Distribution and Radiographic Assessment of Post-retained Restorations: A Retrospective Study from Saudi Arabia

Introduction: Restoring endodontically treated teeth with significant coronal loss often requires intraradicular posts to provide retention for core build-up and definitive prostheses. The long-term success of these restorations depends on adherence to radiographic criteria such as optimal post-length, post-width, and adequate apical gutta-percha. Limited evidence exists regarding the prevalence and radiographic characteristics of post-retained restorations in the study population. Aim: To assess the distribution and radiographic quality of postretained restorations in a selected patient cohort. Materials and Methods: This retrospective study analysed patient records and radiographs obtained between April 2019 and October 2024 This retrospective study was conducted at the Department of Paediatric Dentistry and Orthodontics Sciences, College of Dentistry, King Khalid University, Abha, Saudi Arabia. The retrospective study analysed patient records and radiographs obtained between April 2019 and October 2024. A total of 625 radiographs were screened and 71 teeth with post-retained restorations from 61 adult patients, who met the inclusion criteria. Orthopantomogram (OPG), periapical, and bitewing radiographs were evaluated for tooth type, arch, posttype, post-length, post-width , and the remaining gutta-percha. Radiographic analysis was performed by a single examiner and descriptive statistics were calculated using Statistical Package for Social Sciences (SPSS) (p-value
