Abstract
The purpose of this study was to evaluate the relationship of the quality of the postendodontic restoration and root canal obturation on the radiographic periapical status of endodontically treated teeth. Panoramic adiographs of randomly selected patients from the Department of Endodontics and Restorative Dentistry and the Department of Periodontology, School of Dental Medicine in Zagreb, were examined. Six hundred and ninety-six endodontically treated teeth from 265 panoramic radiographs were evaluated independently by two examiners. According to a predetermined radiographic set of criteria, the technical quality of the root filling of each tooth was scored as either good or poor, and the quality of the postendodontic restoration similarly good or poor. The apical one-third of the root and surrounding structures were then evaluated radiographically and the periapical status categorized as absence (API) or presence (PPI) of periradicular inflammation. The rate of API for all endodontically treated teeth was 45%. Good endodontic filling (GE) resulted in significantly more API cases than good postendodontic restoration (GR), 89% versus 68%. Poor endodontic filling (PE) resulted in slightly more PPI cases than poor postendodontically restoration (PR), 81% versus 79%. The combination of GE and GR had the highest API rate of 94%, significantly higher than PE and PR, with API rate of 14%. Differences among groups regarding the technical quality of the root filling, and the quality of the postendodontic restoration were statistically significant (p< 0.05).
