiography is paramount to ensure patient safety and compliance with radiation safety standards.
