There are two common categories of dental x-rays with a third category of dental x-rays becoming more popular.
During the most common category, Intraoral X-rays, a dental hygienist places the film for x-rays inside the mouth. The different types of Intraoral X-rays are:
- Bite-wing X-rays
- Periapical X-rays
- Occlusal X-rays
The second category, extraoral x-rays, require the dental hygienist or dentist Donald E. Larson to place the dental film for x-rays outside the mouth. Extraoral X-rays detect dental problems in the jaw and skull. The different types of Extraoral X-rays are:
- Panoramic X-rays
- Cephalometric X-rays
The latest technique for x-rays is Digital X-Rays. With Digital X-Rays, a flat electronic pad or sensor records the x-rays, and the captured image goes into a computer, where your dentist can view the x-rays on a digital screen, archive it or print it out.
