The X ray is a tool of inestimable value in establishing a diagnosis and in follow-up studies. However, the radiographic findings do not always accurately reflect the existence of normal or pathogenic conditions at the apexes of teeth, or in the mandible and maxilla, represented by metastatic or certain systemic lesions. A considerable body of confirming literature has accumulated since we first showed that experimental bone lesions, created within the cancellous structure and not encroaching on the junction region between cancellous and inner surface of cortical bone, cannot be visualized on radiographs. 1-6 The aforementioned studies emphasize that routine clinical radiographs may not detect the presence of inflammatory lesions or neoplasms causing bone destruction. Whereas minute or small lesions 7 have been acknowledged. to go undetected, it has not been recdgnized that large lesions may also go undetected (Fig 1).Besides the experimental evidence, there is also histologic and clinical evidence of apical and periodontal disease without correlative radiographic manifestations? Human necropsy material has shown that, in many instances, radiographic examinations had negative results when cancellous bone was diseased and sometimes when cortex was involved. Furthermore, necrotic pulps invariably cause
