Objectives
Endodontically treated teeth (ETT) often have significant structural damage and require multiple reinforcing methods during the reconstruction process. The aim of this study was to evaluate the complication rates of ETT with and without a post.
Materials and Methods
The study investigated various clinical factors, including technical complications as well as biological complications. All patients who had previously received cemented fixed dental prostheses (FDPs) were subjected to clinical and radiographical examinations during their follow-up visits. Clinical and radiographic assessments were performed to determine the cumulative survival rate, and life table survival analyses of FDPs in the presence of complications were performed.
Results
The study included 287 ETT evaluated in this study, in which 219 were placed in females and 68 in males, with an average follow-up time of 82.4 months. There were no significant differences between ETT with a post and ETT without a post with regard to the complication rates. Furthermore, no significant differences were found (p-value = 0.102) in the complication rates between types of final restoration. The complication rates of the FDPs wthout a post revealed a survival rate of 58% after 5 years, 44% after 10 years, and 29% after 15 years. However, these differences were not significant (p-value = 0.830). On the other hand, the cumulative survival rate of the FDPs with a post was 50% after 5 years, 30% after 10 years, and 21% after 15 years.
Conclusions
ETT restored with FDPs with or without a post can show similar complication rates in a long-term evaluation. Furthermore, the types of final restoration may not have an effect on the complication rate.
