Computerized tomosynthetic radiography in operative dentistry.

A study of 15 extracted teeth with carious lesions and artificially prepared defects adjacent to restorations compared the macroscopic morphology of the lesions and the extent of the defects with their appearance on conventional and computerized tomosynthetic radiography. Tuned Aperture Computerized Tomography offers advantages for the diagnosis of the extent of carious lesions and of defective restorations. The display of computer sections through teeth (slice images) allows a three-dimensional view to permit an assessment of the extent of carious lesions, restorations, and defects often masked in conventional radiography.
