“…To prevent this artifact, it is necessary to implement appropriate electromagnetic shielding, use the correct voltage source, ensure an uninterrupted power supply, and regularly maintain the scanner [10,13]. In a study conducted at two different institutes, Tashiro et al [8] determined a browser error rate of 52% in one institute. Additionally, C ¸alıs ¸kan & Sumer [10] stated that approximately 53% of PP artifacts were induced by the scanner.…”

Introduction. The advantages of phosphor plates (PPs), including their flexibility, thinness, and wireless connectivity, have contributed to their widespread use in dentistry alongside the advancement of digital radiography techniques. Continuous use of PPs and certain errors may lead to artifacts on the images. This retrospective study aimed to determine the frequency and types of intraoral PP artifacts. Methods. This study was conducted on 814 intraoral PP radiographs, including periapical and bitewing images. The errors and artifacts were classified into 4 main categories: technical errors, plate-related artifacts, scanner-induced artifacts, and ambient light artifacts. Results. A total of 656 periapical and 158 bitewing radiographs were examined. The most observed artifacts on the radiographs were plate-related artifacts, followed by technical errors (n=542, n=461, respectively). Within the category of plate-related artifacts, the most common artifacts were cracks or scratches (n=418, 77.1%), while within the category of technical errors, these were cone-cut errors (n=188, 40.7%). Parallel or zigzag radiopaque lines were the most common scanner-induced artifacts (n=313, 98.7%) and fading was the most common ambient light artefact (n=93, 49.2%). On more than half of the PPs, more than one artifact group was observed. Conclusions. Cone-cut, cracks/scratches, parallel zigzag radiopaque lines, and fading were common PP artifacts and errors in this study. The analysis revealed that over half of the PPs exhibited appearance of more than one artifact group. The high frequency of artifacts poses a risk of incorrect and incomplete diagnoses in radiographs, emphasizing the crucial importance of understanding the causes and developing effective prevention strategies for artifacts to enhance the reliability of diagnostic imaging and ensure the accuracy of patient assessments.

“…Additionally, depending on the ambient light and scanner, artifacts may occur on the plates, which may lead to loss of image analysis. Even with careful use, a loss in image quality has been reported when using PPs [6][7][8].…”

“…Still, electrons stored in the PSP plate are continually released over time. 16 In 2005, Akdeniz et al tested longevity of image quality in storage phosphor plates (SPPs) at various exposure settings, storage conditions, and delays in scanning. Fifteen PSP plates were exposed from 0.08 to 0.20 seconds and scanned immediately, 10, 30, and 60 minutes, and 24 hours after exposure.…”

Purpose This study aims to compare the effect of light exposure in red, green and blue (RGB) colors prior to scanning of the PSP plates. Materials & Methods An Arduino-based system is produced for standardized light exposure to the irradiated PSP plates. The system consisted of an Arduino Mega 2560 developer board, 2 RGB LED light sources, a TSL2591 digital light sensor and a DHT11 temperature and humidity sensor. A light-tight platform is produced with additive manufacturing and electronical units are integrated into this platform. A two-step alloy was used to create contrast. PSP system (VistaScan, Dürr Dental, Germany) is irradiated with fixed parameters of 70 kV, 8 mA and 0.5 seconds. Scanning of the PSPs were delayed for 1-,3-,5-, and 10-minutes, and half of the active surfaces are exposed to RGB lights independently in full brightness (PWM) and calibrated with lux while the rest is protected. MGVs are measured in 6 regions per image. The MGV differences in regions between conditions were examined by Kruskal-Wallis test. A p-value
