Radiographic Spatial Frequencies Essential to the Diagnosis of Incipient Interproximal Lesions

The effects of selective obscuration of dental radiographs containing known incipient interproximal lesions suggest that the amount of resolution required for reliable diagnosis is anisotropic and can be related to the spatial frequency characteristics of the image. Frequencies less than the limiting resolution of existing screen-film techniques seem to be particularly important.
