What can a panorex show?
A panorex X-ray is a two-dimensional X-ray used in the dental field. It displays both jaws, the upper and lower, as well as the teeth, on the same film at the same time.
What is an extraoral radiograph?
Abstract. Extraoral radiography means that both the image detector and the X-ray machine are placed outside the patient’s mouth. The X-ray source and the image detector have to be aligned in order to generate the desired image quality.
What is a periapical radiograph used for?
Periapical X-rays show the whole tooth — from the crown, to beyond the root where the tooth attaches into the jaw. Each periapical X-ray shows all teeth in one portion of either the upper or lower jaw. Periapical X-rays detect any unusual changes in the root and surrounding bone structures.
What are advantages of panoramic radiography?
Panoramic radiography has many advantages including short time for the procedure, greater patient acceptance and cooperation, overall coverage of the dental arches and associated structures (more anatomic structures can be viewed on a panoramic film than on a complete intraoral radiograph series), simplicity, low …
What is dental panorex?
Panoramic radiography, also called panoramic x-ray, is a two-dimensional (2-D) dental x-ray examination that captures the entire mouth in a single image, including the teeth, upper and lower jaws, surrounding structures and tissues. The jaw is a curved structure similar to that of a horseshoe.
What do occlusal radiographs show?
Occlusal X-rays show the roof or floor of the mouth and are used to find extra teeth, teeth that have not yet broken through the gums, jaw fractures, a cleft palate, cysts, abscesses or growths. Occlusal X-rays may also be used to find a foreign object.
What is the purpose of extraoral radiographs?
Extraoral radiographs provide images of larger areas such as the skull and jaws. In some instances an extraoral film may be necessary in a handicapped patient who cannot open his or her mouth for film placement or in a patient with swelling or severe pain who is unable to tolerate the placement of intraoral films.
What does extraoral mean?

Does a panorex show cavities?
Panoramic X-rays (also known as Panorex® or orthopantomograms) are wraparound photographs of the face and teeth. X-rays in general, expose hidden structures, such as wisdom teeth, reveal preliminary signs of cavities, and also show fractures and bone loss. Panoramic X-rays are extraoral and simple to perform.
What does a panoramic radiograph allow the dentist to see?
A panoramic x-ray allows us view your head, neck, and jaw, and how they work together as a whole, which means we can more easily identify cysts, tumors, growths, jaw abnormalities, and cancer.
How is panoramic radiography used in dental practice?
Panoramic radiography has become a commonly used imaging modality in dental practice and can be a valuable diagnostic tool in the dentist’s armamentarium. However, the panoramic image is a complex projection of the jaws with multiple superimpositions and distortions which may be exacerbated by technical errors in image acquisition.
How is radiography used in a Panorex procedure?
Panorex imaging uses the radiographic technique called tomography. During a panoramic procedure, the radiation source and image receptor rotate around the patient’s head in opposite directions while the patient remains stationary. This rotation produces a radiograph by imaging one area of the orofacial region while blurring other areas.
How long does a panoramic dental X-ray take?
Correct placement of the teeth and head is important for obtaining a clear image. You will be asked to remain very still while the rotating arm travels in a semicircle around the perimeter of your head and the images are being taken. This can typically last between 12 to 20 seconds.
Are there any side effects from a panoramic X-ray?
No radiation remains in a patient’s body after an x-ray examination. X-rays usually have no side effects in the typical diagnostic range for this exam. Panoramic x-rays can be used for very young children since the film does not have to be placed inside the mouth.
