Standard enamel windows of extracted premolaiographed before and after acid application with F-speed filre exposed using 4 exposure times. The aim of this study was to compare the diagnostiposed with different exposure times for the detection of artifidy Design.

The evaluation of exposure time for blue Digora Optimeplates for proximal caries diagnosis used 10%-25% ofthe exposure time needed for that of Ekta-Plus film.3However, we could find no study testing various levelsof exposure time reductions with the use of blue DigoraOptime plates and F-speed film for detection of inter-proximal subsurface demineralization. The only study includingĮ7t again, the effect of different exposure times was notted.The greatest difficulty in caries detection involvesrly demineralization, which is confined only to theamel.8,9 The capacity of several radiographic meth-s for detection of different degrees of enamel demin-lization was investigated in many studies.8,10-12 In So far, the effect of exposure time oncaries diagnosis with the use of blue Digora SPPs hasnot been studied adequately. In anotherstudy, Pontual et al.7 compared F-speed (Insight) filmwith the blue SPPs of the new version of the Digorasystem (Optime) regarding proximal caries detection butesĬlinical tasks.
