Assessment of apical periodontitis in relation to quality of root canal fillings and coronal restorations in a Turkish subpopulation: A retrospective cone-beam computed tomography study

Abstract

Introduction: This study aims to investigate the prevalence of apical periodontitis (AP) and relate the quality of root canal fillings (RCFs) and coronal restorations (CRs) with using cone-beam computed tomography (CBCT) in a Turkish subpopulation. Materials and Methods: A total of 824 CBCT scans were performed at the Dicle University Faculty of Dentistry between January 2015 and December 2017. The age, sex, root canal-Treated teeth of each patient, quality of RCF and CR, and CBCT periapical index (CBCTPAI) scores of teeth were calculated and recorded. Data were statistically analyzed. Results: Among 333 patients, 152 (45.6%) patients were male and 181 (54.3%) were female. The mean age was 30.1 ± 5.3 years. The total number of endodontically treated teeth was 550, and 76.2% had AP. In 238 (43.3%) teeth with inadequate RCF, AP rate was 89.4%. There was a significant correlation between the density of the RCF and AP (P < 0.00). Inadequate restorations accounted for 177 teeth (32.2%), of which 10.1% (18) of the teeth were CBCTPAI 1. Of the 41 teeth with missing CR, 39 (95.1%) teeth showed signs of AP. A significant difference was found between CR and AP (P = 0.00). Conclusions: The RCF quality, adequate CR, and the type of CR are related to AP. © 2020 Saudi Endodontic Journal | Published by Wolters Kluwer - Medknow.
