Objectives
The aim of this retrospective cohort study was to determine the prevalence and correlations between root canal treatment, periapical status, and coronal restoration detected using cone beam computed tomography (CBCT) in elderly Polish population (60-79 years).
Materials and Methods
A total of 480 CBCT images were assessed. Collected data included: age, gender, the tooth location, the type and quality of the prosthetic restoration, and apical periodontitis (AP).
Results
There was a statistically significant correlation between the age of the patients and the number of preserved teeth; with age, the number of teeth in patients decreased. A crown with overhangs, open margins or caries adjacent to restoration (inadequate prosthetic restoration) was associated with an increased prevalence of AP (p <0.05). The type of prosthetic restoration (single crown vs. bridge abutment) was associated with the apical periodontitis, lesions were found significantly more frequently in the bridge abutment teeth than in single crown abutments (p <0.05). Moreover, the presence of a post metal/non-metal was significantly associated with the AP.
Conclusions
Inadequate prosthetic restoration and the presence of posts were associated with increased prevalence of AP.
