Comparison of dental xeroradiography and conventional film techniques for the frequency and significance of image artifacts.
The frequency of occurrence and the classification of image artifacts were determined during a large-scale clinical dental radiographic study in which two conventional film techniques and xeroradiography were used. The resultant 1,220 radiographic images were evaluated for the presence of image artifacts. A list of commonly occurring artifacts was compiled, and frequency tables were constructed. Xeroradiography showed more image artifacts and also a higher retake rate due to artifacts (17.4% for individual images and 4.3% when images were evaluated as part of a complete-mouth survey). Many of the artifacts observed for xeroradiography were related to incomplete operator training and unfamiliarity with specialized imaging techniques.
