Dental X-Rays in Syracuse, NY

Dentists consider X-rays one of their best diagnostic tools in helping patients maintain good oral health. X-rays help dentists diagnose relatively common disorders such as cavities, periodontal disease and infections. Without this ability to see inside a tooth and beneath the gums, more disease would go unchecked, patients would experience more pain and discomfort and more teeth would be lost because proper treatment couldn’t be started in time.

At Smiles by Design we have “new” digital radiography. The digital x-rays replace the ordinary dental film with a flat electronic pad or sensor. The X-rays hit the pad the same way they hit the film. But instead of developing the film in a dark room, the image is electronically sent directly to a computer where the image appears on the screen. Digital radiography reduces radiation by as much as 80 percent. Digital X-rays are more detailed so that tiny changes that may not be noticeable with the naked eye or with the older style dental film can be caught earlier and more clearly with digital radiography. The image is then stored on the computer in your patient record.

The Major Dental Series of X-Rays

There are three major types of dental x-ray series: the initial full mouth series, the yearly bitewing series, and the Panoramic x-ray film.

Full mouth series

Bite Wings

The Full Mouth Series (FMS)

This is an example of full mouth series we take in our office. It consists of 4 bitewing films, which are taken at an angle specifically to look for decay, and 14 periapical films, which are taken from other angles to show the tips of the roots and the supporting bone. Not all full series look exactly like this one, but they all use some combination of bitewing and periapical X-rays to show a complete survey of the teeth and bones. We take a full mouth series on everyone over the age of 20 at the initial oral examination, and retake it again every 3 to 5 years.

The Bite Wings

A bitewing series consists of either 2 or 4 films taken of the back teeth with the patient biting down so the films contain images of both the top and bottom teeth. A bitewing series is the minimum set of x-rays that most offices take to document the internal structure of the teeth and gums. In our office, we take 2 on children under the age of 12, and 4 on everyone older, supplemented by the other periapical films associated with a full series of X- rays if the patient is over the age of 20.



The Panorex or Panoramic

As you can see from the image above, the Panoramic is a large, single x-ray film that shows the entire bony structure of the teeth and face. It takes a much wider area than any intra oral film showing structures outside of their range including the sinuses, and the Temperomandibular Joints. It shows many pathological structures such as bony tumors and cysts, as well as the position of the wisdom teeth. They are quick and easy to take, and cost about the same as full series of intraoral films. In addition to medical and dental uses, panoramic films are especially good for forensic (legal) purposes.

A Child’s Panoramic X-Ray

Above, you see a panoramic x-ray film of a child about 6 or 7 years old. You can see the adult teeth forming underneath the baby teeth. You see that the first molars (the 6-year molars) have erupted into place behind the last baby teeth in each arch, and so have the lower adult central incisors (you cannot see any lower baby centrals). But the upper adult central incisors have not yet erupted into position (you can see the upper baby centrals as little “stumps” sitting on top of the adult incisors). The adult second molars (the 12-year molars) are not expected to erupt until age 12. They are shown here only partly formed behind the fully erupted 6-year molars.
