What is Orthopantomography?

Background. An orthopantomogram (OPG) is a common radiograph used to identify the hard tissues of the oral cavity and surrounding skeletal structures. It is an extra-oral radiograph that approximates the focal trough of the mandible.

What is radiography technique?

Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography (“diagnostic” and “therapeutic”) and industrial radiography.

How is orthopantomogram done?

X-rays use radiation to take pictures of bones and other parts inside the body. An OPG is a panoramic X-ray of the upper and lower jaws, including the teeth. The OPG unit is specifically designed to rotate around the patient’s head during the scan. An OPG will take approximately 20 seconds.

What is dental Pantomograph?

A pantomogram is an X-ray of the entire oral cavity, which presents an image of the upper and lower jaw, temporomandibular joints, all teeth and sinuses.

What is IOPA xray?

Intra oral periapical radiography is a normally utilized intraoral imaging system in dental radiology and might be a segment of intraoral periapical radiologic examination. Periapical radiographs give vital data about the teeth and adjacent bone structure.

How many techniques are there in radiography?

In industrial radiography there are several imaging methods available, techniques to display the final image, i.e. Film Radiography, Real Time Radiography (RTR), Computed Tomography (CT), Digital Radiography (DR), and Computed Radiography (CR).

What is the purpose of radiography?

It is used to diagnose or treat patients by recording images of the internal structure of the body to assess the presence or absence of disease, foreign objects, and structural damage or anomaly. During a radiographic procedure, an x-ray beam is passed through the body.

Who invented OPG?

Horst Bergen is named as the inventor of the equipment. Fig 1-2 Panograph intraoral panoramic unit showing the slender x-ray tube.

What is ghost image in OPG?

A ghost image is a commonly observed artifact in an orthopantomogram whereby a dense, often metallic object is located between the source of x-ray and the focal center, resulting in a duplicate ‘ghost’ image at the contralateral aspect of the image.

What is a dental Pantomograph DPT?

(DPT) a special form of tomogram (see tomography) that provides a picture of all the teeth of both jaws on one film. Newer equipment can produce three-dimensional images of part of the jaw. From: dental pantomogram in Concise Medical Dictionary »
