Identified errors and artifacts were classified according to their possible causes.

7 Additionally, especially for scanner artifacts, the user manuals of Digora PSP scanners (Kavo/Soredex, Helsinki, Finland) 8 and VistaScan Mini Easy PSP scanners (Dürr Dental, Bietigheim-Bissingen, Germany) 9 were consulted, and for software artifacts, the report of the American Association of Physicists in Medicine task group 10 and Seeram's study 11 were used. Image errors and artifacts were classified according to the classifications presented in the studies of Çalışkan and Sumer, 3 Chiu et al., 4 Shetty et al., 6 and Langland et al.
All the radiographs were evaluated by a single oral radiologist. The images were evaluated on an Eonis 22 monitor (MDRC-2222, Barco, Kortrijk, Belgium) under semi-dark lighting conditions. The first 250 images taken every month, between January 2017 and August 2018, for a total of 5000 periapical images, were examined. The digital imaging system in the hospital consists of 4 VistaScan Mini Easy PSP scanners (Dürr Dental, Bietigheim-Bissingen, Germany), 4 VistaScan Mini PSP scanners (Dürr Dental, Bietigheim-Bissingen, Germany), and 2-size and 0-size PSPs (Dürr Dental, Bietigheim-Bissingen, Germany, Apixia Phosphor Plates US).Īnonymized periapical radiographic images in the Digital Imaging and Communications in Medicine (DICOM) format were obtained from the Samsun Dental Hospital PACS system (Ak Dental Ltd., Samsun, Turkey) using the DICOM Query/Retrieve tool. The radiographic database of Samsun Dental Hospital was used for this study. In this study, the aim was to determine and classify dental PSP system artifacts in a comprehensive way according to the classifications proposed in previous studies.Įthical approval for this retrospective study protocol was obtained from the institutional review board (Ondokuz Mayıs University Ethics Committee of the Health Sciences). In previous studies, the effects of visible light on exposed PSPs and physical damage of the plates were emphasized comprehensively, but scanner and software errors were not mentioned in an all-inclusive manner. In Gulsahi and Secgin's study, 5 the effect of visible light on exposed PSPs was studied. 4 examined PSP artifacts under the headings of operator errors, scanning machine errors, and sensor defects. Çalışkan and Sumer 3 reported a comprehensive classification of intraoral PSP image errors and artifact types. Understanding this technology is very important for resolving image errors and obtaining successful radiographic imaging, as well as for developing innovations in the system. Furthermore, PSP has a lower spatial resolution and a higher image acquisition time additionally, more steps are needed to visualize the images compared to CCD and CMOS sensors. Despite these advantages, PSP is susceptible to bending and damage during handling, which causes permanent scratching on the receptor.
When compared to charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) direct digital sensors, PSP is thought to be more acceptable to patients because of its outstanding features such as wireless connectivity, flexibility, and thin design. In addition to these features, PSPs have a wide dynamic range that provides flexibility for correcting underexposed and overexposed images. PSP systems, which use digital radiology technology, are preferred over traditional radiology because of features such as lower radiation doses and higher acquisition speeds, and environmental advantages, since certain chemicals are not needed. 1 These systems include PSPs that are stimulated by light, a scanner that scans PSP data after exposure, a computer to record the data, and a software program for image processing. The first intraoral phosphor storage plate (PSP) (Digora, Orion Co./Soredex, Helsinki, Finland) system was introduced in 1994. In the practice of dental radiology, the use of digital intraoral imaging systems has become increasingly common from the 1980s to the present day, especially with recent developments in technology.
