Purpose: The aim of this study was to investigate the relationship between type of endodontic treatment and choice of definitive restoration and to show the prevalence of endodontic treatment options according to patient age and type of tooth. Materials and Methods: Data were collected from the archive system of the School of Dentistry, National and Kapodistrian University of Athens in Athens, Greece. The sample included endodontically treated teeth being restored definitively at the time of data collection. Results: Statistically significant difference was found regarding the type of restoration between initial endodontic treatments and retreatments (P .001). Conclusion: Endodontic retreatment seemed to have a significant effect on the choice of definitive restoration of the tooth.
