What is a periapical radiograph used for?
Similarly, it is asked, what is a periapical radiograph?
A periapical x-ray is one that captures the whole tooth. It shows everything from the crown (chewing surface) to the root (below the gum line). Each periapical x-ray shows a small section of your upper or lower teeth. These x-rays are often used to detect any unusual changes in the root and surrounding bone structures.
In respect to this, what are the three types of dental images?
There are three types of diagnostic radiographs taken in today's dental offices -- periapical (also known as intraoral or wall-mounted), panoramic, and cephalometric. Periapical radiographs are probably the most familiar, with images of a few teeth at a time captured on small film cards inserted in the mouth.
X-rays can also be used to detect dead nerves in teeth. Although x-rays cannot provide an image of soft tissue, once the dead nerve has caused damage to the bone surrounding the apex, or tip, of the root, it can be spotted on an x-ray film.
