Dental x-rays

X-ray - teeth; Radiograph - dental; Bitewings; Periapical film; Panoramic film; Cephalometric x-ray; Digital image

Dental x-rays are a type of image of the teeth and mouth. X-rays are a form of high energy electromagnetic radiation. The x-rays penetrate the body to form an image on film or screen. X-rays can be either digital or developed on a film.

Structures that are dense (such as silver fillings or metal restoration) will block most of the light energy from the x-ray. This makes them appear white in the image. Structures that contain air will be black and teeth, tissue, and fluid will appear as shades of gray.
