Additionally, the assessment included the examination of periapical lesions.Methods: A comprehensive analysis was conducted on 301 periapical digital radiographs to assess various factors including the type of post, type of coronal restoration, post length in relation to crown and root length, presence of any abnormalities in the post space, condition of the remaining gutta-percha (GP), gap between the end of the post and the GP, and the presence of apical lesions. Analysis was conducted to determine the frequency distribution and cross-tabulation of the variables.Results: Prefabricated metallic posts were most commonly used (62.1%), followed by metal posts which were found in 28.9% of the cases, and fiber posts which were used in 9.0% of the cases. The length of the posts in relation to the tooth were 2:1 in 32.6%, followed by 1:1 (27.9%) and 1:2 (23.6%). Parallel posts were used in 54.2% of cases, while the remaining 45.8% used tapered posts. Smooth posts were utilized in 77.1% of the cases, while serrated posts were utilized in 22.9%. Approximately 54.2% of the cases exhibited remaining GP of more than 5 mm, whereas 35.2% demonstrated adequate GP between 3– 5 mm and 8.0% with remaining GP less than 3 mm. According to the study’s findings, 65.1% of the samples under investigation had full coverage indirect restorations placed.Conclusion: It was found that the post and core procedures’ quality was comparable to earlier epidemiological studies. However, a significant proportion of posts were deemed to have poor technical quality, and apical periodontitis was seen in slightly more than one-third of the cases.Keywords: post and core system, apical status, technical quality, endodontically treated teeth, Saudi Arabia
