Can root fractures and cracks be diagnosed on tomography?

For a crack to be visible on tomography, its width must be more than twice the voxel resolution of the scan. For this reason, cracks are generally not visible, whereas obvious root fractures may be. Another limitation is artefacts caused by scattering. On CBCT, the radiopaque root filling and coronal restoration produce radiolucent lines around them. As a result, an appearance that is not a crack may mistakenly be diagnosed as one.
