A comparative study of image quality and radiation exposure for dental radiographs produced using a charge-coupled device and a phosphor plate system

Aim To investigate the quality of periapical radiographic images produced by two digital dental radiography systems, a charge‐coupled device (CCD) and a photostimulable phosphor (PSP) image plate system, and to examine the overall radiation exposure when using these systems in a clinical setting. Methodology Patients were randomly allocated to both systems and the resultant radiographs rated for quality. The expected radiation exposure for an investigation was calculated. Results Overall, 98 images were acquired using the CCD system and 108 with the PSP system. The PSP system produced significantly higher quality (P
