Just like the panoramic, the patient stands or sits still while the sensor rotates around. It’s easiest to think of cone beam CT (computed tomography) as a 3-D version of a panoramic x-ray. For this reason, they are often used in diagnosing dental abscesses, which can be caused by infections or decay on the tooth root and are therefore not visible from the outside. Unlike bitewing x-rays, periapical x-rays look at the entire tooth, from crown to root. Periapical x-rays take a close look at just a few teeth at a time.

They are called bitewing because the patient bites down on a wing-shaped sensor or film while the x-ray machine takes the image. These are the type of x-rays patients are the most familiar with. In the last 122 years, dental x-rays have been continuously improved to be safer, gentler, & more accurate. The first dental x-ray was taken just 14 days after the discovery was announced. He called them x-rays because he didn’t know what they were, hence the “x”, and the name stuck. A German scientist named Wilhelm Conrad Roentgen discovered x-rays in 1895.
