In addition, the C-factor inside the root canal has been shown to be extremely high. Consequently, it can be concluded that bonding of posts to root canal dentin is still a challenge due to limited access, visibility, moisture control, reduced number of dentinal tubules in the apical third of the root, and deposition of cementum and secondary dentin. The most frequently occurring failure modes were post debonding and post fracture. However, a recently published observational clinical study demonstrated an annual failure rate of 4.6% after ten years. Prospective clinical investigations of endodontically treated teeth restored with adhesively-luted fiber reinforced composite posts (FRC posts) revealed survival rates of approximately 90% between 3 to 7 years вЂ“. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials, as detailed online in the guide for authors. There are no further patents, products in development or marketed products to declare. Finally, DMG, Hamburg, Germany provided 20 Fiber posts and the corresponding luting and adhesive system. Ivoclar Vivadent, Schaan, Liechtenstein gave 20 Fiber posts and the corresponding luting and adhesive system. Dentsply DeTrey, Konstanz, Germany supplied 20 Fiber posts and the corresponding luting and adhesive system. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.Д¬ompeting interests: For the present study the authors received the following donations: VOCO, Cuxhaven, Germany provided 20 Fiber posts and the corresponding luting and adhesive system.
