|Statement of the Problem: Different software capabilities have been used in digital systems to improve the diagnostic quality of radiographic images. |
Purpose: The present in vitro study aimed to determine the effect of the software capabilities on the diagnostic accuracy to determine the lengths of endodontic files in photostimulable phosphor (PSP) radiographs.
Materials and Method: In this in-vitro study, standard access cavities were prepared in 44 extracted human single-rooted permanent teeth. An endodontic file was placed in each root canal. PSP sensors were used for digital imaging using the parallel technique. All the images were displayed on a monitor; once normally with no software enhancement and once using software manipulations including pseudo-color, sharpness, emboss, and edge enhancement. The distance between the file tip and the rubber stop was measured on the images using an electronic ruler.
Results: All of the processing algorithms provided significantly shorter measurements than the true length. The results revealed the significant accuracy of the measured error in the pseudo-color enhancement technique compared to other techniques.
Conclusion: The results revealed significant differences between the initial measurements (the gold standard) and those made on the manipulated radiographs. In all cases, the measurements were significantly lower than the real values. Therefore, none of the image-processing algorithms significantly improved the measurement accuracy in this study However, manipulation with the pseudo-color option resulted in fewer errors compared to other options and the normal images. Pseudo-color algorithm may be recommended for accurate file length measurements when utilizing storage phosphor plates.
