Aim  To investigate a number of clinical and treatment variables that might have influenced the prevalence of apical periodontitis in root‐filled teeth in a population of periodontally compromised patients. Methodology  This investigation was a retrospective cross‐sectional study on data collected from periodontal charts in addition to intra‐oral full‐mouth radiographs from patients attending the Department of Periodontology of the Dental School of the Ghent University Hospital. Periodontal parameters (clinical attachment loss and the lowest marginal bone level, the history of periodontal treatment), endodontic treatment (length, homogeneity and overall quality of the root filling) and the quality of coronal restorations were related to the prevalence of apical periodontitis. A total of 272 root‐filled teeth in 94 patients were evaluated. Results  The periapical condition was significantly influenced by the quality of the root filling and the coronal filling (P
