Assessment of Periapical Radiographic Errors Frequency in Dental Radiology Department in Al-Maghrib Specialized Dental Health Center

This retrospective, cross-sectional study assesses the frequency and distribution of periapical radiographic errors in dental radiology, identifying common artifacts and their associations with dental regions. Conducted at the Radiology Unit of Al-Maghreb Specialized Dental Center, the study analyzed 312 periapical X-rays collected over six months (August 2023?January 2024). Error types, their frequency, and associated dental regions were recorded and statistically analyzed. The most frequent errors were "apex not shown in X-ray" (78%), followed by "cone cut" (10%). Errors were most common in posterior regions such as mandibular molars (28% on the right, 25% on the left) and maxillary premolars (27% on the right, 26% on the left). Chi-square analysis revealed significant associations between error type and region (p < 0.05). These findings highlight the need for improved radiographic protocols and operator training to minimize diagnostic inaccuracies in dental imaging.
