Background and Objectives: Early detection of secondary proximal caries is critical for preservation of tooth vitality. This study sought to assess and compare the diagnostic accuracy of DIAGNOdent and digital radiography for detection of secondary proximal caries adjacent to composite restorations.
Materials and Methods: Sixty extracted molars including 30 teeth with carious lesions and 30 sound teeth were randomly selected. Class II cavities were prepared in all teeth and carious dentin was intentionally left in the gingival floor of cavities in 30 carious teeth. All cavities were restored with composite resin. The teeth were mounted in wax blocks (three teeth per block) and examined for caries using DIAGNOdent) kaVo Dental,Biberach,Germany). Digital radiographs using DIGORA Photostimulable Phosphor plates (PSP) (Soredex Corporation, Helsinki, Finland ) were obtained from all teeth using the parallel technique and were evaluated by four observers. Repeated measure ANOVA was applied to calculate sensitivity and specificity values of the two diagnostic techniques. Receiver operating characteristic (ROC) curve was plotted for DIAGNOdent results and based on that, the cutoff points were determined. 
Results: The sensitivity and specificity values at the cut-off point of 10.5 were 0.622±0.038 and 0.822±0.077 for DIAGNOdent and 0.591±0.093 and 0.891±0.083 for digital radiography, respectively. The area under the ROC curve was 0.7 for DIAGNOdent. Weighted kappa revealed moderate to almost perfect intra-observer agreement (0.46-0.99). Intraclass correlation coefficient (ICC) for DIAGNOdent was calculated to be 0.88.
Conclusion: No statistically significant difference was noted in diagnostic accuracy of DIAGNOdent and digital radiography for detection of secondary proximal caries adjacent to composite restorations. Thus, DIAGNOdent may be used as an adjunct diagnostic tool for detection of secondary proximal caries beneath composite restorations.

Delegates from which countries presented in the congress? : USA, India, Thailand, UK, Japan, turkey, Belgium
Were the delegates of any other organizations present in the congress? : Yes
If yes, please write the names of the organizations in the box : International association of oral and maxillofacial radiology, Asian association of oral and maxillofacial radiology
What were the responses to your talking points? Were specific questions or concerns raised? : There were not any responses
If you met staff members, please list their full names & positions. : Dr. Kaan Orhan, Dr. Mustafa Alkhader
Please inform us if there are any follow up actions we need to talk with the members of the congress : There are not any follow up
Your experiences about the travel processes(Providing ticket, accommodation,...) : The procedure for getting VISA was very complicated and time consuming. Because there isn’t embassy of Taiwan in Iran and I sent my documents to UAE for getting ViSA. I got my VISA in the last minutes.So unfortunately There wasn’t any Iranian participants except me.
Please give a briefing of your own observations and outcomes of the congress: : This congress was one of the greatest gathering of oral and maxillofacial radiologist from all over the world. I also saw many scientists of oral radiology, from United States, to European countries and Asian ones, who are very famous with many publications. lectures were so interesting and I found good opportunities to discuss and cooperation with professors and researchers.
