Digital Imaging in Dentistry chapter 8

In digital imaging, the term used to describe the picture that is produced is radiograph.

• True

• False

Digital imaging requires more x-radiation than conventional radiography.

• True

• False

The x-radiation source used in most digital imaging systems is a:

• conventional dental x-ray unit.

• charge-coupled device.

• storage phosphor plate.

• digital sensor.

Compared with film emulsion, the pixels used in digital imaging are structured in an orderly arrangement.

• True

• False

All intraoral exposure techniques for digital imaging are the same as those used for film-based imaging.

• True

• False

The manipulation of the original digital image is considered a legal issue.

• True

• False

Digital imaging was introduced to dentistry in:

• 1967

• 1977

• 1987

• 1997

Digital imaging can be used for:

• detecting conditions of teeth and surrounding structures.

• evaluating the growth and development of jaws.

• confirmation of suspected disease.

• all of the above.

Digital imaging requires less radiation than does conventional radiography because:

• the sensor is larger.

• the sensor is more sensitive to x-rays.

• the exposure time is increased.

• the pixels sense transmitted light quickly.

The image receptor found in the intraoral sensor is termed:

• CCD

• pixel

• cephalometric

• all of the above
