According to a long-established protocol, biopsy specimens of bony lesions sent to the University of Washington Histopathology Service are accompanied by relevant radiographs. In this study, the authors evaluated the quality of 114 radiographs, both intraoral and panoramic, from 89 consecutive cases. The radiographs were judged on their clinical usefulness, rather than on criteria for technically ideal images, and on the severity, rather than the number, of errors. Only 33 percent of the panoramic radiographs were of acceptable quality, while the quality of the intraoral radiographs was markedly better. The most striking feature was the lack of three-dimensional radiographic coverage of the site of surgical exploration.
