My fellow hygiene coworkers and I are having a debate. Some of us feel that lead aprons are a thing of the past now that dental radiographs have gone digital. One hygienist, who recently graduated, said that lead aprons are required only for intraoral radiographs and not panoramic radiographs. I thought the thyroid guard was especially important. What is the correct answer? Are lead aprons required in dentistry with digital radiographs?
