What is the appearance of the most common dental imaging technique errors?

One of the most common errors when exposing bitewing images is failing to prevent horizontal overlapping. Horizontal overlap is a result of the X-ray beam not passing through the open interproximal area at right angles to a properly positioned detector.

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.

What is a ghost image in dental?

Ghost images, or artifacts, are created by anatomical structures or objects that are located outside of the zone of focus or image layer but have a sufficient density to attenuate the X-ray beams, in turn producing distorted radiographic images.2 Although panoramic radiographs play a crucial role in diagnosis, these …

What does radiopaque mean in dentistry?

Radiopaque – Refers to structures that are dense and resist the passage of x-rays. Radiopaque structures appear light or white in a radiographic image.

What technique error would cause the image of the teeth on the radiograph to look too long?

Vertical alignment errors often occur with the bisecting angle technique and can result in elongation or foreshortening of the teeth.

Which is the most common error in intraoral radiography?

Incorrect exposure can be caused by many factors; the most common being improper exposure settings. Improper time selection is the most likely error because most intraoral x-ray units have fixed or unchangeable milliamperage (mA) and kilovoltage (kVp) settings.

What type of image would reveal recurrent decay?

Bitewing view Routine bitewing radiographs are commonly used to examine for interdental caries and recurrent caries under existing restorations.

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 ghosting in radiology?

Ghosting is a type of structured noise appearing as repeated versions of the main object (or parts thereof) in the image. They occur because of signal instability between pulse cycle repetitions. Ghosts are usually blurred, smeared, and shifted and are most commonly seen along the phase encode direction.

What appears radiopaque on a dental radiograph?

Radiopaque lesions of the jawbones are frequently encountered in dental radiographs. A variety of conditions such as chronic inflammation, soft tissue calcifications, fibrosseous lesions, odontogenic tumors, and bone neoplasms can manifest as radiopaque lesions on the jawbones.

What are the main issues that cause faulty radiologic images?

The most important causes include poor development, film fogging (including scattered radiation), and incorrect selection of exposure factors. This is the most common cause of poor contrast.
