BACKGROUND Digital radiography has recently been used in dentistry as a substitute for conventional film radiography *** imaging has many advantages and provides new possibilities for recording and interpreting radiographic *** system uses different types of digital *** To detect the frequency,type,and reasons behind the appearance of intraoral image artifacts acquired by photostimulable phosphor plates(PSP).METHODS This retrospective descriptive study was conducted in the oral and maxillofacial radiology unit of the dental clinics of the College of Dentistry,Princess Nourah University(PNU).All intraoral digital radiographs were acquired using(Gendex Expert DC.,United States)an intraoral X-ray machine with 7-mA,65-kVP using a PSP system(Soredex DIGORA Optime imaging plate)and laser scanners(Soredex DIGORA Optime),which can house all sizes of reusable intraoral PSP sensor plates with image acquisition software(MIPACS Dental Enterprise viewer 3.2.2).A total of 50000 intraoral radiographs were retrieved from the clinical database from April 2018 to April 2020 to evaluate the reason,type,and solutions to these image *** Overall,50000 intraoral digital radiographs were acquired in a two-year-period;that is,from April 2018 to April *** these,3550(7.1%)retakes were performed due to the presence of image *** radiographs were the most common image type of intraoral retakes(80.8%).Imaging artifacts were divided into three categories:operator,plate and scanning *** of 3550 retakes,5%,1.37%,and 0.73%were related to operator,plate,and scanning errors,*** cone cut was the most common operator error(988 images),Bite marks were the most common plate error(276 images),and delayed scanning artifacts were the most common scanning errors(145 images).The calculated kappa value for interobserver reliability was 0.99,indicating almost perfect interobserver *** Our study discussed intraora
