Abstract

Purpose: This double-blind randomized clinical trial (RCT) aimed to evaluate the 2-year survival rates of endocrowns and partial coverage ceramic restorations (PCCR) with fiber posts. Material and Methods: Forty (40) participants fulfilled the elegibility criteria, and they were randomly allocated in 2 groups: Endocrown or PCCR+post. The survival rates were assessed based on USPHS modified and radiographic examinations. A Chi-square test was used to assess the distribution of characteristics between groups. Kaplan-Mei-er and Log-rank tests were used to estimate the survival rate. To evaluate the association between survival of the restorations and the explanatory variables, the Multivariate Cox regression model was used. Only variables presenting p<0.20 were maintained in final model (alpha= 0.05). Results: The highest 2-year survival rates were recorded for the Endo-crown group (100%), whereas the PCCR+post group exhibited the lowest performance (66.7%). Most of the restoration failures was due to lack of marginal adaption, fracture, and recurrent caries. Cox Regression unadjusted analysis showed that only type of restoration presented a significant effect (p<0.20). Thus, adjusted analysis was not per-formed. Conclusions: Endocrowns appear to be a promising conservative restorative op-tion and to be feasible and reliable approach restoring endodontically treated posterior teeth, showing higher 2-year overall survival rates than the PCCR+post.
