Five hundred panoramic radiographs submitted to Delta Dental Plan of Michigan for preauthorization or claim processing were evaluated for frequency of occurrence of 15 categories of technical errors in patient positioning, film processing, and general film handling. Only one radiograph showed no errors. The average radiograph contained 2.2 positioning errors, 1.0 processing errors, and 1.5 miscellaneous errors, for a total of 4.7 errors. Of the 500 radiographs, 467 had positioning errors, 441 had processing errors, and 424 had miscellaneous errors. Diagnostic quality was judged to be adequate in 365 radiographs, inadequate in 91 radiographs and marginal in 44 radiographs. The severity of error was of more importance than the number of errors in the determination of diagnostic adequacy.
对提交给密歇根州三角洲牙科计划进行预先授权或理赔处理的500张全景X光片进行了评估，以确定患者体位、胶片冲洗和一般胶片处理中15类技术错误的出现频率。只有一张X光片没有错误。平均每张X光片有2.2个体位错误、1.0个冲洗错误和1.5个其他错误，总共4.7个错误。在这500张X光片中，467张有体位错误，441张有冲洗错误，424张有其他错误。365张X光片的诊断质量被判定为足够，91张不足，44张边缘。在确定诊断充分性时，错误的严重程度比错误数量更重要。
