Objective. The aim of this study was to compare the diagnostic accuracy of F-speed film and storage phosphor plate (SPP) exposed with different exposure times for the detection of artificial enamel subsurface demineralization. %26lt;br%26gt;Study Design. Standard enamel windows of extracted premolars were exposed to a demineralizing solution. All teeth were radiographed before and after acid application with F-speed films and SPPs. Films were exposed for 0.25 seconds and SPPs were exposed using 4 exposure times. Receiver operating characteristic analysis was used for diagnostic accuracy (A(z)). %26lt;br%26gt;Results. Significant differences were obtained among A(z)s of 0.08-versus 0.12-seconds and 0.10-versus 0.12-second exposed SPPs (P %26lt; .05). A(z)s of films were higher than the SPPs exposed with 0.08, 0.10, and 0.12 seconds (P %26lt; .05). No difference was found between the A(z)s of the 2 systems when SPPs were exposed for 0.16 seconds (P %26gt; .05). %26lt;br%26gt;Conclusions. Diagnostic accuracy of films and SPPs was not impaired when exposure time was 36% reduced for the latter; however, diagnosis was impaired when reduced 52%.
