Types of  Digital Dental X-rays

Digital x-rays use a sensor instead of film to capture an image. The

Information gathered is the same as any other x-ray, but the amount

of radiation is considerably less and because it is digitally acquired, it

can be manipulated in size allowing magnification for closer viewing.

Bite-wing x-rays (cavity detecting x-rays) can detect decay in

between the teeth and changes in the bone that supports

the teeth.

A periapical x-ray shows several teeth including the crown of the

tooth and all of the roots and bones of the teeth.  This x-ray shows

Abscesses, periodontal conditions, tumors, and even bone patterns

of some systemic diseases (diseases of the entire body).


A complete mouth series is a combination of the bite-wing x-rays

and the periapical films and consists of 18 to 21 images.   

A panoramic x-ray shows all the upper and lower teeth,  

large portion of the jaws, and other structures on one large image.

This film can detect cysts, impacted teeth, retained root

fragments, fracture and other conditions of the jaw.  This x-ray is

not as good as the bite wing or periapical x-rays at detecting

decay or periodontal conditions.

At any one time, either or all of these tools may be required for

diagnostic reasons as each of them serve a different purpose.
