The benefits of radiographic examination of symptomless edentulous patients are presented. Based on data from the literature, an estimate of the risk of fatal malignancy from such a procedure is provided. Because the benefits are considerable and the risks low, a recommendation for selective screening of edentulous patients is made.

The skills necessary to successfully perform radiological procedures in general dental practice are described and should be used as criteria when developing an effective undergraduate curriculum and as determinants of the contents of continuing education programmes. The present status of undergraduate curricula. continuing education, and postgraduate programmes as well as the recognition of the specialized nature of dento-maxillo-facial radiology, are discussed and recommendations for future developments are made.

A sample consisting of 1135 edentulous patients with clinically healthy denture bearing areas, was examined radiologically. It appears that the diagnostic yield is high whereas the expected radiation induced risk is low. Patients should therefore be examined radiologically prior to full denture construction.

A group of 1135 edentulous patients was investigated radiographically and clinically to determine the relation between elongated styloid processes and four symptoms frequently encountered in patients suffering from Eagle's syndrome. The radiologic finding of elongated styloid processes and/or ossification of the stylomandibular or stylohyoid ligaments occurred in about 30% of the patients. In female patients, facial pain and pain on turning the head appear to be related to the radiologic finding.
