Advantages of CT

Elimination of superimposition of

structures Improved contrast resolution

1% difference in physical density differences v

10% difference in conventional films

Multiplanar reformatted image This means that data can be viewed in either

coronal, axial, or sagital planes

Metal artifacts?

Worse low contrast detectability

Long scan times = motion artifacts Slightly Inferior quality to conventional CT

Periodontal ligament spaces easily recognizable in the

dental CT but not satisfactory in the CBCT
