Endodontically treated teeth have commonly lost most of their coronal structure. In order to restore them, an intrarradicular retainer is required to improve the restorations retention. Event though they have a proper clinical performance, their use has been related to failures such as root fractures. The aim of this systematic review was to analyze the outcome of clinical trials and cohort studies evaluating the post-retained restorations regarding the incidence rate of root fractures. The tested hypothesis was that the incidence rate related to the use of metal posts is higher than that of fiber posts. A search for clinical studies reporting the incidence of root fractures of restorations retained with fiber-reinforced composite posts or metal posts of endodontically treated teeth with more than 5-year of follow-up was conducted from inception to January 2014. Seven randomized clinical trials and 7 cohort studies were included. The overall incidence rate of root fractures was 5.13 (95% CI, 4.05-6.21) per 1000 posts-year. An almost 2-fold increase in the incidence rate of root fractures for prefabricated metal posts and carbon fiber posts compared with cast metal posts and glass fiber posts was observed, respectively. The pooled survival rate was 90% (95% CI, 85.5-93.3) for metal-based posts and 83.9% (95%, CI 67.6-92.8) for fiber-reinforced posts. The results of this study do not support the indication of fiber-reinforced posts based on a reduction of catastrophic failures. However, this review demonstrated the need for further well-designed clinical studies evaluating intra-radicular retainers.
