Panoramic radiography was studied with the aim to answer some questions about technical and diagnostic properties regarding dental diagnostics. A unit with an intraoral X-ray tube was studied regarding radiation beam area, absorbed doses, and image quality for various screen-film combinations. The beam area for lateral views was wider than optimal and the contact dose high. ⋯ Rotational and intraoral X-ray tube panoramic radiography perform equally well. Agreement between panoramic and intraoral radiography is not sufficient for panoramic radiography to be used alone to diagnose periapical lesions, marginal bone loss and caries. It is possible to perform a full-mouth survey with a combination of panoramic and intraoral radiography but when limited regions need to be examined intraoral radiography is the method of choice.
