A panoramic dental x-ray, which surrounds the head, contains approximately twice as much radiation. Digital x-rays expose patients to 90 percent less radiation compared to conventional x-ray machines. Your new pediatric dentist will most likely need new x-rays using the older conventional X-ray method. A panoramic x-ray, also called a panoramic x-ray, is a two-dimensional (2D) dental x-ray that captures the entire mouth in a single image, including the teeth, upper and lower jaw, surrounding structures and tissues.
Rather than relying on a film placed inside the mouth, a panoramic x-ray machine projects a beam through the patient onto a film or detector that rotates in the opposite direction of the x-ray tube. Panoramic dental x-ray uses a very small dose of ionizing radiation to capture the entire mouth in one single dose image. While x-rays, or x-rays, contribute to a patient's overall exposure to radiation, it's well documented that the amount of radiation exposure on dental x-rays is very small compared to other x-rays.
