A clinical comparison between xeroradiography and film radiography for the detection of recurrent caries.
Xeroradiographs and conventional film radiographs (D- and E-speed) were compared in a clinical study with the use of one-half complete-mouth radiographs for the detection of recurrent dental caries in 200 teeth. The results indicated that film was the most useful in identification of noncarious restored teeth (91% correct versus 79% correct for xeroradiography); however, xeroradiography was better than film for detection of recurrent caries (67% versus 53%). With ROC analysis, both film and xeroradiography were equally useful, having the same ROC value of 0.78. At rates of 67% and 53% for detection of the presence of recurrent caries, neither imaging system can overcome basic geometric limitations of superimposition of metallic restorations. Thus, there is the continued need for careful clinical assessesment of existing restorations for the presence of recurrent caries.
