Bitewing digital radiographs were taken and sharpening tool of digital software was applied on them. Then, a cavity was shaped on proximal surface of one randomly selected tooth from each block. At this stage, digital radiographs were again taken from blocks as mentioned above. 80 obtained images were printed 1:1 on film and were evaluated by an oral and maxillofacial radiologist. Data were analyzed by proportion test and kappa weighted test. </span></p> <p><font face="Times New Roman" size="3">&nbsp;</font></p> <p style="margin: 0cm 0cm 10pt text-align: justify -ms-text-justify: kashida text-kashida: 0%"><b><span new="" style="color: black line-height: 115% font-family:" times="">Results: </span></b><span new="" style="color: black line-height: 115% font-family:" times="">Positive predictive value and negative predictive value for direct digital radiography was 97% and 84.8% and after applying sharpening tool was 91.2% and 80.4%.
