The portion of a dental image that appears light or white is termed:

• radiolucent

• radiopaque

• dense

• high density

Which appears most radiolucent on a dental image?

• bone

• enamel

• dentin

• air space

Which appears most radiopaque on a dental image?

• bone

• enamel

• dentin

• air space

The overall blackness or darkness of an dental image is termed:

• density

• contrast

• subject thickness

• diagnostic quality

Increasing milliamperage (mA) will cause:

• increased density, darker image

• increased density, lighter image

• decreased density, darker image

• decreased density, lighter image

Increasing the operating kilovoltage (kV) will cause:

• increased density, darker image

• increased density, lighter image

• decreased density, darker image

• decreased density, lighter image

Increasing the exposure time will cause:

• increased density, darker image

• increased density, lighter image

• decreased density, darker image

• decreased density, lighter image

A dental patient has thick soft tissues and dense bones. To compensate for this increase in subject thickness and to provide an image of diagnostic density, the dental radiographer may:

• increase exposure time

• increase milliamperage

• increase kilovoltage

• any of the answers can be correct

The difference in the degrees of densities between adjacent areas on a dental image is termed:

• film contrast

• contrast

• subject thickness

• diagnostic quality
