| dc.description.abstract | 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<0.05 was considered statistically significant. Results In PWM setup, signal loss was higher in blue color at 1-,3-, and 5-minutes, but at 10-minutes, only the green light produced half-image. In LUX setup, signal loss was lower in green light. Contrast loss was lower in green light with LUX calibration. (p<0.05) Conclusion Among three colors compared, effect of exposure to green light prior to scanning of the irradiated PSP plates is found to be lower than the other colors | |
